[通过反射，创建类的实例二][Link 1]

这次我们通过传递参数和定义接口的方式来创建实例

namespace Interface
    {
        public interface IObjcet
        {
            void Put();
            void Put(string plus);
        }
    }

using System;
    
    namespace NetStar.Biz
    {
        public class PlugPut : Interface.IObjcet
        {
            private string plugName = "";
    
            public string PlugName
            {
                get { return plugName; }
                set { plugName = value; }
            }
    
            public PlugPut() { }
    
            public PlugPut(string plusName)
            {
                this.PlugName = plusName;
            }
    
            public void Put()
            {
                Console.WriteLine("Default plug value is:" + plugName);
            }
    
            public void Put(string plus)
            {
                Console.WriteLine("Put plus value is:" + plus);
            }
        }
    }

static void Main(string[] args)
    {
        Console.WriteLine("");
    
        Test1();
    
        Console.ReadLine();
    }
    
    static void Test1()
    {    
        Type t = Type.GetType("NetStar.Biz.PlugPut,NetStar.Biz");
    
        //用Activator.CreateInstance创建默认的不带参数的构造函数
        IObjcet obj = (IObjcet)Activator.CreateInstance(t, null);
        obj.Put();
        obj.Put("plug 1");
    
        //用Activator.CreateInstance创建另一个带参数构造函数实例
        IObjcet obj2 = (IObjcet)Activator.CreateInstance(t, new string[] { "Hello world！" });
        obj2.Put();
        obj.Put("plug 2");
    }
