1、創建文件夾

//using
System.IO;
Directory.CreateDirectory(%%1);

2、創建文件

//using
System.IO;
File.Create(%%1);

3、刪除文件夾
//using
System.IO;
Directory.Delete(%%1);

4.刪除文件
//using
System.IO;
File.Delete(%%1);

5.刪除一個目錄下所有的文件夾

 1 //using 
 2 System.IO;
 3 foreach (string dirStr in Directory.GetDirectories(%%1))
 4 {
 5       DirectoryInfo dir = new DirectoryInfo(dirStr);
 6       ArrayList folders=new ArrayList();
 7       FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
 8      for (int i = 0; i < folders.Count; i++)
 9     {
10          FileInfo f = folders[i] as FileInfo;
11          if (f == null)
12         {
13              DirectoryInfo d = folders[i] as DirectoryInfo;
14              d.Delete();
15           }
16      }
17 }

6、清空文件夾
//using
System.IO;
Directory.Delete(%%1,true);
Directory.CreateDirectory(%%1);

7、讀取文件
7.1.操作系統默認編碼

//using 
System.IO;
StreamReader s = File.OpenText(%%1);
string %%2 = null;
while ((%%2 = s.ReadLine()) != null){
         %%3
}
s.Close();

7.2.UTF-8編碼
/*
using
System.IO;
using System.Text;
*/
StreamReader srfile = new
StreamReader(%%1,Encoding.UTF8);
while ((String %%2 = srfile.ReadLine()) !=
null)
{
%%3
}
srfile.Close();

7.3.分塊讀取
/*
using
System.IO;
using System.Text;
*/
try
{
FileStream fs=new
FileStream(%%1,FileMode.Open,FileAccess.Read);
BinaryReader br=new
BinaryReader(fs,new ASCIIEncoding());
byte[]
chunk;
do
{
chunk=br.ReadBytes(10240);
if(chunk.Length>0)
{
%%2
//chunk,chunk.Length
}
}
while(chunk.Length>0);
fs.Close();
}
catch
{
//return
-1;
}

8.寫入文件
//using System.IO;
FileInfo f = new
FileInfo(%%1);
StreamWriter w =
f.CreateText();
w.WriteLine(%%2);
w.Flush();
w.Close();

9.寫入隨機文件
//using
System.IO;
byte[] dataArray = new byte[100000];//new
Random().NextBytes(dataArray);
using(FileStream FileStream = new
FileStream(%%1, FileMode.Create)){
// Write the data to the file, byte by
byte.
for(int i = 0; i < dataArray.Length;
i++){
FileStream.WriteByte(dataArray[i]);
}
// Set the stream position
to the beginning of the file.
FileStream.Seek(0, SeekOrigin.Begin);
//
Read and verify the data.
for(int i = 0; i < FileStream.Length;
i++){
if(dataArray[i] !=
FileStream.ReadByte()){
//寫入數據錯誤
return;
}
}
//"數據流"+FileStream.Name+"已驗證"
}

10.讀取文件屬性
//using
System.IO;
FileInfo f = new
FileInfo(%%1);//f.CreationTime,f.FullName
if((f.Attributes &
FileAttributes.ReadOnly) !=
0){
%%2
}
else{
%%3
}

11.寫入屬性
//using
System.IO;
FileInfo f = new FileInfo(%%1);
//設置只讀
f.Attributes =
myFile.Attributes | FileAttributes.ReadOnly;
//設置可寫
f.Attributes =
myFile.Attributes &
~FileAttributes.ReadOnly;

12.枚舉一個文件夾中的所有文件夾
//using
System.IO;
foreach (string %%2 in
Directory.GetDirectories(%%1)){
%%3
}
/*
DirectoryInfo dir = new
DirectoryInfo(%%1);
FileInfo[] files =
dir.GetFiles("*.*");
foreach(FileInfo %%2 in
files){
%%3
}
*/

13.復制文件夾
/*
using System.IO;
using
System.Collections;
*/
string path =
(%%2.LastIndexOf(Path.DirectorySeparatorChar) == %%2.Length - 1) ? %%2 :
%%2+Path.DirectorySeparatorChar;
string parent =
Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path +
Path.GetFileName(%%1));
DirectoryInfo dir = new
DirectoryInfo((%%1.LastIndexOf(Path.DirectorySeparatorChar) == %%1.Length - 1) ?
%%1 : %%1 + Path.DirectorySeparatorChar);
FileSystemInfo[] fileArr =
dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new
Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while
(Folders.Count>0)
{
FileSystemInfo tmp = Folders.Dequeue();
FileInfo
f = tmp as FileInfo;
if (f == null)
{
DirectoryInfo d = tmp as
DirectoryInfo;
Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf(Path.DirectorySeparatorChar)
== parent.Length - 1) ? parent : parent + Path.DirectorySeparatorChar,
path));
foreach (FileSystemInfo fi in
d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.CopyTo(f.FullName.Replace(parent,
path));
}
}

14.復制目錄下所有的文件夾到另一個文件夾下
/*
using
System.IO;
using System.Collections;
*/
DirectoryInfo d = new
DirectoryInfo(%%1);
foreach (DirectoryInfo dirs in
d.GetDirectories())
{
Queue<FileSystemInfo> al = new
Queue<FileSystemInfo>(dirs.GetFileSystemInfos());
while (al.Count >
0)
{
FileSystemInfo temp = al.Dequeue();
FileInfo file = temp as
FileInfo;
if (file == null)
{
DirectoryInfo directory = temp as
DirectoryInfo;
Directory.CreateDirectory(path + directory.Name);
foreach
(FileSystemInfo fsi in
directory.GetFileSystemInfos())
al.Enqueue(fsi);
}
else
File.Copy(file.FullName,
path + file.Name);
}
}

15.移動文件夾
/*
using System.IO;
using
System.Collections;
*/
string filename = Path.GetFileName(%%1);
string
path=(%%2.LastIndexOf(Path.DirectorySeparatorChar) == %%2.Length - 1) ? %%2 :
%%2 + Path.DirectorySeparatorChar;
if (Path.GetPathRoot(%%1) ==
Path.GetPathRoot(%%2))
Directory.Move(%%1, path +
filename);
else
{
string parent =
Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path +
Path.GetFileName(%%1));
DirectoryInfo dir = new
DirectoryInfo((%%1.LastIndexOf(Path.DirectorySeparatorChar) == %%1.Length - 1) ?
%%1 : %%1 + Path.DirectorySeparatorChar);
FileSystemInfo[] fileArr =
dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new
Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count
> 0)
{
FileSystemInfo tmp = Folders.Dequeue();
FileInfo f = tmp as
FileInfo;
if (f == null)
{
DirectoryInfo d = tmp as
DirectoryInfo;
DirectoryInfo dpath = new
DirectoryInfo(d.FullName.Replace((parent.LastIndexOf(Path.DirectorySeparatorChar)
== parent.Length - 1) ? parent : parent + Path.DirectorySeparatorChar,
path));
dpath.Create();
foreach (FileSystemInfo fi in
d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.MoveTo(f.FullName.Replace(parent,
path));
}
}
Directory.Delete(%%1,
true);
}

16.移動目錄下所有的文件夾到另一個目錄下
/*
using System.IO;
using
System.Collections;
*/
string filename = Path.GetFileName(%%1);
if
(Path.GetPathRoot(%%1) == Path.GetPathRoot(%%2))
foreach (string dir in
Directory.GetDirectories(%%1))
Directory.Move(dir,
Path.Combine(%%2,filename));
else
{
foreach (string dir2 in
Directory.GetDirectories(%%1))
{
string parent =
Path.GetDirectoryName(dir2);
Directory.CreateDirectory(Path.Combine(%%2,
Path.GetFileName(dir2)));
string dir =
(dir2.LastIndexOf(Path.DirectorySeparatorChar) == dir2.Length - 1) ? dir2 : dir2
+ Path.DirectorySeparatorChar;
DirectoryInfo dirdir = new
DirectoryInfo(dir);
FileSystemInfo[] fileArr =
dirdir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new
Queue<FileSystemInfo>(dirdir.GetFileSystemInfos());
while
(Folders.Count > 0)
{
FileSystemInfo tmp =
Folders.Dequeue();
FileInfo f = tmp as FileInfo;
if (f ==
null)
{
DirectoryInfo d = tmp as DirectoryInfo;
DirectoryInfo dpath =
new
DirectoryInfo(d.FullName.Replace((parent.LastIndexOf(Path.DirectorySeparatorChar)
== parent.Length - 1) ? parent : parent + Path.DirectorySeparatorChar,
%%2));
dpath.Create();
foreach (FileSystemInfo fi in
d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.MoveTo(f.FullName.Replace(parent,
%%2));
}
}
dirdir.Delete(true);
}
}

17.以一個文件夾的框架在另一個目錄創建文件夾和空文件
/*
using
System.IO;
using System.Collections;
*/
bool b=false;
string path =
(%%2.LastIndexOf(Path.DirectorySeparatorChar) == %%2.Length - 1) ? %%2 : %%2 +
Path.DirectorySeparatorChar;
string parent =
Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path +
Path.GetFileName(%%1));
DirectoryInfo dir = new
DirectoryInfo((%%1.LastIndexOf(Path.DirectorySeparatorChar) == %%1.Length - 1) ?
%%1 : %%1 + Path.DirectorySeparatorChar);
FileSystemInfo[] fileArr =
dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new
Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count
> 0)
{
FileSystemInfo tmp = Folders.Dequeue();
FileInfo f = tmp as
FileInfo;
if (f == null)
{
DirectoryInfo d = tmp as
DirectoryInfo;
Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf(Path.DirectorySeparatorChar)
== parent.Length - 1) ? parent : parent + Path.DirectorySeparatorChar,
path));
foreach (FileSystemInfo fi in
d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
if(b)
File.Create(f.FullName.Replace(parent,
path));
}
}

18.復制文件
//using
System.IO;
File.Copy(%%1,%%2);

19.復制一個文件夾下所有的文件到另一個目錄
//using
System.IO;
foreach (string fileStr in
Directory.GetFiles(%%1))
File.Copy((%%1.LastIndexOf(Path.DirectorySeparatorChar)
== %%1.Length - 1) ? %%1 +Path.GetFileName(fileStr): %%1 +
Path.DirectorySeparatorChar+Path.GetFileName(fileStr),(%%2.LastIndexOf(Path.DirectorySeparatorChar)
== %%2.Length - 1) ? %%2 +Path.GetFileName(fileStr): %%2 +
Path.DirectorySeparatorChar+Path.GetFileName(fileStr));

20.提取擴展名
//using
System.IO;
string %%2=Path.GetExtension(%%1);

21.提取文件名
//using
System.IO;
string %%2=Path.GetFileName(%%1);

22.提取文件路徑

//Traditionally grep
stands for "Global Regular Expression Print".
//Global means that an entire
file is searched.
//Regular Expression means that a regular expression string
is used to establish a search pattern.
//Print means that the command will
display its findings.
//Simply put, grep searches an entire file for the
pattern you want and displays its findings.
//
//The use syntax is
different from the traditional Unix syntax, I prefer a syntax similar
to
//csc, the C# compiler.
//
// grep [/h|/H] - Usage Help
//
//
grep [/c] [/i] [/l] [/n] [/r] /E:reg_exp /F:files
//
// /c - print a count
of matching lines for each input file;
// /i - ignore case in pattern;
//
/l - print just files (scanning will stop on first match);
// /n - prefix
each line of output with line number;
// /r - recursive search in
subdirectories;
//
// /E:reg_exp - the Regular Expression used as search
pattern. The Regular Expression can be delimited by
// quotes like "..." and
'...' if you want to include in it leading or trailing blanks;
//
//
/F:files - the list of input files. The files can be separated by commas as in
/F:file1,file2,file3
//and wildcards can be used for their specification as
in /F:*file?.txt;
//
//Example:
//
// grep /c /n /r /E:" C Sharp "
/F:*.cs

public
OpenFileDialog ofdlg = new OpenFileDialog();//打開文件對話框
public string
filename;

public
Form1()
{
InitializeComponent();
}

private void
button1_Click(object sender, EventArgs e)
{
ofdlg.Filter =
"pdf文件(*.pdf)|*.pdf";//選擇pdf文件
if (ofdlg.ShowDialog() ==
DialogResult.OK)
{
filename = string.Format("{0}",
ofdlg.FileName);
}
}
//傳送打開文件對話框中得到的filename來做為外部程序的參數來做轉化
private
void button2_Click(object sender, EventArgs e)
{
Process p = new
Process();
string path = "pdftotext.exe";
//進程啟用外部程序
//這個exe我放在debug文件夾下面
p.StartInfo.FileName =
path;
p.StartInfo.Arguments = string.Format( filename + "
-");//很怪異的一行
//參數“－”表示可以得到輸出流
p.StartInfo.UseShellExecute =
false;
p.StartInfo.RedirectStandardInput =
true;
p.StartInfo.RedirectStandardOutput =
true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow
= true;

p.Start();
string s =
p.StandardOutput.ReadToEnd();//得到pdf文檔中的文本內容
textBox1.Text =
s;
p.Close();
}
}

上面的程序運行后，如果是在Debug文件夾下的pdf文件就可以得到輸出，可是如果在打開文件對話框中打開我桌面上的一個pdf如：@"d:\我的文檔\test.pdf"，輸出就會是空，但是如果把上面那怪異的一行改為：
C#
code
p.StartInfo.Arguments = string.Format( @"d:\我的文檔\test.pdf" + "
-");

程序就又會得到輸出。
呵呵，謝謝樓上的兄台，下載的xpdf中xpdftotext.exe用到的配置文件xpdfrc需要手動配置，我如果把那些字體啊，什么的映射成絕對路徑下的文件，就不會出現上面的問題，但是我把配置文件中的路徑改成了相對路徑，於是就出現了上面的問題了，看兄台能夠很輕易的就運行成功，一定是做過很多代碼的，這里還得勞煩兄台再給看一下，幫下忙，能遇到一個大神不容易，大神可不能吝嗇啊，先謝過了哈

95.報表相關
/*
using
CrystalDecisions.CrystalReports.Engine;
using
CrystalDecisions.Shared;
*/
2、水晶報表的兩種格式
1）pull模式,不利用DataSet,直接從數據庫中取出數據
2)
push模式,使用DataSet,利用它進行數據的加載和處理等
3.
水晶報表使用的庫
1)水晶報表的引擎(CREnging.dll),作用:合並數據,裝換格式
2)水晶報表設計器(CRDesigner.dll),作用：設計標題，插入數據等
3）水晶報表查看控件（CRWebFormViewer.DLL）
4)需要引入的命名空間
using
CrystalDecisions.CrystalReports.Engine;
using
CrystalDecisions.Shared;
4、Pull模式下使用水晶報表
1）創建rpt文件
2）拖放CrystalReportViewer
3）綁定
5、讀取水晶報表文件
private
void ReadCRV(cryatalReportViewer crv)
{
openFileDialog dlg=new
OpenFileDialog();
dlg.Title="打開水晶報表文件";
dlg.Filter="水晶報表文件(*.rpt)|*.rpt|所有文件|*.*";
if(dlg.showDialog()==DialogResult.OK)
{
crv.ReportSource=dlg.FileName;
}
}
6.
B/S下讀取報表的文件
private void ReadCRV(cryatalReportViewer crv,File
file)
{
string
strName=file.PostedFile.FileName;
if(strName.Trim()!="")
{
crv.ReportSource=strName
Session["fileName"]=strName;
}
}
在B/S中要防止數據源的丟失
priavte
void Page_Load(object sender,System.EventArgs
e)
{
if(Session["fileName"]!=null)
{
crv.ReportSource=Session["fileName"].ToString();
}
}
7.
假如直接從數據庫中讀取數據，采用PULL模式可能出現錯誤（登錄的用戶名和密碼不對）
private void
ReadCRV(CrystalReportViewer crv,CrystalReport cr)
{
ReportDocument
reportDoc=new
ReportDocument();
reportDoc.Load(Server.MapPath(cr));//要加載的rpt文件的名字
//解決登錄的問題
TableLogOnInfo
logonInfo = new TableLogOnInfo();
foreach(Table tb in
ReportDoc.Database.Tables)
{
logonInfo=tb.LogOnInfo;
logonInfo.ConnectionInfo.ServerName="(loacl)";
logonInfo.ConnectionInfo.DatabaseName="Pubs";
logonInfo.ConnectionInfo.UserId="sa";
logonInfo.ConnectionInfo.Password="";
tb.ApplyLogOnInfo(logonInfo);
}
crv.ReportSource=reportDoc;
