.NetCore中使用SqlSugar

1.环境

2.依赖注入SqlSugar

    /// <summary>
    /// SqlSugar 依赖注入
    /// </summary>
    public static class SqlSugarInit
    {

        public static void AddSqlsugarSetup(this IServiceCollection services, string conn)
        {
            if (services == null) throw new ArgumentNullException(nameof(services));



            string sqlConn = conn;
            services.AddScoped<ISqlSugarClient>(o =>
            {
                var client = new SqlSugarClient(new ConnectionConfig()
                {
                    ConnectionString = sqlConn,//必填, 数据库连接字符串
                    DbType = (DbType)DbType.SqlServer,//必填, 数据库类型
                    IsAutoCloseConnection = false,//默认false, 是否自动关闭数据库连接, 设置为true无需使用using或者Close操作
                    InitKeyType = InitKeyType.Attribute //默认SystemTable, 字段信息读取, 如：该属性是不是主键，标识列等等信息
                });
                //用来打印Sql方便你调式    
                client.Aop.OnLogExecuting = (sql, pars) =>
                {
                    Console.WriteLine(sql + "\r\n" +
                    client.Utilities.SerializeObject(pars.ToDictionary(it => it.ParameterName, it => it.Value)));
                    Console.WriteLine();
                };

                return client;
            });
        }
    }

在Startup类中进行注入：

 public void ConfigureServices(IServiceCollection services)
        {
            #region SqlSugarCore
            //依赖注入SqlSugar            
            services.AddSqlsugarSetup(Configuration.GetSection("ConnectionStrings").GetSection("MSSQLConnection").Value);
            #endregion
            services.AddControllers();
        }

3.基类中使用
