.bat 处理错误码

某些命令只会返回error level,而要添加互操作性，.bat文件的返回值，exit code应该最后指定，那么需要，在这个单行的命令后面单个添加处理error level

的语句，最后再做统一的抛出处理，一个robo copy，批量拷贝，很实用的例子，可以作为参考，以下命令通过测试

@echo off
ROBOCOPY c:\a c:\d /MIR /LOG:c:\d\log1.txt
if %ERRORLEVEL% GEQ 8 echo error encountered errorlevel:%errorlevel%  & goto throw
ROBOCOPY c:\b c:\c /MIR /LOG:c:\c\log2.txt
:throw
if %ERRORLEVEL% GEQ 16 echo ***FATAL ERROR*** & goto end
if %ERRORLEVEL% EQU 15 echo OKCOPY + FAIL + MISMATCHES + XTRA & goto end
if %ERRORLEVEL% EQU 14 echo FAIL + MISMATCHES + XTRA & goto end
if %ERRORLEVEL% EQU 13 echo OKCOPY + FAIL + MISMATCHES & goto end
if %ERRORLEVEL% EQU 12 echo FAIL + MISMATCHES& goto end
if %ERRORLEVEL% EQU 11 echo OKCOPY + FAIL + XTRA & goto end
if %ERRORLEVEL% EQU 10 echo FAIL + XTRA & goto end
if %ERRORLEVEL% EQU 9 echo OKCOPY + FAIL & goto end
if %ERRORLEVEL% EQU 8 echo FAIL & goto end
if %ERRORLEVEL% EQU 7 echo OKCOPY + MISMATCHES + XTRA & goto end
if %ERRORLEVEL% EQU 6 echo MISMATCHES + XTRA & goto end
if %ERRORLEVEL% EQU 5 echo OKCOPY + MISMATCHES & goto end
if %ERRORLEVEL% EQU 4 echo MISMATCHES & goto end
if %ERRORLEVEL% EQU 3 echo OKCOPY + XTRA & goto end
if %ERRORLEVEL% EQU 2 echo XTRA & goto end
if %ERRORLEVEL% EQU 1 echo OKCOPY & goto end
if %ERRORLEVEL% EQU 0 echo No Change & goto end
:end
if %ERRORLEVEL% GEQ 8 exit %ErrorLevel%
exit 0

a sample call in c# with exitcode handling

void Main()
{

Process processer = new Process();
                    processer.StartInfo.FileName = @"c:\a\testrobocopy.bat";
                    processer.StartInfo.Arguments = null;

                    processer.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                    processer.StartInfo.RedirectStandardOutput = true;
                    processer.StartInfo.RedirectStandardError = true;
                    processer.StartInfo.UseShellExecute = false;
                    processer.StartInfo.CreateNoWindow = true;
                    processer.EnableRaisingEvents = true;

                    processer.OutputDataReceived += new DataReceivedEventHandler(OutputDataReceived);
                    processer.ErrorDataReceived += new DataReceivedEventHandler(ErrorDataReceived);

                    processer.Start();
                    processer.BeginOutputReadLine();
                    processer.BeginErrorReadLine();
					processer.WaitForExit();
					Console.WriteLine (processer.ExitCode);
	//Marshal.ThrowExceptionForHR(Marshal.GetLastWin32Error());
}

private void ErrorDataReceived(object sendingProcess,
            DataReceivedEventArgs outLine)
        {
            if (!String.IsNullOrEmpty(outLine.Data))
            {
                Console.WriteLine ("error:"+outLine.Data);
            }
        }
