c#使用 NServiceKit.Redis 封装 RedisHelper

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.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);
    }
}
