使用TransactionScope时设置数据库连接

Question

数据库连接是否必须在TransactionScope内设置？

或者我可以在ctor中设置它，然后通过实例方法创建一个TransactionScope？

编辑：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. 

的问题是你需要你创建一个TransactionScope后创建到数据库的连接还是可以做之前？

Answer 1

如果您希望SqlConnection处于事务中，则需要在TransactionScope下创建它。

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