在单个调用中获取许多SET的示例C＃代码如下：我使用StackExchange.Redis作为Redis连接器：
using StackExchange.Redis;using System;using System.Text;namespace RedisGetMultipleKeys{/// <summary>/// Class to perofrme operations on SE.Redis/// </summary>class Program{ /// <summary> /// Executes necessary pre-requisites /// </summary> /// <param name="args"></param> static void Main(string[] args) { //Connect Redis var _cache = Program.Connect(); //Store 10k Sets string prefix = "user"; StringBuilder keys = new StringBuilder(); for (int i = 0; i < 10000; i++) { keys.Append(" " + prefix + i); _cache.SetAdd(prefix + i, i); } var keyList = new RedisKey[10000]; //Generate keys array for (int i = 0; i < 10000; i++) { var key = new RedisKey(); key = prefix + i; keyList.SetValue(key, i); } var startTime = DateTime.Now; //Perform SUNIOn var values = _cache.SetCombine(SetOperation.Union, keyList); var endTime = DateTime.Now; TimeSpan diff = endTime.Subtract(startTime); Console.WriteLine("total time taken to read 10k keys = " + diff); Console.Read(); //TODO: to be changed accordingly to read Set values returned other than String foreach (var value in values) { Console.WriteLine(value.ToString()); } endTime = DateTime.Now; diff = endTime.Subtract(startTime); Console.WriteLine("total time taken to read 10k keys = " + diff); Console.Read(); } /// <summary> /// Connects to Redis db /// </summary> /// <returns>Returns an instance of Redis db</returns> private static IDatabase Connect() { string redisConnection = "localhost:6379,ssl=false,allowAdmin=true,ConnectRetry=3,ConnectTimeout=5000,defaultDatabase=1"; ConnectionMultiplexer connection = ConnectionMultiplexer.Connect(redisConnection); return connection.GetDatabase(); }}}
我希望它能帮助C＃开发人员寻找解决方案。由于Mgravell从SE.Redis开发团队由他的建议帮助我。在GitHub上可以找到更多讨论，如何通过在单个调用中传递集合密钥列表来获取多个集合
