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，然后让实例方法创建一个TransactionScope吗？

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.

对

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

问题是您需要在创建 TransactionScope 之后创建与数据库的连接还是可以在之前完成？

Answer 1

如果您希望 SqlConnection 在事务下，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();
}
