问题描述
有没有办法在C＃中轻松实现以下pseduo代码：
Is there any way in C# to easily achieve the following pseduo-code:
try
{
...
}
catch ( ExceptionTypeA, ExceptionTypeB, ExceptionTypeC as ex)
{
... same code for all threw
}
或
try
{
...
}
catch ( ExceptionTypeA ex )
catch ( ExceptionTypeB ex )
catch ( ExceptionTypeC ex )
{
... same code for all exceptions of A, B or C
}
的所有例外的相同代码我想我是什么对于异常类型，m表示将会很好。
I guess what I'm saying would be great would be fall-through on exception types.
推荐答案
提到的语法问题（带有 ex ）是：什么属性/ membe rs应该 ex 有？不同的异常类型不一定兼容，除非有涉及的继承（在这种情况下，捕获您最关心的最少派生）。
The problem with the syntax as mentioned (with an ex) is: what properties/members should ex have? Different exception types are not necessarily compatible, unless there is inheritance involved (in which case, catch the least-derived that you care about).
唯一的当前选项是只需使用异常ex （或类似的）和检查（是 / as ）在处理程序内。
The only current option is to just use Exception ex (or similar) and check (is/as) inside the handler.
或;将共同代码重构成一个可以被三方使用的方法？
Or; refactor the common code into a method that can be used by all three?
