System.Exception与System.SystemException [英] System.Exception vs System.SystemException

问题描述

System.Exception与System.SystemException有什么区别

What is the difference between System.Exception vs System.SystemException

推荐答案

通常，SystemException保留供.NET运行时/框架使用，而不是您的应用程序代码.基本上，在创建自己的自定义Exception类时不要从SystemException派生.

A SystemException is usually reserved for the .NET runtime/framework to use, and not your application code. Basically, don't derive from SystemException when creating your own custom Exception class.

如果要创建自己的Exception类，则应该从Exception或ApplicationException派生它们.ApplicationException最初旨在用于非框架异常，但它已经被抛在了一边.我相信框架作者现在建议从基本Exception类派生自定义Exception.

If you are creating your own Exception classes, you should either derive them from Exception or ApplicationException. ApplicationException was originally intended to be used for non-framework exceptions, but it has sort of fallen to the wayside. I believe the framework authors now recommend to derive your custom Exceptions from the base Exception class.
