Silverlight 中的反射限制 [英] Reflection restrictions in Silverlight

问题描述

哪里描述了 Silverlight 类型的众所周知的反射限制?

Where described well-known reflection restrictions for Silverlight types?

例如:如果我尝试使用 PropertyInfo.SetValue 方法设置受保护或私有属性值，我会收到异常 MethodAccessException.

For example: if I try to set protected or private property value with PropertyInfo.SetValue method I get an exception MethodAccessException.

为什么会有这些限制?

推荐答案

出于安全目的，Silverlight 中的反射仅限于编译时可用的内容.大多数情况下，这意味着您只能访问公共成员.

For security purposes, reflection in Silverlight is limited to what is available at compile time. Mostly this means you can only access public members.

以下是 MS 对此的说明:http://msdn.microsoft.com/en-us/library/stfy7tfc(VS.95).aspx

Here's what MS says about it: http://msdn.microsoft.com/en-us/library/stfy7tfc(VS.95).aspx

这样做的原因是 Silverlight 内部结构大多是私有的或主要 Silverlight 程序集内部的.如果我可以在不检查任何参数的情况下调用这些私有函数，我也许可以编写一个 Silverlight 应用程序来读取您的私有文件或类似的东西.

The reason for this is that the Silverlight internals are mostly private or internal to the main Silverlight assembly. If I could call those private functions without any parameter checking, I might be able to write a Silverlight app that reads your private files or something like that.
