在 C# 中使用 windows 形式鼠标左键的语音识别

Question

我正在尝试编码为 windows 形式的鼠标左键单击。当我说 "left click" 时，我想在屏幕上的任意位置 单击鼠标左键 。我已经尝试了一些代码，但它给出了错误这是代码：

public Form1()
    {
        InitializeComponent();


        this.KeyPreview = true;
        this.KeyDown += new    System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);


        var Form1 = new Form();
        Form1.Location = new Point(50, 50);

        Form1.AutoSize = true;
        Form1.Click += new EventHandler(Form1_Click);
        this.Controls.Add(Form1);
    }

    [System.Runtime.InteropServices.DllImport("user32.dll")]
    public static extern void mouse_event(int dwFlags, int dx, int dy, int  cButtons, int dwExtraInfo);

    public const int MOUSEEVENTF_LEFTDOWN = 0x02;
    public const int MOUSEEVENTF_LEFTUP = 0x04;


    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        SimulateLeftClick();
    }


    private void SimulateLeftClick()
    {
        int xpos = Cursor.Position.X;
        int ypos = Cursor.Position.Y;
        mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
        mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);
    }
case "left click":
                int xpos = Cursor.Position.X;
                int ypos = Cursor.Position.Y;
                mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
                mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);
                break;

   private void Form1_Click(object sender, EventArgs e)
    {

        MessageBox.Show("Left Click simulated");
    }

当我运行这个程序出错时 "Top-level control cannot be added to a control." 在 this.Controls.Add(Form1) 在上面的程序中。所以请任何人给我一个解决方案

顶级控件定义为不由另一个 Windows Forms 控件作为父级的父控件。通常，这是包含控件的最外层窗体。

在您的情况下，Form1 似乎是顶级控件。删除行：

 this.Controls.Add(Form1);
