winform设置背景图闪屏问题解决

直接将以下代码复制粘贴到出现闪屏的窗体中即可:

       #region 解决添加背景图片时闪屏的问题
        protected override CreateParams CreateParams
        {
            get
            {

                CreateParams cp = base.CreateParams;

                cp.ExStyle |= 0x02000000;  // Turn on WS_EX_COMPOSITED

                if (this.IsXpOr2003 == true)
                {
                    cp.ExStyle |= 0x00080000;  // Turn on WS_EX_LAYERED
                    this.Opacity = 1;
                }

                return cp;

            }

        }  //防止闪烁

        private Boolean IsXpOr2003
        {
            get
            {
                OperatingSystem os = Environment.OSVersion;
                Version vs = os.Version;

                if (os.Platform == PlatformID.Win32NT)
                    if ((vs.Major == 5) && (vs.Minor != 0))
                        return true;
                    else
                        return false;
                else
                    return false;
            }
        }
        #endregion
