我们正在尝试使用下面的代码.NET 3.5和SQL Server 2005进行间接嵌套事务.

MSDN说,当使用TransactionScope时,只要应用程序在事务中打开第二个连接(甚至是同一个数据库),事务就会升级.

void RootMethod()
{
   using(TransactionScope scope = new TransactionScope())

     string insertString = @"
             insert into Categories
             (CategoryName, Description)
             values ('Laptop1', 'Model001')";
         conn1.Open();
         SqlCommand cmd = new SqlCommand(insertString, conn1);
         cmd.ExecuteNonQuery();
        }
      scope.Complete();
    }
 }

 void SecondMethod()
 {
    using(TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
   {
       using (SqlConnection conn2 …
