使用

 1  //代理生成器
 2  ProxyGenerator generator = new ProxyGenerator();
 3  //拦截器
 4  MyInterceptor interceptor = new MyInterceptor();
 5  //代理生成器使用拦截器生成代理对象
 6  IDBHelper dbhelper = generator.CreateClassProxy<MySqlDBHelper>(interceptor);
 7  Console.WriteLine("生成的类型时：{0}", dbhelper.GetType());
 8  int[] c = new int[3];
 9  c[0] = 1;
10  c[1] = 2;
11  c[2] = 3;
12  int c1 = 2;
13  dbhelper.show(2,3,c,ref c1);
14  dbhelper.show1();
