如何使用POST在HTTP服務器上上傳文件？

我想使用POST上傳HTTP服務器上的文件，但是當我打電話時給出錯誤 req.GetResponse（）;在客戶端代碼如何使用POST在HTTP服務器上上傳文件？

遠程服務器返回錯誤：（405）方法不允許。

客戶端代碼

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代碼

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()); 
     } 
    } 

}

在服務器端的代碼我寫這些日誌來跟蹤如果在該行的任何錯誤或錯誤。

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

到

req.Method = "POST";

，然後再試一次。
