如何使用POST在HTTP服务器上上传文件？

我想使用POST上传HTTP服务器上的文件，但是当我打电话时给出错误 req.GetResponse（）;在客户端代码如何使用POST在HTTP服务器上上传文件？

远程服务器返回错误：（405）方法不允许。

客户端代码

public partial class _Default : System.Web.UI.Page 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      string fileToUpload = Server.MapPath("~/Files/Ricky_Martin_Livin_la.mp3"); 
      string uploadUrl = "http://localhost/soundcheck/uploadfiles.aspx"; 
      //string uploadUrl = "http://10.0.2.2/musicapp/handle_upload.php"; 
      FileStream rdr = new FileStream(fileToUpload, FileMode.Open); 
      HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uploadUrl); 
      req.Method = "PUT"; // you might use "POST" 
      req.ContentLength = rdr.Length; 
      req.AllowWriteStreamBuffering = true; 

      Stream reqStream = req.GetRequestStream(); 

      byte[] inData = new byte[rdr.Length]; 

      // Get data from upload file to inData 
      int bytesRead = rdr.Read(inData, 0, int.Parse(rdr.Length.ToString())); 

      // put data into request stream 
      reqStream.Write(inData, 0, int.Parse(rdr.Length.ToString())); 

      rdr.Close(); 
      req.GetResponse(); 

      // after uploading close stream 
      reqStream.Close(); 
     } 
    }

Server代码

using System; 
using System.Collections; 
using System.IO; 
using System.Data; 
using System.Web; 
using System.Text; 
using System.Web.Security; 

public partial class uploadfiles : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     try 
     { 
      LogInFile("First"); 
      HttpFileCollection uploadFile = Request.Files; 
      LogInFile("Second"); 
      if (uploadFile.Count > 0) 
      { 
       HttpPostedFile postedFile = uploadFile[0]; 
       LogInFile("Thrid"); 
       System.IO.Stream inStream = postedFile.InputStream; 
       LogInFile("Forth"); 
       byte[] fileData = new byte[postedFile.ContentLength]; 
       LogInFile("Fifth"); 
       inStream.Read(fileData, 0, postedFile.ContentLength); 
       LogInFile("Sixth"); 
       postedFile.SaveAs(Server.MapPath("Data") + "\\" + postedFile.FileName); 
      }   
     } 
     catch (Exception ex) 
     { 
      StringBuilder sb = new StringBuilder(); 
      sb.AppendLine("Message : " +ex.Message); 
      sb.AppendLine("Source : " + ex.Source); 
      sb.AppendLine("StackTrace : " + ex.StackTrace); 
      sb.AppendLine("InnerException : " + ex.InnerException); 
      sb.AppendLine("ToString : " + ex.ToString()); 

      LogInFile(sb.ToString()); 
     } 
    } 
    public void LogInFile(string str) 
    { 
     StringBuilder sb = new StringBuilder(); 
     using (StreamReader sr = new StreamReader(Server.MapPath("Data") + "\\expfile.txt")) 
     {    
      sb.AppendLine("= = = = = ="); 
      sb.Append(sr.ReadToEnd()); 
      sb.AppendLine(); 
      sb.AppendLine(); 
     } 
     sb.AppendLine(str); 
     using (StreamWriter outfile = new StreamWriter(Server.MapPath("Data") + "\\expfile.txt")) 
     { 
      outfile.Write(sb.ToString()); 
     } 
    } 

}

在服务器端的代码我写这些日志来跟踪如果在该行的任何错误或错误。

req.Method = "PUT"; // you might use "POST"

到

req.Method = "POST";

，然后再试一次。
