c# – System.dll中出现’System.Net.WebException’类型的第一

这是代码：

public static void FindFollowersForUser(TwitterUserModel twitterUser)
{
    try
    {
        var followers = service.ListFollowersOf(twitterUser.TwitterName,-1);
        if (followers == null) return;
        while (followers.NextCursor != null)
        {
            var foundFollowers = service.ListFollowersOf(twitterUser.TwitterName,(long)followers.NextCursor);
            if (foundFollowers == null) continue;

            Debug.WriteLine("Followers found for: " + twitterUser.TwitterName);
            foreach (var follower in foundFollowers)
            {
                twitterUser.Followers.Add(follower.ScreenName);
            }
        }
    }
    catch (WebException e)
    {
        throw e;
    }
}

我已经尝试在try / catch中包装代码,以捕获被触发的WebException错误并查看它的InnerException,但是尽管在Visual的输出窗口(View – > Output)中显示了错误消息,但永远不会输入catch工作室.

我怎么能看到这个突破bug的内在异常？这是我第一次看到调试器在触发异常时没有触发catch.
