如何在 C# 中使用 RegisterHotKey()? [英] how to use RegisterHotKey() in C#?

问题描述

我正在尝试注册一个热键，我正在翻译 这个 C++代码转换成C#:

I'm trying to register a hot key, I'm translating this C++ code into C#:

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace ConsoleApplication1
{
    class Program
    {
        [DllImport("user32.dll")]
        public static extern
            bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, int vk);
        [DllImport("user32")]
        public static extern
            bool GetMessage(ref Message lpMsg, IntPtr handle, uint mMsgFilterInMain, uint mMsgFilterMax);

        public const int MOD_ALT = 0x0001;
        public const int MOD_CONTROL = 0x0002;
        public const int MOD_SHIFT = 0x004;
        public const int MOD_NOREPEAT = 0x400;
        public const int WM_HOTKEY = 0x312;
        public const int DSIX = 0x36;
        
        static void Main(string[] args)
        {
            if (!RegisterHotKey(IntPtr.Zero, 1, MOD_ALT | MOD_NOREPEAT, DSIX))
            {
                Console.WriteLine("failed key register!");
            }

            Message msg = new Message();

            while (!GetMessage(ref msg, IntPtr.Zero, 0, 0))
            {
                if (msg.message == WM_HOTKEY)
                {
                    Console.WriteLine("do work..");
                }
            }

            Console.ReadLine();
        }
    }

    public class Message
    {
        public int message { get; set; }
    }
}

但 RegisterHotKey() 永远不会返回 false.我不确定方法中传递的参数，IntPtr.Zero 应该为 null，并且消息类构造函数的第二个参数需要一个对象.非常感谢任何帮助！

but RegisterHotKey() never returns false. I'm not sure about the arguments passed in the method, IntPtr.Zero should be null, and message class constructor's second argument requires an object. any help is very appreciated!

这可能会有所帮助:

控制台应用程序中的热键

基本上，您必须创建一个隐藏"表单才能使其工作

Basically, you have to create a "hidden" form to make it work
