hiredis-dotnet is .NET redis client, supports .NETCore 2.1+, .NETFramework 4.0+, And Xamarin

• RedisClient Keep all method names consistent with redis-cli
• Support geo type commands (redis-server 3.2 or above is required)
• Support Redis Cluster
• Support Redis Sentinel
• Support Redis Master-Slave
• Supports stream type commands (requires redis-server 5.0 and above)
• Supports Redis 6 RESP3 Protocol

Single machine redis (单机)

public static RedisClient cli = new RedisClient("127.0.0.1:6379,password=123,defaultDatabase=13");

cli.Set("key1", "value1");
cli.MSet("key1", "value1", "key2", "value2");

string value1 = cli.Get("key1");
string[] vals = cli.MGet("key1", "key2");

Supports strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geo, streams And BloomFilter.

Parameter	Default	Explain
protocol	RESP2	If you use RESP3, you need redis 6.0 environment
user	<empty>	Redis server username, requires redis-server 6.0
password	<empty>	Redis server password
defaultDatabase	0	Redis server database
max poolsize	100	Connection max pool size
min poolsize	5	Connection min pool size
idleTimeout	20000	Idle time of elements in the connection pool (MS), suitable for connecting to remote redis server
connectTimeout	10000	Connection timeout (MS)
receiveTimeout	10000	Receive timeout (MS)
sendTimeout	10000	Send timeout (MS)
encoding	utf-8	string charset
ssl	false	Enable encrypted transmission
name	<empty>	Connection name, use client list command to view
prefix	<empty>	key前辍，所有方法都会附带此前辍，cli.Set(prefix + "key", 111);

IPv6: [fe80::b164:55b3:4b4f:7ce6%15]:6379

Master-Slave (读写分离)

public static cli = new RedisClient(
    "127.0.0.1:6379,password=123,defaultDatabase=13",
    "127.0.0.1:6380,password=123,defaultDatabase=13",
    "127.0.0.1:6381,password=123,defaultDatabase=13");

var value = cli.Get("key1");

写入时连接 127.0.0.1:6379，读取时随机连接 6380 6381

Redis Sentinel (哨兵高可用)

public static RedisClient cli = new RedisClient(
    "mymaster,password=123", 
    new [] { "192.169.1.10:26379", "192.169.1.11:26379", "192.169.1.12:26379" },
    true //是否读写分离
    );

Redis Cluster (集群)

假如你有一个 Redis Cluster 集群，其中有三个主节点(7001-7003)、三个从节点(7004-7006)，则连接此集群的代码：

var r = new RedisClient(new ConnectionStringBuilder[] { "192.168.0.2:7001", "192.168.0.2:7001", "192.168.0.2:7003" });

Scripting (脚本)

var r1 = cli.Eval("return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}", 
    new[] { "key1", "key2" }, "first", "second") as object[];

var r2 = cli.Eval("return {1,2,{3,'Hello World!'}}") as object[];

cli.Eval("return redis.call('set',KEYS[1],'bar')", 
    new[] { Guid.NewGuid().ToString() })

Pipeline (管道)

using (var pipe = cli.StartPipe())
{
    pipe.IncrBy("key1", 10);
    pipe.Set("key2", Null);
    pipe.Get("key1");

    object[] ret = pipe.EndPipe();
    Console.WriteLine(ret[0] + ", " + ret[2]);
}

// or Async Callback

using (var pipe = cli.StartPipe())
{
    var tasks = new List<Task>();
    long t0 = 0;
    task.Add(pipe.IncrByAsync("key1", 10).ContinueWith(t => t0 = t.Result)); //callback

    pipe.SetAsync("key2", Null);

    string t2 = null;
    task.Add(pipe.GetAsync("key1").ContinueWith(t => t2 = t.Result)); //callback

    pipe.EndPipe();
    Task.WaitAll(tasks.ToArray()); //wait all callback
    Console.WriteLine(t0 + ", " + t2);
}

Transaction (事务)

using (var tran = cli.Multi())
{
    tran.IncrBy("key1", 10);
    tran.Set("key2", Null);
    tran.Get("key1");

    object[] ret = tran.Exec();
    Console.WriteLine(ret[0] + ", " + ret[2]);
}

// or Async Callback

using (var tran = cli.Multi())
{
    var tasks = new List<Task>();
    long t0 = 0;
    task.Add(tran.IncrByAsync("key1", 10).ContinueWith(t => t0 = t.Result)); //callback

    tran.SetAsync("key2", Null);

    string t2 = null;
    task.Add(tran.GetAsync("key1").ContinueWith(t => t2 = t.Result)); //callback

    tran.Exec();
    Task.WaitAll(tasks.ToArray()); //wait all callback
    Console.WriteLine(t0 + ", " + t2);
}
