从c＃读取windows批处理文件的输出

Question

我有一个要求，我必须使用Windows批处理文件检查文件的大小，并从c＃代码中读取输出

批处理脚本

@echo off
set maximumbytesize=1000
setlocal EnableDelayedExpansion
for /F  %%a in ('dir /B D:\test_batch_files') do (
  set name=%%a
  set size=%%~za
  if  !size! GTR !maximumbytesize! (
    echo greater
  ) ELSE (
    echo smaller
  )
)

c＃代码获取输出：

 Process p = new Process();
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.FileName = "D:\\test_batch_files\\GetFileSizeInDirectory.bat";
            //ConfigurationManager.AppSettings["BatchScriptPath"].ToString();                   
            p.Start();
            StreamReader myStreamReader = p.StandardOutput;
             myString = myStreamReader.ReadToEnd();
            p.WaitForExit();

运行批处理的输出应该是（从cmd运行）：

smaller
smaller
smaller
greater
smaller
smaller
smaller
smaller
smaller
smaller

c＃

的输出

smaller
smaller
smaller
smaller
smaller
smaller
smaller
smaller
smaller
smaller
