1、c#ioc 容器 unity ，簡單實用開頭先吐槽一下博客園超級不好用，添加圖片后就寫不動字了，難道是 bug好進入正題， 先來說下依賴注入， 簡單來說就是定義好接口， 上層代碼調用接口，具體實現通過配置文件方式去指定具體 實現類。首先我們需要通過 nuget 來安裝 unity安裝好后就可以寫一個方法類去實現依賴注入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);具體調用方法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"><!- 默認數據庫軟件類型：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 指定一個類的別名，<type type="IDatabase" mapTo="MySql"
