前言

我之前介绍过EFCore 怎么使用Nuget快速创建数据库，我之后发现SqlSugar更快。这里简单再说一下SqlSugar如何使用
.NET Core 数据库DB First自动生成，Sqlite,sql server,Mysql

SqlSugar使用

SqlSugar官方文档

我的环境

Visual Studio 2022
.NET Core 6.0

Nuget 安装

SqlSugarCore
在这里插入图片描述

新建连接串

在这里插入图片描述

public class DB_Helper{public SqlSugarScope Sqlserver { get; set; }public SqlSugarScope Mysql { get; set; }public SqlSugarScope Sqlite { get; set; }public DB_Helper(){Sqlserver = new SqlSugarScope(new ConnectionConfig(){DbType = DbType.SqlServer,ConnectionString = "server=网络地址;database=Test;uid=账号;pwd=密码",IsAutoCloseConnection = true,});Mysql = new SqlSugarScope(new ConnectionConfig(){DbType = DbType.MySql,ConnectionString = "server=localhost;user id = root;password = root;database = 数据表",IsAutoCloseConnection = true,});Sqlite = new SqlSugarScope(new ConnectionConfig(){DbType = DbType.Sqlite,ConnectionString = @"Datasource=文件地址",IsAutoCloseConnection = true,});}}

DB First 和 Code First使用

 internal class Program{private static DB_Helper dB_Helper; static void Main(string[] args){dB_Helper = new DB_Helper();//DB First,数据库文件创建，生成到Debug路径下dB_Helper.Sqlserver.DbFirst.IsCreateAttribute().CreateClassFile("SqlServer");dB_Helper.Mysql.DbFirst.IsCreateAttribute().CreateClassFile("Mysql");dB_Helper.Sqlite.DbFirst.IsCreateAttribute().CreateClassFile("Sqlite");//CodeFirst,用的不多。因为一般是先有数据库再有程序dB_Helper.Sqlserver.CodeFirst.InitTables<MySqlSugerTest>();dB_Helper.Mysql.CodeFirst.InitTables<MySqlSugerTest>();dB_Helper.Sqlite.CodeFirst.InitTables<MySqlSugerTest>();//增删改查这里不做赘述，可以去看官方文档Console.WriteLine("Hello, World!");}}
