Console.WriteLine("AAAOnIncrement, on \n ");
e.Handled = true;
}
}
}private void OnIncrementOrDecrement(object sender, HotkeyEventArgs e)
{
switch (e.Name)
{
case "Increment":
Value++;
break;
case "Decrement":
Value--;
break;
}
e.Handled = true;
}该方法是全局快捷键, 注册后无论窗口焦点在不在都会触发, 关闭窗口后失效.

如果需要窗口快捷键, 那么利用重载系统函数的办法能够更好的操作:
protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { Console.WriteLine(keyData.ToString()); return base.ProcessCmdKey(ref msg, keyData); }然后自己在重载里各种配置就好
如下:
protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { Console.WriteLine(keyData.ToString()); if (keyData == Keys.Tab) { return false;//继续传递 } //return base.ProcessCmdKey(ref msg, keyData);//返回调用 return true;//阻止继续传递 }
