Question

I want the user to upload a file and save it to a stream.

Here is the code so far:

 private void Submit_ServerClick(object sender, System.EventArgs e)
        {


               fn = System.IO.Path.GetFileName(File1.PostedFile.FileName);

        }

you could do like this

  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;
  }
}

i hope it will helps you…
