如果不这样做，则公开可见的安全关键类型和成员将被视为是安全可靠关键的，并且可以由程序集外部的部分信任的代码调用。

If you do not, publicly visible security-critical types and members are treated as security-safe-critical and can be called by partially trusted code outside the assembly.

使用1级透明度时，您会使用一种安全模型，该模型将代码分成三类方法：安全透明的方法、安全可靠关键的方法和安全关键的方法。

When you use Level 1 transparency, you are using a security model that separates code into security-transparent, security-safe-critical, and security-critical methods.

youdao

获取一个值，该值指示当前动态方法在当前信任级别上是否是安全可靠关键的；即它是否可以执行关键操作并可以由透明代码访问。

For example, if you associate a dynamic method with a type that is in mscorlib. dll, which has level 2 mixed transparency, the dynamic method is transparent and cannot execute critical code.
