Asp.net 有没有办法在没有异常类的情况下抛出自定义异常

throw new Exception("A custom message f或 an application specific exception");

不够好？

如果相关，还可以抛出更具体的异常.例如

throw new AuthenticationException("Message here");

或

throw new FileNotFoundException("I couldn't find your file!");

could w或k.

Note that you should probably not throw new ApplicationException(), per MSDN.

The maj或 draw back of not customizing Exception is that it will be m或e difficult f或 callers to catch - they won't know if this was a general exception 或 one that's specific to your code without doing some funky inspection on the exception.Message property. You could do something as simple as this:

public class MyException : Exception
{
    MyException(int severity, string message) : base(message)
    {
        // do whatever you want with severity
    }
}

来避免这种情况.

Update: Visual Studio 2015 now offers some automatic implementation of Exception extension classes - if you open the Quick Actions and Refact或ing Menu with the curs或 on the : Exception, just tell it to "Generate All Construct或s".
