c#反射机制

例子：

using System;
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
  
namespace ITOO.Reflection.Student  
{  
    public class Student  
    {  
        public string Name { get; set; }  
  
        public int Age { get; set; }  
  
        // 默认构造函数  
        public Student()  
        {  
            this.Age = 24;  
            this.Name = "连江伟";  
        }  
        //带参数的构造函数  
        public Student(string name,int age)  
        {  
            this.Name = name;  
            this.Age = age;  
        }  
  
        public void Hello()  
        {  
            Console.WriteLine("我是"+Name +"，我今年"+Age +"岁了！");  
        }  
    }  
｝

利用反射操纵这个类 

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Reflection;  
  
namespace ITOO.Reflection.Client  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            //动态加载DLL，这个LoadFile最方便，参数就是dll的路径。  
            var asm = Assembly.LoadFile(@"C:\Users\ljw\Desktop\学习例子\ITOO.Reflection.Test\ITOO.Reflection.Student\bin\Debug\ITOO.Reflection.Student.dll");  
            //获取Student类的类型  
            var type = asm.GetType("ITOO.Reflection.Student.Student");  
            //创建该类的实例  
            var instance = asm.CreateInstance("ITOO.Reflection.Student.Student");  
            //为学生类的属性赋值  
            type.GetProperty("Name").SetValue(instance, "段天涯", null);  
            type.GetProperty("Age").SetValue(instance, 18, null);  
            //获取Student类的方法  
            var method = type.GetMethod("Hello");  
            //调用Student类的成员方法Hello  
            method.Invoke(instance, null);  
            Console.Read();  
        }  
    }  
}
