System.Net命名空間下的FtpWebRequest類實現了ftp協議的.Net實現。
- FtpWebRequest.KeepAlive指定在請求完成后服務器是否要馬上關閉連接
- FtpWebRequest.UseBinary 指定文件以二進制方式傳輸
- FtpWebRequest.Method設置ftp的命令
- WebRequestMethods.Ftp.UploadFile是上傳文件的命令
使用FtpWebRequest對象上傳文件時,需要向GetRequestStream方法返回的Stream中寫入數據。
需要引用如下命名空間
using System.Net; using System.IO;
FTP上傳文件代碼實現:
public void ftpfile(string ftpfilepath, string inputfilepath) { string ftphost = "127.0.0.1"; //here correct hostname or IP of the ftp server to be given string ftpfullpath = "ftp://" + ftphost + ftpfilepath; FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath); ftp.Credentials = new NetworkCredential("userid", "password"); //userid and password for the ftp server to given ftp.KeepAlive = true; ftp.UseBinary = true; ftp.Method = WebRequestMethods.Ftp.UploadFile; FileStream fs = File.OpenRead(inputfilepath); byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); fs.Close(); Stream ftpstream = ftp.GetRequestStream(); ftpstream.Write(buffer, 0, buffer.Length); ftpstream.Close(); }
調用方法:
ftpfile(@"/testfolder/testfile.xml", @"c:\testfile.xml");
