返回最内层的InnerException

Question

递归很简单：        string GetInnerException(Exception ex)
        {
            if (ex.InnerException != null)
            {
                return GetInnerException(ex.InnerException);
            }
            return ex.Message;        }

Answer 1

循环就可以。       var str = ex.Message;
       while (ex.InnerException != null)
       {
           ex = ex.InnerException;
           str += ex.ToString();   // ex.Message;
       }
