Csharp 如何在 .Net 6 中处理 Win32 WndProc 消息

这是Program.cs文件的完整内容，在我了解了如何对User32进行子类化之后.WNDCLASS.项目使用.新console template that uses implicit using statements and no explicit class definition or Main method.的净6

• 加上PInvoke Win32 nuget package
• 允许在项目中使用usafe代码

代码如下:

using PInvoke;

unsafe
{
    User32.WndProc myWndProc = CustomWndProc;
    string className = "MyClassName";
    fixed (char* namePointer = className)
    {
        var window = new User32.WNDCLASS();
        window.lpszClassName = namePointer;
        window.lpfnWndProc = myWndProc;
        var ret = User32.RegisterClass(ref window);
        if (ret != 0)
        {
            // do some error handling here...
        }

        var windowHandle = User32.CreateWindowEx(
                                            User32.WindowStylesEx.WS_EX_APPWINDOW,
                                            className,
                                            "Window Title",
                                            User32.WindowStyles.WS_OVERLAPPEDWINDOW |
                                            User32.WindowStyles.WS_VISIBLE,
                                            100,
                                            100,
                                            800,
                                            800,
                                            IntPtr.Zero,
                                            IntPtr.Zero,
                                            IntPtr.Zero,
                                            IntPtr.Zero);
        User32.MSG msg;
        while (User32.GetMessage(&msg, windowHandle, User32.WindowMessage.WM_NULL, User32.WindowMessage.WM_NULL) > 0)   // synchonous call, will block the thread till a message is received
        {
            User32.TranslateMessage(&msg);
            User32.DispatchMessage(&msg);
        }
    }

    static IntPtr CustomWndProc(IntPtr hWnd, User32.WindowMessage msg, void* wParam, void* lParam)
    {
        return User32.DefWindowProc(hWnd, msg, (IntPtr)wParam, (IntPtr)lParam);
    }
}

delegate User32.WndProc WndProcDelegate(IntPtr hWnd, uint msg, IntPtr wParam, IntPtr lParam);

Edit:我使用PInvoke nuget包添加了WndProc消息的处理.
