  When I pass Response.OutputStream as a readStream parameter to this method it is giving "Specified method is not supported." error in readStream.Read() method. I was trying to save a Response.OutputStream to a file. Please help.

  Here's an example that's optimized for getting copying a file from an ASP.NET FileUpload control and keeping it's path.

  string filePath = uploadFile(fileUploadControl.FileContent);
  
  private string uploadFile(Stream serverFileStream)
  {
      string filename = ConfigurationManager.AppSettings["FileUploadTempDir"] + 
          DateTime.Now.ToString("yyyyMMddhhmm") + "_" + 
          Customer.GetCustomerName(CustomerId).Replace(" ", "_") + ".txt";
  
      try
      {
          int length = 256;
          int bytesRead = 0;
          Byte[] buffer = new Byte[length];
  
          // write the required bytes
          using (FileStream fs = new FileStream(filename, FileMode.Create))
          {
              do
              {
                  bytesRead = serverFileStream.Read(buffer, 0, length);
                  fs.Write(buffer, 0, bytesRead);
              }
              while (bytesRead == length);
          }
  
          serverFileStream.Dispose();
          return filename;
      }
      catch (Exception ex)
      {
          lblErrorMessage.Text += "An unexpeded error occured uploading the file. " + ex.Message;
          return string.Empty;
      }
  
  }
