在DataReceivedEventHandler中获取Process.ID

问题描述

是否可以从DataReceivedEventHandler内部确定进程ID?

主代码启动多个进程，我需要确定哪个进程生成了DataReceivedEvent.

Hi,

Is it possible to determine the process id from within a DataReceivedEventHandler?

The main code launches multiple processes and I need to determine which process generated the DataReceivedEvent.

Process process = new Process();
            
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.FileName = Application.StartupPath + @"\RTMPdump\rtmpdump.exe";
process.StartInfo.Arguments = "-r \"" + StreamLoc + "\" -o \"" + fileName + ''"'';
if (process.Start() == true)
{
    process.OutputDataReceived += new DataReceivedEventHandler(ProcessDataReceived);
    process.ErrorDataReceived += new DataReceivedEventHandler(ProcessDataReceived);
    process.Exited += new EventHandler(ProcessExited);

    process.BeginOutputReadLine();
    process.BeginErrorReadLine();
}

void ProcessDataReceived(object sendingProcess, DataReceivedEventArgs outLine)
{
    if (InvokeRequired)
    {
        Invoke(new InvokedExecution(delegate()
        {
            if (!String.IsNullOrEmpty(outLine.Data))
            {
                // unfortunate this  \/   \/  does not work...
                textBox1.Text = outLine.ProcessID.ToString() + outLine.Data.ToString();
            }
        }));
    }
    else
    {
        if (!String.IsNullOrEmpty(outLine.Data))
        {
            //textBox1.Text = outLine.ProcessID.ToString() + outLine.Data.ToString();
        }
    }
}

有什么想法吗?

预先感谢.

Any ideas?

Thanx in advance.

推荐答案

Process proc = sendingProcess as Process;
string r = proc.Id.ToString();
