c# - User32的ShowWindow不能按预期运行

我正在使用User32中的ShowWindow方法向用户隐藏窗口（cmd.exe）（主要是为了防止他们关闭窗口）。当用户打开表单时，将启动并隐藏该过程，然后在关闭表单时将其杀死。但是，再次打开表单时，它不会隐藏窗口（有时不是第一次），有人可以帮我吗？

    [DllImport("User32")]
    private static extern int ShowWindow(int hwnd, int nCmdShow);   //this will allow me to hide a window

    public ConsoleForm(Process p) {
        this.p = p;
        p.Start();
        ShowWindow((int)p.MainWindowHandle, 0);   //0 means to hide the window. See User32.ShowWindow documentation SW_HIDE

        this.inStream = p.StandardInput;
        this.outStream = p.StandardOutput;
        this.errorStream = p.StandardError;

        InitializeComponent();

        wr = new watcherReader(watchProc);
        wr.BeginInvoke(this.outStream, this.txtOut, null, null);
        wr.BeginInvoke(this.errorStream, this.txtOut2, null, null);
    }

    private delegate void watcherReader(StreamReader sr, RichTextBox rtb);
    private void watchProc(StreamReader sr, RichTextBox rtb) {
        string line = sr.ReadLine();
        while (line != null && !stop && !p.WaitForExit(0)) {
            //Console.WriteLine(line);
            line = stripColors(line);
            rtb.Text += line + "\n";

            line = sr.ReadLine();
        }
    }

    public void start(string[] folders, string serverPath) {

        this.inStream.WriteLine("chdir C:\\cygwin\\bin");
        //this.inStream.WriteLine("bash --login -i");
        this.inStream.WriteLine("");
    }

    private void ConsoleForm_FormClosed(object sender, FormClosedEventArgs e) {
        this.stop = true;
        try {
            this.p.Kill();
            this.p.CloseMainWindow();
        } catch (InvalidOperationException) {
            return;
        }
    }

最佳答案

这样会更容易：

public ConsoleForm(Process p) {
        this.p = p;
        p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        p.StartInfo.CreateNoWindow = true;
        p.Start();

        this.inStream = p.StandardInput;
        this.outStream = p.StandardOutput;
        this.errorStream = p.StandardError;

        InitializeComponent();

        wr = new watcherReader(watchProc);
        wr.BeginInvoke(this.outStream, this.txtOut, null, null);
        wr.BeginInvoke(this.errorStream, this.txtOut2, null, null);
    }
