Asp.Net Core中注入泛型接口的依赖项

1、扩展批量注入类

<span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">static</span> <span style="color: rgba(0, 0, 255, 1);">class</span><span style="color: rgba(0, 0, 0, 1);"> ServicesExtersion

                    }
                }
            });
        }

        </span><span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">static</span> List<TypeInfo> GetTypesAssignableTo(<span style="color: rgba(0, 0, 255, 1);">this</span><span style="color: rgba(0, 0, 0, 1);"> Assembly assembly, Type compareType)

        }
    }</span>

public static class ServicesExtersion

{

public static void AddClassesAsImplementedInterface(

this IServiceCollection services

, Assembly assembly

, Type compareType

{

{

foreach (var implementedInterface in type.ImplementedInterfaces)

switch (lifetime)

}

2、Startup注入

<span style="color: rgba(0, 128, 0, 1);">//</span><span style="color: rgba(0, 128, 0, 1);"> 注入泛型依赖项</span>
            services.AddClassesAsImplementedInterface(Assembly.Load(<span style="color: rgba(128, 0, 0, 1);">"</span><span style="color: rgba(128, 0, 0, 1);">WebApplication2</span><span style="color: rgba(128, 0, 0, 1);">"</span>), <span style="color: rgba(0, 0, 255, 1);">typeof</span>(IServices<>));

// 注入泛型依赖项

services.AddClassesAsImplementedInterface(Assembly.Load("WebApplication2"), typeof(IServices<>));

3、接口实现类

<span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">class</span><span style="color: rgba(0, 0, 0, 1);"> User

        }

    }

        }

        </span><span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">async</span> Task<Role><span style="color: rgba(0, 0, 0, 1);"> GetObj()

        }
    }

 </span><span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">interface</span> IServices<T><span style="color: rgba(0, 0, 0, 1);">

public class User

}

public class Role

{

}

public class UserServices: IServices<User>

{

public async Task<string> GetData()

return await Task.FromResult("User服务实现类");

}

public async Task<User> GetObj()

{

return await Task.FromResult(new User());

}

}

public async Task<Role> GetObj()

{

}

public interface IServices<T>

}

4、controll控制器实现

<span style="color: rgba(0, 0, 255, 1);">public</span> <span style="color: rgba(0, 0, 255, 1);">class</span><span style="color: rgba(0, 0, 0, 1);"> HomeController : Controller

            }

            {

        }
    }</span>

public class HomeController : Controller

{

private readonly ILogger<HomeController> _logger;
