C#中有没有不用如此麻烦的使用windows api 的方法呢

[DllImport("User32.dll", EntryPoint = "FindWindow")]
        public static extern int FindWindow(string lpClassName,string lpWindowName);
        [DllImport("user32.dll", EntryPoint = "FindWindowEx")]
        private static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
        [DllImport("User32.dll", EntryPoint = "SendMessage")]
        private static extern int SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, string lParam);
        [DllImport("user32.dll", EntryPoint = "EnumDesktopWindows", ExactSpelling = false, CharSet = CharSet.Auto, SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool EnumDesktopWindows(IntPtr hDesktop, EnumDesktopWindowsDelegate lpEnumCallbackFunction, IntPtr lParam);
        public delegate bool EnumDesktopWindowsDelegate(IntPtr hWnd, uint lParam);
