net 6 手动注入

Program.cs

 EnginContex为静态类

?

1 2	//注册服务 EnginContext.SetServiceProvider(app.Services);

EnginContex.cs

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

public sealed class EnginContext {     private static IServiceProvider _serviceProvider;       [MethodImpl(MethodImplOptions.Synchronized)]     public static void SetServiceProvider(IServiceProvider serviceProvider)     {         _serviceProvider = serviceProvider;     }       public static T Resolve<T>()     {         return _serviceProvider.GetService<T>();     } }

使用方法：

?

1 2 3 4 5 6 7 8

public sealed class T { public static T Instance => EnginContext.Resolve<T>(); }     ----------------  T.Instance.方法()
