在FormBorderStyle.None时调出任务栏右键

当FormBorderStyle = System.Windows.Forms.FormBorderStyle.None时,应用程序在任务栏中无法弹出右键;下面通过调用API调出右键菜单:

        [DllImport("user32.dll", EntryPoint = "GetWindowLong", CharSet = CharSet.Auto)]
        public static extern int GetWindowLong(HandleRef hWnd, int nIndex);
        [DllImport("user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto)]
        public static extern IntPtr SetWindowLong(HandleRef hWnd, int nIndex, int dwNewLong);
            int WS_SYSMENU = 0x00080000; // 系统菜单
            int WS_MINIMIZEBOX = 0x20000; // 最大最小化按钮
            int windowLong = GetWindowLong(new HandleRef(this, this.Handle), -16);
            SetWindowLong(new HandleRef(this, this.Handle), -16, windowLong | WS_MINIMIZEBOX | WS_SYSMENU);
