简单事务使用

  public static void ChangeType(string loupanid, int OpenPeriod)
        {
            string sqlStr = @"";
            SqlConnection con = new SqlConnection("");
            SqlCommand cmd = new SqlCommand(sqlStr, con);
            con.Open();
            SqlTransaction trans = con.BeginTransaction();
            try
            {
                cmd.ExecuteNonQuery();
                trans.Commit();
            }
            catch
            {
                trans.Rollback();
            }
            finally
            {
                con.Close();
                trans.Dispose();
                con.Dispose();
            }
        }
