Redis筆記-數據類型-Hash 使用範例

介紹簡單的使用
語言:c#
使用函式庫:StackExchange.Redis

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

//設定連線字串 using (ConnectionMultiplexer conn = ConnectionMultiplexer.Connect("127.0.0.1:10001")) {     // 取得操作介面     IDatabase cache = conn.GetDatabase();       const string custKey1 = "Key1";       // 先刪除該Key以確保這個key對應資料型態是全新的     cache.KeyDeleteAsync(custKey1);       // 設定值     cache.HashSetAsync(custKey1, "abc", "def");     cache.HashSetAsync(custKey1, "ghi", "jkl");     cache.HashSetAsync(custKey1, "mno", "pqr");       // 依照custKey1取得對應hash值     HashEntry[] tResult = cache.HashGetAll(custKey1);     foreach (HashEntry tHE in tResult)     {         Console.WriteLine(tHE.Name + ":" + tHE.Value);     } }

我們也可以使用HashSet() 一次設定好Hash的值

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

//設定連線字串 using (ConnectionMultiplexer conn = ConnectionMultiplexer.Connect("127.0.0.1:10001")) {     // 取得操作介面     IDatabase cache = conn.GetDatabase();       const string custKey1 = "Key1";       // 先刪除該Key以確保這個key對應資料型態是全新的     cache.KeyDeleteAsync(custKey1);       // 設定值     HashEntry[] hashEntries =         {             new HashEntry("abc", "def"),             new HashEntry("ghi", "jkl"),             new HashEntry("mno", "pqr"),         };     cache.HashSet(custKey1, hashEntries);       // 依照custKey1取得對應hash值     HashEntry[] tResult = cache.HashGetAll(custKey1);     foreach (HashEntry tHE in tResult)     {         Console.WriteLine(tHE.Name + ":" + tHE.Value);     } }

以下為使用搜索範例

?

1 2 3 4 5 6 7 8 9 10

// 搜索這個key的所有內容 IEnumerable<hashentry> t1 = cache.HashScan(custKey1); HashEntry[] v1 = t1.ToArray();                   Console.WriteLine("==HashScan(custKey1)=="); foreach (HashEntry tHE in v1) {     Console.WriteLine(tHE.Name + ":" + tHE.Value); } </hashentry>

條件過濾

?

1 2 3 4 5 6 7 8 9 10

// 加條件的過濾搜索 IEnumerable<hashentry> t2 = cache.HashScan(custKey1, "*h*"); HashEntry[] v2 = t2.ToArray();   Console.WriteLine("==HashScan(custKey1,'*h*')=="); foreach (HashEntry tHE in v2) {     Console.WriteLine(tHE.Name + ":" + tHE.Value); } </hashentry>
