After tried calling paexec from C# program, it can't capture any stderr, tested my program on psexec, it can capture stderr, however for paexec, if runs from a command shell, it can see the stderr, but can't see it appeared on my program. Is this fault on paexec?
void Main() { var cmdargs =@"machine c:windowssystem32inetsrvappcmd list apppool"; for(int i=0;i<10;i++) { Debug.WriteLine("Trial #{0}",i); psexec(cmdargs, true); } }
// ISSUE: if paexec used, nothing from stderr is captured at all (stdout seems ok) // (with psexec, stderr is captured, but due to other reasons psexec fails) string pexec() {return "paexec.exe";} // Define other methods and classes here
void psexec(string cmdargs, bool showOutput=true)
{
// uses method described in http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standardoutput.aspx
// Read at least one stream asynchronously to avoid deadlock condition
StringBuilder outputTxt=new StringBuilder();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName =pexec();
startInfo.Arguments = cmdargs;
Debug.WriteLine(cmdargs);
startInfo.UseShellExecute = false;
startInfo.RedirectStandardError = true;
startInfo.RedirectStandardOutput = true;
startInfo.CreateNoWindow = true;
Process process = new Process();
process.StartInfo = startInfo;
process.OutputDataReceived +=
new DataReceivedEventHandler(
(object proc,DataReceivedEventArgs outline)=>{
if (!String.IsNullOrEmpty(outline.Data))
outputTxt.Append(Environment.NewLine+outline.Data);
});
process.Start();
process.BeginOutputReadLine();
string errTxt=process.StandardError.ReadToEnd();
process.WaitForExit();
Debug.WriteLine("Process exit code: {0}",process.ExitCode);
process.Close();
if (showOutput){
Debug.WriteLine("ERR:"+errTxt);
Debug.WriteLine("OUT:"+outputTxt);
}
}
