C#全局快捷键

[free_loop]

假如我想实现用Alt+D实现隐藏窗口，然后用Alt+H显示 请问怎么实现。

使用RegisterHotKey和UnregisterHotKey这两个WINAPI

// 定义常量和方法
private const int HIDE_ID = 0x1111;
private const int SHOW_ID = 0x1112;

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, uint vk);

// 窗体构造函数添加代码
const uint MOD_ALT = 0x0001;
RegisterHotKey(this.Handle, HIDE_ID, MOD_ALT, (uint)Keys.D);
RegisterHotKey(this.Handle, SHOW_ID, MOD_ALT, (uint)Keys.H);

// 重写窗体 WndProc 方法
protected override void WndProc(ref Message m)
{
    const int WM_HOTKEY = 0x0312;
    switch (m.Msg)
    {
        case WM_HOTKEY:
            {
                switch (m.WParam.ToInt32())
                {
                    case HIDE_ID:
                        this.Visible = false;
                        break;
                    case SHOW_ID:
                        this.Visible = true;
                        break;
                    default:
                        break;
                }
                break;
            }
        default:
            break;
    }
    base.WndProc(ref m);
}
