KVStore的简单介绍
阿里云KVStore兼容Redis。因为KVStore就相当于Redis的服务器端，我们代码只是当作客户端，链接上服务器端就行了，阿里云的KVStore详情文档见，https://docs.aliyun.com/#/pub/kvstore/key-value-store/kvstore-introduction。
C#客户端链接OCS
1.阿里云文档上介绍的是用ServiceStack去链接KVStore。那我们项目中就用nuget去下载ServiceStack包。nuget搜索ServiceStack，搜索到的结果如下图，安装图中标识的就可以了。这个应该是最新的V4版本，当提醒你需要用商业版的时候，可以去还原之前的V3版本，具体还原方法见，https://github.com/ServiceStackV3/ServiceStackV3。
nuget搜索结果如下：
2.安装好以后，写链接和调用kvstore的代码。其中_setting.AccessId, _setting.AccessKey, _setting.HostAddress，分别是KVStore的实例ID，链接密码和链接地址。
