c# - 将catch块中的2个语句合并为一个

Question

有人知道是否可以将下面的catch块中的代码编写为单个语句？我无法想出办法,如果有的话,我只是很好奇.

重要信息:必须保留堆栈跟踪.

    catch (Exception e)
    {
        if (e is MyCustomException)
        {
            // throw original exception
            throw;
        }

        // create custom exception
        MyCustomException e2 =
            new MyCustomException(
                "An error occurred performing the calculation.", e);
        throw e2;
    }

关于什么:

catch (MyCustomException)
{
   throw;
}
catch (Exception ex)
{
   throw new MyCustomException(ex);
}
