I converted the code to c# then I got an error message

 CS0118: 'uploadedFiles' is a 'variable' but is used like a 'method'

Source Error:
Line 21:             HttpPostedFile userPostedFile = uploadedFiles(i);
 string filepath = "C:\\Uploads";
        HttpFileCollection uploadedFiles = Request.Files;
        int i = 0;
        while (!(i == uploadedFiles.Count))
        {
            HttpPostedFile userPostedFile = uploadedFiles(i);
            try
            {
                if ((userPostedFile.ContentLength > 0))
                {
                    Label1.Text += "<u>File #" + (i + 1) + "</u><br>";

                    userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName));

                }
            }
            catch (Exception ex)
            {
                Label1.Text += "Error:<br>" + ex.Message;
            }
            i += 1;
