集合循環時刪除元素

 

foreach(KeyValuePair<string,Array> a in name2Array)
{
             for
             {
                 for
                 {
                 }
             }
             foreach()
             {
                 if()
                 {
                     name2Array.Remove(fullFileName);//刪除不符合條件一對鍵值;
                     break;
                    
                    
                 }
             }
}

因爲刪除集合再循環出錯

解決：
1、把foreach換成for就沒有問題

2、foreach外面加while  跳到froeach外面在進入foreach
