在Teddy的 DynamicMethodProxyFactory组件中，提供了一种调用非公有方法的机制。本质上，通过这个组件是可以实现任意的公有和非公有属性的读写操作（属性本质上可以通过它的get/set方法以方法的形式访问）。而且性能会比反射提高3 - 4数量级。但是如果我们希望访问某些非公有字段时，那我们还是无法使用DynamicMethodProxyFactory组件，还是需要使用反射。
这时，NonPublicPropertyProxy就派上用场了。这个组件是我根据NBear.Mapping中对属性的读写原理抽取出来的。由于它仍然是基于IL和CodeGenerator，因此在性能仍然具备DynamicMethodProxyFactory的特点。
该组件实现的功能，通过代理非常简单的支持对任意实例属性(Property)/字段(Field)的读写，支持任意静态字段的读写。但不支持静态属性的读写（对静态属性的读写还得通过DynamicMethodProxyFactory）。
由于该组件会动态组织IL代理函数，因此在首次获取代理方法时，会需要一些性能损失（DynamicMethodProxyFactory也是如此）。因此如果只需一次读写非公有属性/字段时，还是尽可能选择其它方式，比如反射。
使用演示：
code 1 设置私有字段值
1 User user =
new User(); 2 NonPropertySetterDelegate nameSetter = NonPublicPropertyProxyFactory.GetPropertySetter(typeof(User), "name"); 3 NonPropertySetterDelegate idSetter = NonPublicPropertyProxyFactory.GetPropertySetter(typeof(User), "id"); 4 NonPropertySetterDelegate statusSetter = NonPublicPropertyProxyFactory.GetPropertySetter(typeof(User), "status"); 5 NonPropertySetterDelegate childrenSetter = NonPublicPropertyProxyFactory.GetPropertySetter(typeof(User), "Children"); 6 NonPropertySetterDelegate staticFieldSetter = NonPublicPropertyProxyFactory.GetPropertySetter(typeof(User), "staticValue"); 7
8
string name =
"abu"; 9 nameSetter(user, name);10
11
int i =
995006;12 idSetter(user, i);13
14 statusSetter(user, UserStatus.Admin);15
16 List<string> children =
new List<string>();17 childrenSetter(user, children);18
19 staticFieldSetter(null, 100);20
CODE 2 读取私有字段值
User user =
new User(995006, "abu", UserStatus.Admin);user.Children =
new List<string>();NonPropertyGetterDelegate nameGetter = NonPublicPropertyProxyFactory.GetPropertyGetter(typeof(User), "name");NonPropertyGetterDelegate idGetter = NonPublicPropertyProxyFactory.GetPropertyGetter(typeof(User), "id");NonPropertyGetterDelegate statusGetter = NonPublicPropertyProxyFactory.GetPropertyGetter(typeof(User), "status");NonPropertyGetterDelegate childrenGetter = NonPublicPropertyProxyFactory.GetPropertyGetter(typeof(User), "Children");NonPropertyGetterDelegate staticFieldGetter = NonPublicPropertyProxyFactory.GetPropertyGetter(typeof(User), "staticValue");int id = (int)idGetter(user);string name = nameGetter(user).ToString();UserStatus status = (UserStatus)statusGetter(user);List<string> children = (List<string>)childrenGetter(user);int staticFieldValue = (int)staticFieldGetter(null);
