SWFUpload asp.net返回上传文件的新文件名

Question

我试图在我的页面上实现SWFUpload上传图片。文件路径存储在一个唯一的ID作为关键字的表中，该文件以一个新的文件名存储在服务器上。我需要返回id或文件名，以便我稍后需要时可以访问这些信息。这是可能的，它是如何完成的？也许我可以更新一个asp：标签？

我有以下代码：

upload.aspx.cs （我还没有实现的数据库中保存尚为我想知道这是可能的第一）

 protected void Page_Load(object sender, EventArgs e) 
    { 
     try 
     { 
      // Get the data 
      HttpPostedFile postedfile = Request.Files["Filedata"]; 

      int n = 0; 
      string fullPath; 

      while (true) 
      { 
       fullPath = Server.MapPath("Img\\") + n.ToString() + RemoveSpecialChars(postedfile.FileName); 
       if (File.Exists(fullPath)) 
       { 
        n++; 
       } 
       else 
       { 
        postedfile.SaveAs(fullPath); 
        break; 
       } 
      } 

     } 
     catch 
     { 
      // If any kind of error occurs return a 500 Internal Server error 
      Response.StatusCode = 500; 
      Response.Write("An error occured"); 
      Response.End(); 
     } 
     finally 
     { 

      Response.End(); 
     } 
    } 

默认。 ASPX

    <script type="text/javascript" src="Scripts/swfupload.js"></script>

     var swfu; 
     window.onload = function() { 
      swfu = new SWFUpload({

     }

的Default.aspx

      <span id="spanButtonPlaceholder"></span> 
     </div>

    </div> 

谢谢。

我找到了解决办法： 如果我往里handlers.js（由SWFUpload的提供）我能赶上什么从upload.aspx.cs

内upload.aspx.cs写返回：

protected void Page_Load(object sender, EventArgs e) 
    { 
     try 
     { 
      // Get the data 
      HttpPostedFile postedfile = Request.Files["Filedata"]; 

      Response.Write((postedfile.FileName); //Returns filename to javascript 

     } 
     catch 
     { 
      // If any kind of error occurs return a 500 Internal Server error 
      Response.StatusCode = 500; 
      Response.Write("An error occured"); 
      Response.End(); 
     } 
     finally 
     { 

      Response.End(); 
     } 
    } 
} 

内handler.js（从演示页面下载）替换为uploadSuccess：

function uploadSuccess(file, serverData) { 
try { 

    alert(serverData); 

    addImage("thumbnail.aspx?id=" + serverData); 

    var progress = new FileProgress(file, this.customSettings.upload_target); 

    progress.setStatus("Thumbnail Created."); 
    progress.toggleCancel(false); 


} catch (ex) { 
    this.debug(ex); 
} 
}
