inputsimulator

窗体输入模拟器提供一个基于 win32 SendInput  方法的 模拟键盘鼠标输入的.net 接口。windows 输入模拟器可用于 WPF、windows 窗体和控制台应用程序, 实现模拟任意按键。

使用Nuget添加引用

install-Package InputSimulator

示例

例子1：单一按键

public void PressTheSpacebar()
{
  InputSimulator.SimulateKeyPress(VirtualKeyCode.SPACE);
}

 例子2：按键按下和放开

public void ShoutHello()
{
  // Simulate each key stroke
  InputSimulator.SimulateKeyDown(VirtualKeyCode.SHIFT);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_H);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_E);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_L);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_L);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_O);
  InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_1);
  InputSimulator.SimulateKeyUp(VirtualKeyCode.SHIFT);

  // Alternatively you can simulate text entry to acheive the same end result
  InputSimulator.SimulateTextEntry("HELLO!");
}

例子3:修饰按键 比如CTRL-C

public void SimulateSomeModifiedKeystrokes()
{
  // CTRL-C (effectively a copy command in many situations)
  InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.VK_C);

  // You can simulate chords with multiple modifiers
  // For example CTRL-K-C whic is simulated as
  // CTRL-down, K, C, CTRL-up
  InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.CONTROL, new [] {VirtualKeyCode.VK_K, VirtualKeyCode.VK_C});

  // You can simulate complex chords with multiple modifiers and key presses
  // For example CTRL-ALT-SHIFT-ESC-K which is simulated as
  // CTRL-down, ALT-down, SHIFT-down, press ESC, press K, SHIFT-up, ALT-up, CTRL-up
  InputSimulator.SimulateModifiedKeyStroke(
    new[] { VirtualKeyCode.CONTROL, VirtualKeyCode.MENU, VirtualKeyCode.SHIFT },
    new[] { VirtualKeyCode.ESCAPE, VirtualKeyCode.VK_K });
}

例子4：模拟文字输入

public void SayHello()
{
  InputSimulator.SimulateTextEntry("Say hello!");
}

检测按键的不同状态

public void GetKeyStatus()
{
  // Determines if the shift key is currently down
  var isShiftKeyDown = InputSimulator.IsKeyDown(VirtualKeyCode.SHIFT);

  // Determines if the caps lock key is currently in effect (toggled on)
  var isCapsLockOn = InputSimulator.IsTogglingKeyInEffect(VirtualKeyCode.CAPITAL);
}
