有没有办法重定向一个生成的进程的标准输出,并捕获它的发生.我所看到的一切只是在完成了一个ReadToEnd之后.我希望能够得到正在打印的输出.
编辑：
private void ConvertToMPEG()
{
// Start the child process.
Process p = new Process();
// Redirect the output stream of the child process.
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
//Setup filename and arguments
p.StartInfo.Arguments = String.Format("-y -i \"{0}\" -target ntsc-dvd -sameq -s 720x480 \"{1}\"",tempDir + "out.avi",tempDir + "out.mpg");
p.StartInfo.FileName = "ffmpeg.exe";
//Handle data received
p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
p.Start();
}
void p_OutputDataReceived(object sender,DataReceivedEventArgs e)
{
Debug.WriteLine(e.Data);
}
解决方法
从过程中使用
Process.OutputDataReceived事件,以接收所需的数据.
例：
var myProc= new Process();
...
myProc.StartInfo.RedirectStandardOutput = true;
myProc.OutputDataReceived += new DataReceivedEventHandler(MyProcOutputHandler);
...
private static void MyProcOutputHandler(object sendingProcess,DataReceivedEventArgs outLine)
{
// Collect the sort command output.
if (!String.IsNullOrEmpty(outLine.Data))
{
....
}
}
