C#開發分享：如何改變系統鼠標樣式

開發過程中發現需要用到改變鼠標樣式（就是光標的樣子），但是在網上找了很多資料，都是介紹在程序中使用，我需要的效果時在系統級使用。現在找到了，分享給大家。

 

        [DllImport("user32")]
        private static extern IntPtr LoadCursorFromFile(string fileName);

        [DllImport("User32.DLL")]
        public static extern bool SetSystemCursor(IntPtr hcur, uint id);
        public const uint OCR_NORMAL = 32512;

        [DllImport("User32.DLL")]
        public static extern bool SystemParametersInfo(uint uiAction, uint uiParam,IntPtr pvParam, uint fWinIni);

        public const uint SPI_SETCURSORS = 87;
        public const uint SPIF_SENDWININICHANGE = 2;

        private void button_Click(object sender, RoutedEventArgs e)
        {
            //設置
            IntPtr iP = LoadCursorFromFile(@"D:\My Files\圖片\cursor.cur");
            SetSystemCursor(iP, OCR_NORMAL);
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            //恢復
            SystemParametersInfo(SPI_SETCURSORS, 0, IntPtr.Zero, SPIF_SENDWININICHANGE);
        }
