一行运行命令:

new Process() { StartInfo = new ProcessStartInfo("echo", "Hello, World") }.Start();

以最短的可读代码量读取命令输出:

    var cliProcess = new Process() {
        StartInfo = new ProcessStartInfo("echo", "Hello, World") {
            UseShellExecute = false,
            RedirectStandardOutput = true
        }
    };
    cliProcess.Start();
    string cliOut = cliProcess.StandardOutput.ReadToEnd();
    cliProcess.WaitForExit();
    cliProcess.Close();

一行运行命令:

new Process() { StartInfo = new ProcessStartInfo("echo", "Hello, World") }.Start();

        }
    };
    cliProcess.Start();

我发现还有一个有用的参数，我用它来消除流程窗口

pProcess.StartInfo.CreateNoWindow = true;

这有助于从用户完全隐藏黑色控制台窗口，如果这是你想要的。

只是为了好玩，这里是我完整的获得PYTHON输出的解决方案-在单击按钮下-带有错误报告。只需添加一个名为“butPython”的按钮和一个名为“llHello”的标签…

    private void butPython(object sender, EventArgs e)
    {
        llHello.Text = "Calling Python...";
        this.Refresh();
        Tuple<String,String> python = GoPython(@"C:\Users\BLAH\Desktop\Code\Python\BLAH.py");
        llHello.Text = python.Item1; // Show result.
        if (python.Item2.Length > 0) MessageBox.Show("Sorry, there was an error:" + Environment.NewLine + python.Item2);
    }

    public Tuple<String,String> GoPython(string pythonFile, string moreArgs = "")
    {
        ProcessStartInfo PSI = new ProcessStartInfo();
        PSI.FileName = "py.exe";
        PSI.Arguments = string.Format("\"{0}\" {1}", pythonFile, moreArgs);
        PSI.CreateNoWindow = true;
        PSI.UseShellExecute = false;
        PSI.RedirectStandardError = true;
        PSI.RedirectStandardOutput = true;
        using (Process process = Process.Start(PSI))
            using (StreamReader reader = process.StandardOutput)
            {
                string stderr = process.StandardError.ReadToEnd(); // Error(s)!!
                string result = reader.ReadToEnd(); // What we want.
                return new Tuple<String,String> (result,stderr); 
            }
    }

您可以使用Process类启动任何命令行程序，并使用您创建的流阅读器(基于字符串或内存位置)设置Process实例的StandardOutput属性。流程完成后，您就可以在流上执行所需的任何diff。

// Start the child process.
 Process p = new Process();
 // Redirect the output stream of the child process.
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.FileName = "YOURBATCHFILE.bat";
 p.Start();
 // Do not wait for the child process to exit before
 // reading to the end of its redirected stream.
 // p.WaitForExit();
 // Read the output stream first and then wait.
 string output = p.StandardOutput.ReadToEnd();
 p.WaitForExit();
