反射的帮助类

在做项目时，常常需要配置一些属性的，这就需要用到反射机制，下面是项目中常用到一些基本的放射方法：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; using System.Collections;namespace SKY.DEFINITION {/// <summary>/// 该类是用来实现反射的/// 范小军/// </summary>public class ReflectionAboutClass{/// <summary>/// 构造函数/// 传递一个对象进来/// </summary>/// <param name="obj"></param>public ReflectionAboutClass(){this.Ltype = new List<string>();this.Ltype2 = new List<string>();this.LValue = new List<string>();this.LClass = new List<string>();this.LAttribute = new List<string>();this.LAttribute2 = new List<string>();this.LMethodName = new List<string>();this.LDefaultValue = new List<string>();}#region 变量/// <summary>/// 用来保存对象中所有的属性/// </summary>public List<string> Ltype { get;
