发送鼠标和键盘事件

我正在开发一个必须将一些键或鼠标事件发送到活动窗口的应用程序。

我正在使用这个类： 鼠标

using System.Runtime.InteropServices; using System.Windows.Forms; namespace Mouse { public static class VirtualMouse { // import the necessary API function so .NET can // marshall parameters appropriately [DllImport("user32.dll")] static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo); // constants for the mouse_input() API function private const int MOUSEEVENTF_MOVE = 0x0001; private const int MOUSEEVENTF_LEFTDOWN = 0x0002; private const int MOUSEEVENTF_LEFTUP = 0x0004; private const int MOUSEEVENTF_RIGHTDOWN = 0x0008; private const int MOUSEEVENTF_RIGHTUP = 0x0010; private const int MOUSEEVENTF_MIDDLEDOWN = 0x0020; private const int MOUSEEVENTF_MIDDLEUP = 0x0040; private const int MOUSEEVENTF_ABSOLUTE = 0x8000; // simulates movement of the mouse. parameters specify changes // in relative position. positive values indicate movement // right or down public static void Move(int xDelta, int yDelta) { mouse_event(MOUSEEVENTF_MOVE, xDelta, yDelta, 0, 0); } // simulates movement of the mouse. parameters specify an // absolute location, with the top left corner being the // origin public static void MoveTo(int x, int y) { mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, x, y, 0, 0); } // simulates a click-and-release action of the left mouse // button at its current position public static void LeftClick() { mouse_event(MOUSEEVENTF_LEFTDOWN, Control.MousePosition.X, Control.MousePosition.Y, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, Control.MousePosition.X, Control.MousePosition.Y, 0, 0); } public static void RightClick() { mouse_event(MOUSEEVENTF_RIGHTDOWN, Control.MousePosition.X, Control.MousePosition.Y, 0, 0); mouse_event(MOUSEEVENTF_RIGHTUP, Control.MousePosition.X, Control.MousePosition.Y, 0, 0); } } } 

键盘

 using System.Runtime.InteropServices; using System.Windows.Forms; namespace Mouse { public static class VirtualKeyboard { [DllImport("user32.dll")] static extern uint keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo); public static void KeyDown(System.Windows.Forms.Keys key) { keybd_event((byte)key, 0, 0, 0); } public static void KeyUp(System.Windows.Forms.Keys key) { keybd_event((byte)key, 0, 0x7F, 0); } } } 

这是我的测试代码：

  private void button1_Click(object sender, EventArgs e) { Thread.Sleep(2000); VirtualMouse.Move(100, 100); VirtualMouse.RightClick(); VirtualKeyboard.KeyDown(System.Windows.Forms.Keys.A); VirtualKeyboard.KeyUp(System.Windows.Forms.Keys.A); } 

鼠标移动，但不发送点击。 任何的想法？ 如何让按键继续按下一段时间？ 我尝试在KeyDown和KeyUp之间使用thread.sleep并且它不起作用。

CodePlex上有一个开源项目（微软的开源网站）

Windows输入模拟器（C＃SendInput Wrapper – 模拟键盘和鼠标）

http://inputsimulator.codeplex.com/

它有例子，真的很简单。

你的定义应该是Uint32 ：

 private const UInt32 MOUSEEVENTF_LEFTDOWN = 0x02; private const UInt32 MOUSEEVENTF_ABSOLUTE = 0x8000; private const UInt32 MOUSEEVENTF_LEFTUP = 0x04; private const UInt32 MOUSEEVENTF_RIGHTDOWN = 0x08; private const UInt32 MOUSEEVENTF_RIGHTUP = 0x10;
