实例二

 步骤1:新建一个类库test1,在类库下有一个类ReflectTest.cs,此类中的代码如下:

using System;
using System.Collections.Generic;
using System.Text;

namespace test1
{
    public class ReflectTest
 {
  public ReflectTest()
  {}

  public string WriteString(string s)
  {
     return "欢迎您，" + s;
  }

  public static string WriteName(string s)
  {
     return "欢迎您光临，" + s;
  }

 public string WriteNoPara()
  {
      return "您使用的是无参数方法";
  }
 }
    public class ReflectTest_22
    { }
}

步骤2:

 建立一个类test_1.cs,代码如下:

using System;
using System.Text;
using System.Reflection;
public class test1
{
 public static void Main()
 {
   System.Reflection.Assembly ass;
   Type type ;
   object obj;
   try
    {
        //ass = Assembly.LoadFile(@"D:C#学习Chapter11WhatsNewAttributes est1objDebug est1.dll");
        //ass = Assembly.LoadFrom(@"D:C#学习Chapter11WhatsNewAttributes est1objDebug est1.dll");
        ass = Assembly.Load("test1");
        Type[] test_type1 = ass.GetTypes();
        foreach (Type t1 in test_type1)
        {
            Console.WriteLine(t1.Name);           
        }
        type = ass.GetType("test1.ReflectTest");//必须使用名称空间+类名称

        foreach (MemberInfo MI in type.GetMembers())
        {
            Console.WriteLine(MI.MemberType + "  " + MI.Name);           
        }

        Console.WriteLine("*******");

        MethodInfo method_1 = type.GetMethod("WriteString");//方法的名称
        obj = ass.CreateInstance("test1.ReflectTest");//必须使用名称空间+类名称

        string s = (string)method_1.Invoke(obj, new string[] {"jianglijun" }); //实例方法的调用
      
        Console.WriteLine(s);
        MethodInfo method_2 = type.GetMethod("WriteName");//方法的名称
        s = (string)method_2.Invoke(null,new string[]{"jianglijun"}); //静态方法的调用
        Console.Write(s);

        MethodInfo method_3 = type.GetMethod("WriteNoPara");//无参数的实例方法
        s = (string)method_3.Invoke(obj,null);
        Console.WriteLine(s);
        //method = null;
   }
   catch(Exception ex)
   {
        Console.WriteLine("出现错误!");
        Console.WriteLine(ex);
   }
   finally
   {
        ass = null;
        type = null;
        obj = null;
   }
 }
}

运行结果如下:
