从Winforms控制cmd.exe [英] Controlling cmd.exe from Winforms

问题描述

问题：我想从winforms中控制cmd.exe。

Question: I want to control cmd.exe from winforms.

我不是说在单个进程中使用Startupinfo停止每个命令，然后停止。

I DO NOT mean every command in a single process, with startupinfo, and then stop.

例如，我的意思是启动（My）SQL或GDB命令提示符，发送命令，接收答案，发送下一个命令，接收下一个答案，停止SQL命令提示符


退出过程。

I mean for example start the (My) SQL or GDB command prompt, send command, receive answer, send next command, receive next answer, stop SQL command prompt
exit process.

基本上我想在任何控制台应用程序的顶部编写GUI。

Basically I want to write a GUI on top of any console application.

我想将cmd.exe的输出重定向到一个文本字段，而输入来自另一个文本字段（按Enter / OK按钮）。

I want to have the output from cmd.exe redirected to a textfield, and the input coming from another textfield (on press enter/OK button).

我没有找到任何样品。
有办法吗？

I don't find any samples for this. Is there a way?

-编辑：
我认为这更像它，我创建了一个简单的表单，2个文本框和3个按钮。
第一个文本框用于输入命令，第二个（多行）显示结果。

- I think this is more like it, I created a simple form, 2 textboxes and three buttons. First textbox is for command entry, the second (multiline), displays the result.

第一个按钮执行命令，第二个按钮更新结果（因为结果是异步读取的）

The first button executes the command, the second button updates the result (because results are read async)

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        private static StringBuilder cmdOutput = null;
        Process cmdProcess;
        StreamWriter cmdStreamWriter;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            cmdOutput = new StringBuilder("");
            cmdProcess = new Process();

            cmdProcess.StartInfo.FileName = "cmd.exe";
            cmdProcess.StartInfo.UseShellExecute = false;
            cmdProcess.StartInfo.CreateNoWindow = true;
            cmdProcess.StartInfo.RedirectStandardOutput = true;

            cmdProcess.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler);
            cmdProcess.StartInfo.RedirectStandardInput = true;
            cmdProcess.Start();

            cmdStreamWriter = cmdProcess.StandardInput;
            cmdProcess.BeginOutputReadLine();
        }

        private void btnExecute_Click(object sender, EventArgs e)
        {
            cmdStreamWriter.WriteLine(textBox2.Text);
        }

        private void btnQuit_Click(object sender, EventArgs e)
        {
            cmdStreamWriter.Close();
            cmdProcess.WaitForExit();
            cmdProcess.Close();
        }

        private void btnShowOutput_Click(object sender, EventArgs e)
        {
            textBox1.Text = cmdOutput.ToString();
        }

        private static void SortOutputHandler(object sendingProcess,
            DataReceivedEventArgs outLine)
        {
            if (!String.IsNullOrEmpty(outLine.Data))
            {
                cmdOutput.Append(Environment.NewLine + outLine.Data);
            }
        }
    }
}

在在屏幕快照中，您可以看到我输入了cd\命令来更改目录，并在该目录中执行了下一个命令（dir）。

In the screenshot you can see that I entered the cd\ command to change directory and the next command executed in this directory (dir).
