Redis開發學習(4)_StackExchange.Redis_進行String相關操作




在一些資料整理上有提到雖然目前針對.NET
釋出相關Redis Client API  不只一個StackExchanged.Redis
但是ServiceStack是要付費的!!!!!!!
而且在舊新版本的切換上據說語法也會有不相容的問題



(1)資料塞入指令

寫法1.透過StringSet


1
IDatabaseObject.StringSet("Key","value");


寫法2.透過Execute方式


1
IDatabaseObject.Execute("SET", "Key", "Value");
