Here is what I use to start processes from calling applications. Since you are calling it from a web-app you are going to need to make sure you have appropriate permissions.

        Process         proc                = new Process();
        StringBuilder   sb                  = new StringBuilder();
        string[]        aTarget             = target.Split(PATH_SEPERATOR); 
        string          errorMessage;
        string          outputMessage;

        foreach (string parm in parameters)
        {
            sb.Append(parm + " ");
        }

        proc.StartInfo.FileName                 = target;
        proc.StartInfo.RedirectStandardError    = true;
        proc.StartInfo.RedirectStandardOutput   = true;
        proc.StartInfo.UseShellExecute          = false;
        proc.StartInfo.Arguments                = sb.ToString();

        proc.Start();

        proc.WaitForExit
            (
                (timeout <= 0)
                ? int.MaxValue : (int)TimeSpan.FromMinutes(timeout).TotalMilliseconds
            );


        errorMessage    = proc.StandardError.ReadToEnd();
        proc.WaitForExit();

        outputMessage   = proc.StandardOutput.ReadToEnd();
        proc.WaitForExit();

You'll also need to check to make sure that the account the Web application is running under has the appropriate permissions to execute the program.

You're probably trying to process a file that is in a different folder.

If so, you need to pass the full path of the file, like this:

Process.Start(@"C:\DocUpload\ConsoleApplication1.exe", 
              Path.Combine(@"C:\path\to\folder", TextBox1.Text));
