无论如何,是否可以重定向生成进程的标准输出并在发生时捕获它。我所看到的一切都只是在该过程完成后执行 ReadToEnd 。我希望能够在打印时获得输出。
Edit:
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);
}
Use Process.OutputDataReceived http://msdn.microsoft.com/en-us/library/system.diagnostics.process.outputdatareceived.aspx来自流程的事件,以接收您需要的数据。
例子:
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))
{
....
}
}
