下面给出向数据库中批量插入数据的DBUtil中的ExSqlList方法
  public static bool ExSqlList(List<string > sqlList,out string exceptions)
        {

            exceptions = "";

            bool isSuccess = true;

            using (SqlConnection conn = new SqlConnection(sqlconn))
            {
                conn.Open();

                SqlCommand cmd = new SqlCommand();

                SqlTransaction trans = conn.BeginTransaction();

                cmd.Connection = conn;

                cmd.Transaction = trans;

                try
                {
                    foreach (string sql in sqlList)
                    {
                        cmd.CommandText = sql;

                        cmd.ExecuteNonQuery();
                    }

                    trans.Commit();
                }
                catch (Exception ex)
                {
                    isSuccess = false;
                    trans.Rollback();
                    exceptions = ex.Message.ToString();
                    throw new ApplicationException(exceptions);
                }
                return isSuccess;
            }
        }
