最近在学习 DevExpress 这个控件，将窗体换肤的一些心得记录下来，分享给大家：

1.添加引用：

2.在ribbonPageGroup下新建个ribbonGalleryBarItem，并添加GalleryItemClick 事件：ribbonGalleryBarItem1_GalleryItemClick：

3.在应用程序的主入口里添加：

static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            DevExpress.UserSkins.BonusSkins.Register();
            DevExpress.Skins.SkinManager.EnableFormSkins();
            DevExpress.Skins.SkinManager.EnableMdiFormSkins();

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault( false );
            Application.Run( new Form1());
        }
    }

4.在窗体代码里添加命名空间using System.Xml;在事件ribbonGalleryBarItem1_Click里添加代码：

private void ribbonGalleryBarItem1_GalleryItemClick(object sender, DevExpress.XtraBars.Ribbon.GalleryItemClickEventArgs e)
        {
            string caption = string.Empty;
            if (ribbonGalleryBarItem1.Gallery ==  null )  return ;
            //caption = ribbonGalleryBarItem1.Gallery.GetCheckedItems()[0].Caption;
            //上面那句会获取显示的名字，因为我已汉化，所以有中文，不能匹配UserLookAndFeel.Default.SetSkinStyle中的皮肤名称
            //无法达到关闭后再加载关闭前的皮肤，如已汉化，参考下面这句：
            caption = ribbonGalleryBarItem1.Gallery.GetCheckedItems()[ 0 ].Tag.ToString(); //获取真实的名称，没有汉化的
            caption = caption.Replace( "主题：" ,  "" );
            XmlDocument doc =  new XmlDocument();
            doc.Load( "SkinInfo.xml" );
            XmlNodeList nodelist = doc.SelectSingleNode( "SetSkin" ).ChildNodes;
            foreach (XmlNode node  in nodelist)
            {
                XmlElement xe = (XmlElement)node; //将子节点类型转换为XmlElement类型
                if (xe.Name ==  "Skinstring" )
                {
                    xe.InnerText = caption;
                }
            }
            doc.Save( "SkinInfo.xml" );
        }

5.添加命名空间using DevExpress.XtraBars.Helpers和using DevExpress.LookAndFeel;在Load下添加代码：

public string defaultSkinName; //皮肤
        private void useSkin_Load(object sender, EventArgs e)
        {
            SkinHelper.InitSkinGallery(ribbonGalleryBarItem1);
            CheckFile(); //检查文件
            GetXmlSkin(); //获取xml主题
            UserLookAndFeel.Default.SetSkinStyle(defaultSkinName); //设置主题样式
            ribbonGalleryBarItem1.Caption =  "主题：" + defaultSkinName;
        }

        #region 检查XML文件是否存在
        public void CheckFile()
        {
            try
            {
                if (System.IO.File.Exists( "SkinInfo.xml" ) ==  false )
                {
                    //XtraMessageBox.Show("不存在XML");
                    CreateXml();
                }
            }
            catch (Exception ex)
            {
                XtraMessageBox.Show(ex.ToString(),  "Error" , MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }

        #region 创建XML文件

        public void CreateXml()
        {
            XmlDocument doc =  new XmlDocument();
            //建立xml定义声明
            XmlDeclaration dec = doc.CreateXmlDeclaration( "1.0" ,  "utf-8" ,  null );
            doc.AppendChild(dec);

            //创建根节点
            XmlElement root = doc.CreateElement( "SetSkin" );
            XmlElement rootone = doc.CreateElement( "Skinstring" ); //皮肤


            //将one，two，插入到root节点下
            doc.AppendChild(root);
            root.AppendChild(rootone);
            doc.Save( "SkinInfo.xml" );
        }

        #endregion

        #region 读取Xml节点内容

        public void GetXmlSkin()
        {
            try
            {
                XmlDocument mydoc =  new XmlDocument();
                mydoc.Load( "SkinInfo.xml" );
                XmlNode ressNode = mydoc.SelectSingleNode( "SetSkin" );
                defaultSkinName = ressNode.SelectSingleNode( "Skinstring" ).InnerText;

            }
            catch (Exception ex)
            {
                XtraMessageBox.Show(ex.ToString(),  "Error" , MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }

        #endregion
        #endregion
