使用DevExpress改变WinForm皮肤(VS)

基于步入DevExpress的使用（VS），进一步使用DevExpress改变WinForm皮肤,适合初学者。

提示：

1、对于DevExpress菜单中的RepositoryItemComboBox没有EditValue属性，无法直接获取选择的值，但可以在其事件中将其转化为ComboBoxEdit控件来获取。如下：

private void repositoryItemComboBox1_SelectedValueChanged(object sender, EventArgs e)
{ 
     ComboBoxEdit riComboBox = sender as ComboBoxEdit;
     string skinName = riComboBox.EditValue.ToString();
} 

2、在设计界面代码如：BaseFormDesigner.cs中，手动给指定控件(RepositoryItemComboBox)添加事件,代码如下：

 this.repositoryItemComboBox1.SelectedValueChanged += new System.EventHandler(this.repositoryItemComboBox1_SelectedValueChanged);

　　在对应的BaseForm.cs中实现其具体功能，代码如下：

        /// <summary>
        /// 手动添加的 Combobox菜单项值改变时，触发的事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void repositoryItemComboBox1_SelectedValueChanged(object sender, EventArgs e)
        {
            ComboBoxEdit repositoryItemComboBox = sender as ComboBoxEdit;
            this.defaultLookAndFeel1.LookAndFeel.SkinName = repositoryItemComboBox.EditValue.ToString();     
        }

代码间关系：Program类主要注册要使用的皮肤及运行那个界面；CommonFunctions类主要实现共用的函数；BaseForm类继承自DevExpress.XtraEditors.XtraForm，主要实现一些基础共用的操作；SkinSubject类主要积累那些类共用BaseForm类的通用操作或共性（单例、简单观察者来实现）；AppFormA、AppFormB类都继承自BaseForm类，共用BaseForm类特性。

具体实例代码（不含界面设计代码）如下：

　

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;


namespace TestExpressSkins
{
    static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            DevExpress.UserSkins.BonusSkins.Register();
            DevExpress.UserSkins.OfficeSkins.Register();
            DevExpress.Skins.SkinManager.EnableFormSkins();
            
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new BaseForm());
            //Application.Run(new AppFormA());
            Application.Run( AppFormA.Singlon());
        }
    }
}
