Cannot access SqlTransaction object to rollback in catch block

Question

I\'ve got a problem, and all articles or examples I found seem to not care about it.

I want to do some database actions in a transaction. What I want to do is very s

Answer 1

using (var Conn = new SqlConnection(_ConnectionString))
{
    SqlTransaction trans = null;
    try
    {
        Conn.Open();
        trans = Conn.BeginTransaction();

        using (SqlCommand Com = new SqlCommand(ComText, Conn, trans))
        {
            /* DB work */
        }
        trans.Commit();
    }
    catch (Exception Ex)
    {
        if (trans != null) trans.Rollback();
        return -1;
    }
}

or you could go even cleaner and easier and use this:

using (var Conn = new SqlConnection(_ConnectionString))
{
    try
    {
        Conn.Open();
        using (var ts = new System.Transactions.TransactionScope())
        {
            using (SqlCommand Com = new SqlCommand(ComText, Conn))
            {
                /* DB work */
            }
            ts.Complete();
        }
    }
    catch (Exception Ex)
    {     
        return -1;
    }
}
