.net core中如何将同一个实例注入到2个不同的接口

Question

请问如何在.net core中如何将同一个实例注入到2个不同的接口?也就是将下面的MemcachedClient同时注入到IMemcachedClient与IDistributedCache：

services.Add(ServiceDescriptor.Singleton<IMemcachedClient, MemcachedClient>());

services.Add(ServiceDescriptor.Singleton<IDistributedCache, MemcachedClient>());

Answer 1

services.addSingleton<MemcachedClient,MemcachedClient>();services.addSingleton<IMemcachedClient,MemcachedClient>(sp=>sp.getservice<MemcachedClient>());services.addSingleton<IDistributedCache,MemcachedClient>(sp=>sp.getservice<MemcachedClient>());
