创建实例2中方法
1、构造函数
Type t = typeof(NewClassw);
Type[] pt = new Type[2];
pt[0] = typeof(string);
pt[1] = typeof(string);
//根据参数类型获取构造函数
ConstructorInfo ci = t.GetConstructor(pt);
//构造Object数组，作为构造函数的输入参数
object[] obj = new object[2]{“grayworm”,“hi.baidu.com/grayworm”};
//调用构造函数生成对象
object o = ci.Invoke(obj); /
/调用生成的对象的方法测试是否对象生成成功
//((NewClassw)o).show();
2、Activator.CreateInstance
Type t = typeof(NewClassw);
//构造函数的参数
object[] obj = new object[2] { “grayworm”, “hi.baidu.com/grayworm” };
//用Activator的CreateInstance静态方法，生成新对象
object o = Activator.CreateInstance(t,“grayworm”,“hi.baidu.com/grayworm”);
//((NewClassw)o).show();
