使用TransactionScope時設置數據庫連接

Question

數據庫連接是否必須在TransactionScope內設置？

或者我可以在ctor中設置它，然後通過實例方法創建一個TransactionScope？

編輯：例如

Public Sub New() 
    Dim conn = new SqlConnection(...connection string) 
Public Sub SomeClassMethod() 
    using ts as new TransactionScope 
     //conn has already been initialized 
     //so, here you can set commands, ExecuteDataSet, etc. 

VS

Public Sub New() 
    //nothing here 
Public Sub SomeClassMethod()  
    using ts as new TransactionScope 
     conn = new SqlConnection(...connection string) 
     set commands, ExecuteDataSet, etc. 

的問題是你需要你創建一個TransactionScope後創建到數據庫的連接還是可以做之前？

Answer 1

如果您希望SqlConnection處於事務中，則需要在TransactionScope下創建它。

using(TransactionScope scope = new TransactionScope()) 
{ 
    SqlConnection x = new SqlConnestion("...."); 
    x.Open(); 
    ....your code... SQlCommands etc.... 
    x.Close(); 
    scope.Complete(); 
}
