若要验证您的程序码的变更签入之前，您可以使用私用的组建(也称为“好友组建”)。

You can use a private build (also known as a "buddy build") to validate changes to your code before you check it in.

也就是说，只要程序码完全受到信任，就可以使用反映来存取和叫用私用建构函式、方法、栏位和属性。

That is, private constructors, methods, fields, and properties can be accessed and invoked using Reflection whenever the code is fully trusted.

无法从一般编译程序码存取的私用、受保护或内部的方法，可利用反映从部份信任程序码存取。

A private, protected, or internal method that would not be accessible from normal compiled code is accessed from partially trusted code by using reflection.
