在说StackExchange.Redis 的时候说了，因为我们的项目一直.net4.0不升级，没有办法，我说的不算，哈哈，又查了StackExchange.Redis在.net4.0使用麻烦，所以选了NServiceKit.Redis。结构也不说了，直接上代码了。
ICache.cs
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ClassLibrary2 { public interface ICache { object Get(string key); T GetT<T>(string key) where T : class; object GetWithDelete(string key); T GetWithDelete<T>(string key) where T : class; bool Set(string key, object value); bool Set(string key, object value, DateTime expireDate); bool SetT<T>(string key, T value) where T : class; bool SetT<T>(string key, T value, DateTime expire) where T : class; bool Remove(string key); } }
