copied!<p>It is much easier to run the process directly instead of using creating a batch file that you later execute since you lose some control since you are using a batch script layer.</p> <p>Use this code instead:</p> <pre><code> /// <summary> /// Execute external process. /// Block until process has terminated. /// Capture output. /// </summary> /// <param name="binaryFilename"></param> /// <param name="arguments"></param> /// <param name="currentDirectory"></param> /// <param name="priorityClass">Priority of started process.</param> /// <returns>stdout output.</returns> public static string ExecuteProcess(string binaryFilename, string arguments, string currentDirectory, ProcessPriorityClass priorityClass) { if (String.IsNullOrEmpty(binaryFilename)) { return "no command given."; } Process p = new Process(); p.StartInfo.FileName = binaryFilename; p.StartInfo.Arguments = arguments; p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.UseShellExecute = false; if (!String.IsNullOrEmpty(currentDirectory)) p.StartInfo.WorkingDirectory = currentDirectory; p.StartInfo.CreateNoWindow = false; p.Start(); // Cannot set priority process is started. p.PriorityClass = priorityClass; // Must have the readToEnd BEFORE the WaitForExit(), to avoid a deadlock condition string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); if (p.ExitCode != 0) { throw new Exception(String.Format("Process '{0} {1}' ExitCode was {2}", binaryFilename, arguments, p.ExitCode)); } //string standardError = p.StandardError.ReadToEnd(); //if (!String.IsNullOrEmpty(standardError)) //{ // throw new Exception(String.Format("Process '{0} {1}' StandardError was {2}", // binaryFilename, // arguments, // standardError)); //} return output; } </code></pre> <p>I use it in a number of projects and it works like a charm.</p> <p>If you HAVE to go the batch script route, make sure that the batch script set exitcode properly.</p>
