相关疑难解决方法(0)

我有几个代码方法,如下所示:

using (var connection = this.connectionFactory.GetConnection())
{
    connection.Open();
    using (var transaction = connection.BeginTransaction())
    {
        using (var command = connection.CreateCommand())
        {
            command.Transaction = transaction;
            command.CommandText = "foo";
            command.ExecuteNonQuery();
            transaction.Commit();
        }
    }
}

我现在需要在外部事务中一起调用这些方法中的几个,所以我这样做了:

using (var transactionScope = new TransactionScope(TransactionScopeOption.RequiresNew))
{
    method1();
    method2();
    method3();
}

但它的做法是:

The operation is not valid for the state of the transaction.
