复制代码 config文件:

- //MySql连接字符串
- "MySql": "Server=127.0.0.1;Database=db_test;User ID=root;Password=123456;SslMode=None;allowPublicKeyRetrieval=true;"//开发环境

复制代码 调用举例:
- //查询
- public static List<tb_equip> Get_EquipList()
- {
- SqlSugarHelper sugar = new SqlSugarHelper();
- var db = sugar.SqlClient();
- try
- {
- var gsList = db.Queryable<tb_equip>()
- .Where(a => a.IsUsing == true)//使用中
- .WhereIF(!string.IsNullOrWhiteSpace(PowerStation), a => a.PowerStation.Equals(PowerStation))//可选条件
- .ToList();
- return gsList;
- }
- catch (Exception ex)
- {
- Console.WriteLine("Get_TH70M_EquipList() " + ex.Message);//打印结果
- return null;
- }
- }
- //添加
- public static bool tb_tcp_log_add(Socket send, decimal wd_dec, decimal sd_dec, tb_equip equip, string packet, TcpType tcpType)
- {
- SqlSugarHelper sugar = new SqlSugarHelper();
- var db = sugar.SqlClient();
- tb_tcp_log log = new tb_tcp_log();
- log.TCP_IP_STR = send.RemoteEndPoint.ToString();//IP原文
- log.TCP_IP = Tools.SocketFormat(send.RemoteEndPoint.ToString());//IP格式化
- log.UUID = Guid.NewGuid().ToString();//主键(必须)
- log.Type = tcpType.ToString(); //类型
- int cc = db.Insertable(log).ExecuteCommand();//添加到数据库
- Console.WriteLine($"添加到数据库,成功添加{cc}条...");//打印结果
- if (cc > 0)
- {
- WriteLineAndLog("已添加");
- }
- return cc > 0;
- }
