        string connectionString = "your_connection_string";
        string query = "your_sql_query";

            using (SqlCommand command = new SqlCommand(query, connection))
            {
                // 执行查询
                SqlDataReader reader = command.ExecuteReader();

                // 在cmd.execute处停止查询
                command.Cancel();

                // 处理查询结果
                while (reader.Read())
                {
                    // 处理每一行数据
                }

                reader.Close();
            }
