1.安装SqlSugar我的环境是.net 10.
2.编写helper类
using SqlSugar; namespace xxx.Helper.DB { public static class SqlSugarHelper { private static SqlSugarScope _db; static SqlSugarHelper() { string mysqlConnectionStr = AppSettingsHelper.Configuration["DB:MySQLConnStr"] ?? ""; // 初始化数据库连接 _db = new SqlSugarScope(new ConnectionConfig() { ConnectionString = mysqlConnectionStr,// "server=localhost;port=3306;database=testdb;user=root;password=123456;", DbType = SqlSugar.DbType.MySql, IsAutoCloseConnection = true, // 自动关闭连接 InitKeyType = InitKeyType.Attribute, // 从特性读取主键和自增列信息 //ConfigureExternalServices = new ConfigureExternalServices() //{ // EntityService = (c, p) => // { // // 设置列的默认值 // if (p.IsPrimarykey == false && p.PropertyName == "Id") // { // p.IsIgnore = true; // 忽略非主键的Id列 // } // } //} }); //// 设置AOP事件 //_db.Aop.OnLogExecuting = (sql, pars) => //{ // Console.WriteLine($"SQL: {sql}"); // Console.WriteLine($"Parameters: {string.Join(", ", pars.Select(p => $"{p.ParameterName}:{p.Value}"))}"); //}; _db.Aop.OnError = (exp) => { Console.WriteLine($"SQL Error: {exp.Sql}"); Console.WriteLine($"Error Message: {exp.Message}"); }; } // 获取数据库实例 public static SqlSugarScope Db => _db; // 查询多个对象（使用 SQL） public static List<T> GetList<T>(string sql, object parameters = null) where T : class, new() { return _db.Ado.SqlQuery<T>(sql, parameters); } public static void ExcuteSqlString(string sql, object parameters = null) { _db.Ado.ExecuteCommand(sql, parameters); } } }
