我如何重置 Transactionscope 并在之后提交？

Question

我怎样才能做到这一点？这是可能的还是我应该声明另一个事务范围？

    using (TransactionScope scope = new TransactionScope())
        {
            using (SqlConnection connection1 = new SqlConnection(connectString1))
            {
                connection1.Open();

                SqlCommand command1 = new SqlCommand(NomProcedure, connection1);
                command1.CommandType = CommandType.StoredProcedure;
                command1.ExecuteNonQuery();

                //Rollback transaction Here 

                SqlCommand command2 = new SqlCommand("dbo.AddHistory", connection1);
                command2.CommandType = CommandType.StoredProcedure;
                command2.ExecuteNonQuery();

            }

            scope.Complete();
        }

我只想提交第二个命令

从您开始交易的那一刻起，对数据的任何更改都不会得到确认，直到您完成交易。

如果你想回滚，那么就不要调用Complete():

using (TransactionScope scope = new TransactionScope())
{
    ...
    // do not call this to rollback what you did before
    scope.Complete();
}

这可以通过在 try/catch 中有事务时抛出异常来完成（如 msdn 建议）或通过有条件地调用 Complete（if）。

如果你想在回滚事务中执行命令，那么它应该是这样的：

using (SqlConnection connection1 = new SqlConnection(connectString1))
{
    connection1.Open();
    using (TransactionScope scope = new TransactionScope())
    {
        ... // some commands

        // if you need to rollback and execute other command
        if(blabla)
        {
            scope.Dispose(); // without this further command is also rolled back
            ... // command
        }
        else
            scope.Complete(); // everything is fine, confirm transaction
    }
}
