使用 C# 控制另一个应用程序

Question

我需要通过模拟鼠标移动和键盘输入来控制其他应用程序。我如何在 C# 中实现这一点？甚至可能吗？

Answer 1

你看过WhiteTestStack吗？

示例代码：

Application application = Application.Launch("foo.exe");
Window window = application.GetWindow("bar", InitializeOption.NoCache);

Button button = window.Get<Button>("save");
button.Click();

我认为没有比这更好的了。该库由 ThoughtWorks 创建。

请参阅此页面上的“将击键发送到其他应用程序”：

您可以使用 p/invoke，我窃取了以下代码，用于在具有已知句柄的按钮上随机点击鼠标：

    [Flags]
    public enum MouseEventFlags
    {
        LEFTDOWN = 0x00000002,
        LEFTUP = 0x00000004,
        MIDDLEDOWN = 0x00000020,
        MIDDLEUP = 0x00000040,
        MOVE = 0x00000001,
        ABSOLUTE = 0x00008000,
        RIGHTDOWN = 0x00000008,
        RIGHTUP = 0x00000010
    }

    [StructLayout(LayoutKind.Sequential)]
    public struct Rectangle
    {
        public int X;
        public int Y;
        public int Width;
        public int Height;
    }

    private static void Click(IntPtr Handle)
    {
        lock (typeof(MouseAction))
        {
            Rectangle buttonDesign;

            GetWindowRect(Handle, out buttonDesign);
            Random r = new Random();

            int curX = 10 + buttonDesign.X + r.Next(100 - 20);
            int curY = 10 + buttonDesign.Y + r.Next(60 - 20);

            SetCursorPos(curX, curY);
            //Mouse Right Down and Mouse Right Up
            mouse_event((uint)MouseEventFlags.LEFTDOWN, curX, curY, 0, 0);
            mouse_event((uint)MouseEventFlags.LEFTUP, curX, curY, 0, 0);  
        }
    }

    [DllImport("user32.dll")]
    static extern bool SetCursorPos(int X, int Y);

    [DllImport("user32.dll")]
    private static extern void mouse_event(
        long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);

    [DllImport("user32.dll")]
    static extern bool GetWindowRect(IntPtr hWnd, out Rectangle rect);

您可以使用AutoIT，它是免费软件，它有一个可以导入C# (DllImport) 的dll 版本。它允许您在 C# 的另一个应用程序上单击控件、将字符串写入编辑框、进行组合框选择等。

Answer 5

使用SendMessage 原生 Win32 API。 DllImport 这个方法来自 User32.dll。您可以使用此 API 发送键盘和鼠标消息

Answer 6

我也尝试过这样做：为了使用鼠标，我使用了这个类

（需加using System.Runtime.InteropServices;）

public class MouseClick1    //public is important here**
    {
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);


        private const int MOUSEEVENTF_LEFTDOWN = 0x02;
        private const int MOUSEEVENTF_LEFTUP = 0x04;
        private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
        private const int MOUSEEVENTF_RIGHTUP = 0x10;


        public int CoordX { get; set; }    
        public int CoordY { get; set; }

                public void Click1()
        {

            Cursor.Position = new Point(CoordX, CoordY);

            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

        }

    }

在你的 form1 之后（假设名字是 form1）你可以

 public partial class form1 : Form
    {

 MouseClick1 button1 = new MouseClick1();
 MouseClick1 button2 = new MouseClick1();

[...]

    public void Simulate_button1and2_Click(object sender, EventArgs e)
    {

       button1.CoordX = 1652;   //random coordinates
       button1.CoordY = 225;
       button2.CoordX = 1650;
       button2.CoordY = 250;

       button1.Click1();
       button1.Click2();

} }

为了在指针上显示坐标，我使用了计时器和标签：

 private void timer1_Tick(object sender, EventArgs e)
        {
            Coord.Text = Cursor.Position.X.ToString() + " : " + Cursor.Position.Y.ToString();  //Premet d'avoir les coord en direct

        }

和我一起好好工作。
