Question

我在Windows命令提示符下面运行命令，它提供如下输出

C:\>logman.exe FabricTraces | findstr Root
Root Path: C:\ProgramData\Windows Fabric\Fabric\log\Traces\

现在，我试图在C＃程序中模仿相同的内容，并希望将输出（C:\ProgramData\Windows Fabric\Fabric\log\Traces\）捕获到变量中。

如何做到这一点，这是我尝试过的代码，

Process P = Process.Start("logman.exe", "FabricTraces | findstr Root");
            P.WaitForExit();
            var result = P.ExitCode;

这样的事情：

private void StartProcess()
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();

    process.StartInfo.FileName               = /* path + binary */;
    process.StartInfo.Arguments              = /* arguments */;
    process.StartInfo.WorkingDirectory       = /* working directory */;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError  = true;
    process.StartInfo.UseShellExecute        = false;
    process.StartInfo.CreateNoWindow         = true;

    process.OutputDataReceived += Process_OutputDataReceived;
    process.ErrorDataReceived += Process_ErrorDataReceived;

    process.Start();

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

    process.WaitForExit();
}

private void Process_ErrorDataReceived(object sender, System.Diagnostics.DataReceivedEventArgs e)
{
    /* e.Data will contain string with error message */
}

private void Process_OutputDataReceived(object sender, System.Diagnostics.DataReceivedEventArgs e)
{
    /* e.Data will contain string with output */
}

如何将Process的输出捕获到C＃变量中？
