c# winform 怎麼給程序的按鈕上也加上小盾牌圖標

需要調用Win32 API了

要調用API麼，要先引用命名空間

using System.Runtime.InteropServices;

然後調用API

        [DllImport("user32.dll")]
        private static extern IntPtr SendMessage(HandleRef hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

        ///////////////////////////////////////////////////////////////////////
        /// <summary>
        ///     Enables the elevated shield icon on the given button control
        /// </summary>
        /// <param name="ThisButton">
        ///     Button control to enable the elevated shield icon on.
        /// </param>
        ///////////////////////////////////////////////////////////////////////
        private void EnableElevateIcon_BCM_SETSHIELD(Button ThisButton)
        {
            // Input validation, validate that ThisControl is not null
            if (ThisButton == null)
            {
                return;
            }

            // Define BCM_SETSHIELD locally, declared originally in Commctrl.h
            uint BCM_SETSHIELD = 0x0000160C;

            // Set button style to the system style
            ThisButton.FlatStyle = FlatStyle.System;

            // Send the BCM_SETSHIELD message to the button control
            SendMessage(new HandleRef(ThisButton, ThisButton.Handle), BCM_SETSHIELD, new IntPtr(0), new IntPtr(1));
        }

在Form上拖個Button，拖大一點哦，小了圖標看不清

然後在Form1_Load裡，用API把圖標加到Button1上

        private void Form1_Load(object sender, EventArgs e)
        {
            EnableElevateIcon_BCM_SETSHIELD(button1);
        }最後執行看下效果吧！
  恩？盾牌為啥有點不一樣呢，上面那個圖標是server08上的，win7上應該是下面這樣： 
有錯誤的地方歡迎指出。
