c# winform 怎么给程序的按钮上也加上小盾牌图标

      作者：simadi

需要调用Win32 API了

【1】要调用API么，要先引用命名空间

using System.Runtime.InteropServices;

【2】然后调用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上拖个Button，拖大一点哦，小了图标看不清

 



【3】然后在Form1_Load里，用API把图标加到Button1上

        private void Form1_Load(object sender, EventArgs e)

        {

            EnableElevateIcon_BCM_SETSHIELD(button1);

        }

最后执行看下效果吧！





  恩？盾牌为啥有点不一样呢，上面那个图标是server08上的，win7上应该是下面这样：
