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()); } }}
