具体步骤如下：

1、 在程序入口处，即Program.cs添加如下代码：

DevExpress.UserSkins.OfficeSkins.Register();

DevExpress.UserSkins.BonusSkins.Register();

2、 所应用样式窗体需要继承自DevExpress.XtraEditors.XtraForm;

3、 添加defaultLookAndFeel1控件；

4、 在应用窗体调用如下代码：

 #region 初始化皮肤
        private void InitSkin()
        {
            BarSubItem bar = new BarSubItem();
            bar.Caption = "皮肤设置";
            bar.Name = "皮肤设置";
            //迭代出所有皮肤样式
            foreach (DevExpress.Skins.SkinContainer skin in DevExpress.Skins.SkinManager.Default.Skins)
            {
                BarButtonItem barBI = new BarButtonItem();
                barBI.Tag = skin.SkinName;
                barBI.Name = skin.SkinName;
                barBI.Caption = skin.SkinName;
                barBI.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(ItemClick);

                this.barManager1.Items.AddRange(new DevExpress.XtraBars.BarItem[] { barBI });
                bar.LinksPersistInfo.AddRange(new DevExpress.XtraBars.LinkPersistInfo[] { new DevExpress.XtraBars.LinkPersistInfo(barBI) });

            }
            this.barManager1.Items.AddRange(new DevExpress.XtraBars.BarItem[] { bar });
            this.barMenu.LinksPersistInfo.AddRange(new DevExpress.XtraBars.LinkPersistInfo[] { new DevExpress.XtraBars.LinkPersistInfo(bar) });
        }
        #region 皮肤单击事件
        private void ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            defaultLookAndFeel1.LookAndFeel.SetSkinStyle(e.Item.Tag.ToString());
            e.Item.Hint = e.Item.Tag.ToString();
        }
        #endregion
