c# case语句问题
本文关键字：问题 语句 case | 更新日期: 2023-09-27 18:04:41
为WP7制作应用程序，但遇到了这个case语句错误。它出现在第三个案例中。给出了"不能通过大小写错误"。我已经在谷歌上搜索了这个错误，除非我没有集中注意力，否则我确信我已经正确设置了一切。
private void SortFeedData(int fs)
{
//only using cases 1,2,3 since 0 is for the news page which doesn't need sorting
switch (fs)
{
case 1:
//Sort feed data for "Scores" Page
switch (ButtonSourceLeague)

//clears all current feed data

case 3:
switch (ButtonSourceClub)
{
case "Manchester United":
App.Data.FeedList.Add("rss xml link here");
break;
default:
MessageBox.Show("Error");
break;
}
}
}
}
}
case 3:
switch (ButtonSourceClub)
{
case "Manchester United":
App.Data.FeedList.Add("rss xml link here");
break;
default:
MessageBox.Show("Error");
break;
}
break; //Here's what you're missing.
在case 3:中，在内部switch之外没有break语句。因此，有一个隐式的跳转到下一个语句(即使没有下一个语句)。
第三种情况遗漏了break语句:
break;
case 3:
switch (ButtonSourceClub)
{
case "Manchester United":
App.Data.FeedList.Add("rss xml link here");
break;
default:
MessageBox.Show("Error");
break;
}
break; // <---- was missing
}
