国产优秀ORM框架SqlSugar的使用方法，实例解析
SqlSugar是一个轻量级ORM框架，专门用于.NET平台，可以简化数据库操作，提高开发效率。它支持多种数据库，包括MySQL、SqlServer、Oracle等，提供了丰富的功能和灵活的配置选项。下面将详细介绍SqlSugar的使用方法及其相比其他ORM框架的优点。
一、SqlSugar的安装和配置
1.使用NuGet包管理器安装SqlSugar。<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>在Visual<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>Studio中，右击项目，选择“管理NuGet程序包”，搜索“SqlSugar”，选择安装。
2.配置数据库连接字符串。<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>在app.config或web.config文件中，添加如下配置节：
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>3.创建实体类。<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>创建一个类，用于映射数据库表的结构，例如：
public<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>class<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>User{<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=127.0.0.1;Initial Catalog=TestDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings><connectionStrings>
