NET Framework class library. It is the backbone of partially trusted code and is not restricted to file access, but rather affects everything from network access to windowing and more. When you use it in your own component code, users will be able to execute code regardless of origin, and their systems will remain safe. This allows you to write code that is featureful, executes in native machine language, and is distributed across a LBN or even over the Internet. You can take advantage of this feature with only a minimal exposure to the underlying mechanics of code access security.

NET框架类库来施用他是半信托代码的根蒂根基而且不受限于文件拜候，可是对路程经过过程收集拜候窗户或其它的不论什么情况都有至关的影响当您在您本身的组件代码中施用它时，用户可以在不消留心来历的情况下执行代码（好比从1个英特网网站），她们的体系仿照还是是安全的这似的您可以开具富有特征的、路程经过过程本机执行的而且漫衍拜候局域网甚至是英特网的代码您可以哄骗这些特征在代码拜候安全的根蒂根基下最小限度的袒露您的信息
