I'm using the image upload tool uploadify in a webmatrix project. therefore, I have a webhandler which also creates a directory for every upload. Now I need the value of this created folder posted back on my site. Could you pleas help me with this. The webhandler looks like this: 

<%@ WebHandler Language="C#" Class="Upload" %>

using System;
using System.Web;
using System.IO;

public class Upload : IHttpHandler {

public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Expires = -1;
try
{
HttpPostedFile postedFile = context.Request.Files["Filedata"];

string savepath = "";
var dirName = string.Format("{0:yyyyMMdd_hhmmss}", DateTime.Now);
savepath = Path.Combine(@"D:\VisualStudio\Websites\AppHome\uploads\", dirName);
string filename = postedFile.FileName;
if (!Directory.Exists(savepath))
Directory.CreateDirectory(Path.Combine(@"D:\VisualStudio\Websites\AppHome\uploads\", dirName));

postedFile.SaveAs(savepath + @"\" + filename);
context.Response.Write(dirName + "/" + filename);
context.Response.StatusCode = 200;
context.Response.Write(dirName);
}
catch (Exception ex)
{
context.Response.Write("Error: " + ex.Message);
}
}

public bool IsReusable {

return false;
}
}
