前兩天冤家問我，有沒有運用過StackExchange.Redis，問我要個封裝類，由於之前都是運用ServiceStack.Redis，由於ServiceStack.Redis v4版本後是免費版的，所以如今也很有公司都在運用StackExchange.Redis而丟棄ServiceStack.Redis了。其實團體覺得，兩個驅動都不錯，只是由於ServiceStack.Redis免費招致目前很多公司都是基於V3版本的運用，也有人說V3版本有很多Bug，沒有維護和晉級，不過至多目前我是沒發現Bug。

不過ServiceStack.Redis同StackExchange.Redis比擬，拋開免費的來說，確認比StackExchange.Redis 更有優勢。StackExchange.Redis文檔很少，更不要說國際的文檔了，連github下面對應的引見文檔都是很片面，這點我真的覺得StackExchange.Redis的作者至多要完善下文檔，很多都是要看源碼的例子才有。網上對StackExchange.Redis的運用例子也比ServiceStack.Redis少得多，不是說沒人用，只是我查來查去，大局部都是基於String類型的數據停止運用的封裝類，關於List，SortedSet，Hash的封裝操作都很少，根本都是東寫一點，西寫一點，很難找到完好的。在參考了一些文章和源碼後，這裡提供一個自己封裝的類，根本提供關於各品種型的運用封裝，提供應大家學習運用，假如有哪裡寫的不好的，大家也可以相互交流。

ConnectionMultiplexer 封裝

首先是 ConnectionMultiplexer 的封裝，ConnectionMultiplexer對象是StackExchange.Redis最中樞的對象。這個類的實例需求被整個使用順序域共享和重用的，所以不需求在每個操作中不停的創立該對象的實例，普通都是運用單例來創立和寄存這個對象，這個在官網上也有闡明。

/// <summary>

 public static class RedisConnectionHelp
 {
  //零碎自定義Key前綴
  public static readonly string SysCustomKey = ConfigurationManager.AppSettings["redisKey"] ?? "";

  private static readonly string RedisConnectionString = ConfigurationManager.ConnectionStrings["RedisExchangeHosts"].ConnectionString;

  private static readonly object Locker = new object();
  private static ConnectionMultiplexer _instance;
  private static readonly ConcurrentDictionary<string, ConnectionMultiplexer> ConnectionCache = new ConcurrentDictionary<string, ConnectionMultiplexer>();

  /// <summary>

  public static ConnectionMultiplexer Instance
  {
   get
   {
    if (_instance == null)
    {
     lock (Locker)
     {
      if (_instance == null || !_instance.IsConnected)
      {
       _instance = GetManager();
      }
     }
    }
    return _instance;
   }
  }

  /// <summary>

  public static ConnectionMultiplexer GetConnectionMultiplexer(string connectionString)
  {
   if (!ConnectionCache.ContainsKey(connectionString))
   {
    ConnectionCache[connectionString] = GetManager(connectionString);
   }
   return ConnectionCache[connectionString];
  }

  private static ConnectionMultiplexer GetManager(string connectionString = null)
  {
   connectionString = connectionString ?? RedisConnectionString;
   var connect = ConnectionMultiplexer.Connect(connectionString);

   //注冊如下事情
   connect.ConnectionFailed += MuxerConnectionFailed;
   connect.ConnectionRestored += MuxerConnectionRestored;
   connect.ErrorMessage += MuxerErrorMessage;

RedisHelper 通用操作類封　　

public class RedisHelper
 {
  private int DbNum { get; }
  private readonly ConnectionMultiplexer _conn;
  public string CustomKey;

  #region 結構函數

  public RedisHelper(int dbNum = 0)
    : this(dbNum, null)
  {
  }

  public RedisHelper(int dbNum, string readWriteHosts)
  {
   DbNum = dbNum;
   _conn =
    string.IsNullOrWhiteSpace(readWriteHosts) ?
    RedisConnectionHelp.Instance :
    RedisConnectionHelp.GetConnectionMultiplexer(readWriteHosts);
  }

#region 輔佐辦法

  {
   var prefixKey = CustomKey ?? RedisConnectionHelp.SysCustomKey;
   return prefixKey + oldKey;

  {
   var database = _conn.GetDatabase(DbNum);
   return func(database);
  }

  private string ConvertJson<T>(T value)
  {
   string result = value is string ? value.ToString() : JsonConvert.SerializeObject(value);
   return result;
  }

  private T ConvertObj<T>(RedisValue value)
  {
   return JsonConvert.DeserializeObject<T>(value);
  }

  private List<T> ConvetList<T>(RedisValue[] values)
  {
   List<T> result = new List<T>();
   foreach (var item in values)
   {
    var model = ConvertObj<T>(item);
    result.Add(model);
   }
   return result;
  }

  private RedisKey[] ConvertRedisKeys(List<string> redisKeys)
  {
   return redisKeys.Select(redisKey => (RedisKey)redisKey).ToArray();
  }

}

其中CustomKey用來表示零碎前綴，AddSysCustomKey辦法對每個key都停止前綴的添加處置，這裡引薦大家在命名redis的key的時分最好的加上前綴，並且運用 ：來聯系前綴 ,這裡在運用可視化工具檢查的時分就比擬好區分，比方我的的前綴是 Demo:test:（普通是  零碎名：業務名：）,然後你檢查的時分你會發現劃一，好區分了很多

這裡說一下，StackExchange.Redis 中對對象的存儲是不自帶序列化和反序列化的辦法，所以在ConvertJson和ConvertObj外面我是運用了JsonConvert來操作，假如需求換成其他的序列化和序列化，直接修正這兩個方面就好了，另外，StackExchange.Redis 絕對於ServiceStack.Redis 來說提供了異步的辦法，所以這裡也異樣封裝了異步和同步的辦法。

以上就是對StackExchange.Redis根本操作的通用封裝，提供應大家學習參考，假如有哪裡寫錯的，也希望能一同交流。

問題：

StackExchange.Redis沒有提供Redis散布式鎖的操作麼？ServiceStack.Redis 提供了AcquireLock 的辦法來操作，StackExchange.Redis 源碼中只找到了LockTake的辦法，並沒有找到其他的辦法了，假如有人運用過，還希望能提供下。

最後，附上源碼地址：demo

以上就是本文的全部內容，希望對大家的學習有所協助，也希望大家多多支持。
