歡迎堆棧溢出。當您提出問題時，請花費更多的精力來提供*簡短*但完整的程序，格式正確。它對您的問題有多大用處以及其他人閱讀並回答您的問題有多容易。 foreach循環 – 2014-12-08 06:59:06

緊密結合是...進出口新的堆棧溢出和編程.....以後我會提供短期和完整程序... – 2014-12-08 07:01:49

你不得不關閉foreach循環外的連接。

感謝üSOOOO多.....它的工作.. – 2014-12-08 07:05:54

你要在外面foreach loop或

增收連接下面的代碼行：

try 
{ 
    if(Dist.State != ConnectionState.Open) 
     Dist.Open(); 

    cmd1.ExecuteNonQuery(); 
}

ExecuteNonQuery需要一個開放和可用的連接。試圖噸運行它拋出一個例外是當前連接狀態下關閉該程序.. <br> 這裏的IAM使用兩個條件，並在單個連接2個指令..also我有一個疑問，這是當連接的當前狀態被關閉
