是否有事件告诉我进程正在等待输入?

I am processing a Tex file by starting a Process like this one:

我正在处理一个Tex文件，启动了这样一个过程:

process p1 = new Process();
p1.StartInfo.FileName = "C:\\texlive\\2012\\bin\\win32\\pdflatex.exe";
p1.StartInfo.Arguments = FileName;
p1.consuleProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p1.consuleProcess.StartInfo.CreateNoWindow = true;
p1.consuleProcess.StartInfo.RedirectStandardOutput = true;
p1.consuleProcess.StartInfo.UseShellExecute = false;
p1.consuleProcess.StartInfo.RedirectStandardInput = true;
p1.Start();
p1.consuleProcess.BeginOutputReadLine();
p1.consuleProcess.OutputDataReceived += new DataReceivedEventHandler(p1_OutputDataReceived);

I display the output strings in a TextBox by handling OutputDataReceived event.

我通过处理OutputDataReceived事件在文本框中显示输出字符串。

If there were an error in the Tex file, a line should be written in StandardInput. I think there is no event that can tell me, when the process is waiting for an input; So I thought, I can check OutputDataReceived event to see when the condition: e.Data == "?" is true. But, the problem is that the StandardInput needs an input, just before firing OutputDataReceived event with e.Data=="?"

如果Tex文件中有错误，应该用StandardInput编写一行。我认为没有任何事件可以告诉我，当进程在等待输入;所以我想，我可以检查OutputDataReceived事件，看看什么时候条件:e。数据= "?"是真的。但是，问题是StandardInput需要一个输入，就在用e.Data= "?"触发OutputDataReceived事件之前。

So, what can I do to see when the process is waiting for an input?

那么，当进程在等待输入时，我能做些什么呢?

thanks.

谢谢。

Not sure if this is what you mean but are you after something like

不确定这是不是你的意思，但你是在追求类似的东西吗

p1.WaitForInputIdle(NumberofMilisecondstoWait)

Update:

更新:

Maybe something like this

也许是这样的

  public void test()
        {
            p1.OutputDataReceived += new DataReceivedEventHandler(p1_OutputDataReceived);
        }

        void p1_OutputDataReceived(object sender, DataReceivedEventArgs e)
        {
            throw new NotImplementedException();
        }
