我想上传使用POST HTTP服务器上的文件,但是当我把它给了使用POST在HTTP服务器上传文件给HttpFileCollection 0?

uploadFile.Count = 0 AMD不会进入if语句。文件路径是正确的。

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 = "POST"; // 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"); 
      LogInFile(uploadFile.Count.ToString()); 
      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。

在服务器代码,它给uploadFile.Count = 0和 不走在调试模式下的客户端代码执行成功,但给页面

这个消息您可以从服务器/客户端代码中看到的..有没有涉及数据库。

请张贴您的html表单。也登录失败的sa是asp.net无法登录到你的db – 2012-04-25 05:13:17

你可以从代码中看到没有涉及数据库..或DB访问代码甚至 – Azhar 2012-04-25 06:32:31

那么你发布的错误是数据库相关。也许代码在项目中的其他地方。也许global.asax? – 2012-04-25 07:27:40
