如何抛出一个从Exception继承的异常？ [英] How to throw a exception that doesnt inherit from Exception?

问题描述

我想在下面的代码的空catch块中测试一些异常处理逻辑。

I would like to test some exception handling logic in the empty catch block of the below code.

try
{
    //Do Some stuff that throws a exception 
    //This is the code i need
}
catch (Exception)
{
    //Handle things that inherits from Exception
}
catch
{
    //Handle things that dont inherits from Exception
    //Want to test this code
}

推荐答案

从CLR 2.0开始，这不是一个场景你需要担心。现在，CLR将自动将所有不会从System.Exception派生的异常包装为一个新的Exception类型 RuntimeWrappedException （文档）。

Starting with CLR 2.0 this is not a scenario that you need to worry about. The CLR will now automatically wrap all exceptions which do not derive from System.Exception with a new Exception of type RuntimeWrappedException (Documentation).

此包装可以通过启用应用程序兼容性级别禁用，但肯定不是正常或常见的情况

This wrapping can be disabled by enabling a level of application compatibility but it is certainly not the normal or common case
