Can Not Upload One File at Third Times

[hu tao]

I am working in a project,I have used the RadUpload,the code of upload file in my project is follow:

protected void Submit_Click(object sender, EventArgs e)
    {
        if (RadUpload1.UploadedFiles.Count > 0)
        {
            System.Threading.Thread.Sleep(3000);
            try
            {
                string targetFolder = Server.MapPath(@"UpLoadFile\Project");
                string targetFileName = string.Empty;
                foreach (UploadedFile files in RadUpload1.UploadedFiles)
                {
                    int counter = 1;
                    string fileName = files.GetName();
                    string fileName1 = files.GetNameWithoutExtension() + counter.ToString() + files.GetExtension();
                    targetFileName = System.IO.Path.Combine(targetFolder, fileName);
                    while (System.IO.File.Exists(targetFileName))
                    {
                        targetFileName = System.IO.Path.Combine(targetFolder, fileName1);
                        fileName = fileName1;
                        counter++;
                    }
                    files.SaveAs(targetFileName);

                    //here,I insert the file info into DB;
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
       }
    }

First,I upload a file "test.txt" into server, then I upload the file "test.txt" second times, in server it's name is renamed as "test1.txt",this project works well, but when I upload the file "test.txt" third times , the RadProgressArea's Elapsed time and Speed run all the time, the radupload can not upload this file, I try this action several times ,but can not work well too.
I think my code where rename the upload file can not work well,but it seems that my code is correct.
What can I do in this situation?
Are there any settings about RadUpload to solve my question?

Thanks

Hello hu tao,

Your code is incorrect, please move the

string fileName1 = files.GetNameWithoutExtension() + counter.ToString() + files.GetExtension();

line inside the while loop. So, the correct version should look like this:

protected void Submit_Click(object sender, EventArgs e)
   {
       if (RadUpload1.UploadedFiles.Count > 0)
       {
           System.Threading.Thread.Sleep(3000);
           try
           {
               string targetFolder = Server.MapPath(@"UpLoadFile\Project");
               string targetFileName = string.Empty;
               foreach (UploadedFile files in RadUpload1.UploadedFiles)
               {
                   int counter = 1;
                   string fileName = files.GetName();

                   targetFileName = System.IO.Path.Combine(targetFolder, fileName);
                   while (System.IO.File.Exists(targetFileName))
                   {
                       string fileName1 = files.GetNameWithoutExtension() + counter.ToString() + files.GetExtension();
                       targetFileName = System.IO.Path.Combine(targetFolder, fileName1);
                       fileName = fileName1;
                       counter++;
                   }
                   files.SaveAs(targetFileName);

                   //here,I insert the file info into DB;
               }
           }
           catch (Exception ex)
           {
               throw ex;
           }
       }
   }

This should fix the problems you experience.
