客戶端：先創建一個winform窗體的應用程序項目
項目結構
winform窗體布局分配好，需要一個文本框，兩個按鈕，一個進度條，幾個label標簽
具體如下：
客戶端代碼如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Net;

namespace UpFileClient
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string filePath = "";
private void btnSelect_Click(object sender, EventArgs e)
{
//創建文件彈出選擇窗口（包括文件名）對象
OpenFileDialog ofd = new OpenFileDialog();
//判斷選擇的路徑
if (ofd.ShowDialog() == DialogResult.OK)
{
this.txtSoundPath.Text = ofd.FileName.ToString();
}
filePath = this.txtSoundPath.Text;
}
private void btnUpSound_Click(object sender, EventArgs e)
{
try {
//上傳服務器的地址（web服務）
string address = "http://localhost:28207/WebService/SaveFileWebForm.aspx";
//上傳后文件保存的名稱
string saveName = DateTime.Now.ToString("yyyyMMddHHmmss");
int count = UpSound_Request(address, filePath, saveName, this.progressBar1);
if (count > 0)
{
MessageBox.Show("上傳文件成功！");
}
else
{
MessageBox.Show("上傳文件失敗！");
}
}catch(Exception ex){
MessageBox.Show(""+ex.GetBaseException());
}
}

public int UpSound_Request(string address, string fileNamePath, string saveName, ProgressBar progressBar)
{

//要上傳的文件

//二進制對象

//時間戳
string strBoundary = "----------" + DateTime.Now.Ticks.ToString("x");

string strPostHeader = sb.ToString();
byte[] postHeaderBytes = Encoding.UTF8.GetBytes(strPostHeader);
// 根據uri創建HttpWebRequest對象
HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create(new Uri(address));
httpReq.Method = "POST";
//對發送的數據不使用緩存
httpReq.AllowWriteStreamBuffering = false;
//設置獲得響應的超時時間（300秒）

while (size > 0)
{

offset += size;
progressBar.Value = (int)(offset * (int.MaxValue / length));
TimeSpan span = DateTime.Now - startTime;
double second = span.TotalSeconds;

}
//添加尾部的時間戳
postStream.Write(boundaryBytes, 0, boundaryBytes.Length);
postStream.Close();
//獲取服務器端的響應

}
finally

r.Close();
}

}
}
}
客戶端上傳文件的效果圖：
服務器端：
創建一個web mvc4項目，在創建一個webservice文件夾，在文件夾下創建一個SaveFileWebForm.axpx接口，
設置這個頁面為項目起始頁，打開這個頁面，右鍵查看代碼，編寫服務器端代碼，運行項目
項目結構：
客戶端上傳文件時，服務器端（SaveFileWebForm.axpx）需要訪問的到，（注：先運行服務器程序項目，在運行客戶端程序項目）
服務器端源碼：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace SaveFileWebService.WebService
{
public partial class SaveFileWebForm : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Request.Files.Count > 0)
{
try
{
//得到客戶端上傳的文件
HttpPostedFile file = Request.Files[0];
//服務器端要保存的路徑
string filePath = "D:\\Test\\" + file.FileName + ".mp3";
file.SaveAs(filePath);
//返回結果
Response.Write("Success");
}
catch
{
Response.Write("Error");
}
}
else
{
Response.Write("Error1");
}
}
}
}
服務器接收后文件如下圖：
