C＃case statement issue

Question

WP7用アプリを作成していますが、この場合はステートメントエラーが出てきます。 3番目のケースに表示されます。 「ケース・エラーが発生しない」ことを示します。私はこのエラーを探知したし、私が正しく集中していない限り、私はすべてを正しく設定していると確信しています。 case 3:で

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)

Answer 1

 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. 

Answer 2

あなたは、内側switch外break文はありません。したがって、次のステートメントへの暗黙のフォールスルーがあります（次のステートメントがないにもかかわらず）。

Answer 3

第三のケースはbreak文をミス：

  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 
    }
