来一点反射和Emit，让ORM的使用极度简化
我们用一点反射和一点Emit，来完成这个过程: 反射得到构造函数和属性定义： //得到类型生成器 TypeBuilder typeBuilder (targetType); //定义构造函数 BuildConstructor(typeBuilder, newTypeParent, targetType.Name MethodAttributes.Final; //构造Get访问器 MethodBuilder getPropMethodBuilder = typeBuilder.DefineMethod getPropMethodBuilder); //构造Set访问器 MethodBuilder setPropMethodBuilder = typeBuilder.DefineMethod SetFieldNamesBuilder, propertyNames.ToArray()); //真正创建，并返回 Type resuleType=typeBuilder.CreateType
