c#ioc容器unity,简单实用

1、c#ioc 容器 unity ，简单实用开头先吐槽一下博客园超级不好用，添加图片后就写不动字了，难道是 bug好进入正题， 先来说下依赖注入， 简单来说就是定义好接口， 上层代码调用接口，具体实现通过配置文件方式去指定具体 实现类。首先我们需要通过 nuget 来安装 unity安装好后就可以写一个方法类去实现依赖注入public class UnityIocHelper : IServiceProviderprivate readonly IUnityContainer _container;private static readonly UnityIocHelper dbinstance

2、=new UnityIocHelper("DBcontainer");private UnityIocHelper(string containerName)UnityConfigurationSection section =(UnityConfigurationSection)ConfigurationManager.GetSection( "unity");_container = new UnityContainer();section.Configure(_container, containerName);public static Unit

3、yIocHelper DBInstanceget return dbinstance; public object GetService(Type serviceType)return _container.Resolve(serviceType);public T GetService<T>()return _container.Resolve<T>();public T GetService<T>(paramsParameterOverride obj)return _container.Resolve&a

4、mp;lt;T>(obj);public T GetService<T>(string name, paramsParameterOverride obj)return _container.Resolve<T>(name, obj);具体调用方法public static IDatabase Base(string connString)returnMyUnityIocHelper.DBInstance.GetService<IDatabase>(Sql ”, new ParameterOver

5、ride("connString", connString);配置信息<unity><typeAliases><typeAlias alias="IDatabase"type="LRMC.Data.IDatabase,LRMC.Data" /><typeAlias alias="SqlServer"type="LRMC.Data.SqlDapper.Database,LRMC.Data.SqlDapper &

6、quot; /><typeAlias alias="MySql"type="LRMC.Data.MySqlDapper.Database,LRMC.Data.MySqlDapper" /></typeAliases><containers><container name="DBcontainer"><!- 默认数据库软件类型：SqlServer,MySql,Oracle,Access,SQLite

7、-><type type="IDatabase" mapTo="SqlServer"name="SqlServer"></type ><type type="IDatabase" mapTo="MySql"name="MySql"></type ></container></containers></unity>typeAlias 指定一个类的别名，<type type="IDatabase" mapTo="MySql"
