Question

如何用ServiceStack.Redis 操作多个节点

Answer 1

使用IRedisClient执行事务示例：

using (IRedisClient RClient = prcm.GetClient())
{
RClient.Add("key",1);
using (IRedisTransaction IRT = RClient.CreateTransaction())
{
IRT.QueueCommand(r => r.Set("key", 20));
IRT.QueueCommand(r => r.Increment("key",1));

IRT.Commit(); // 提交事务
}
Response.Write(RClient.Get<string>("key"));
}

二、并发锁

使用IRedisClient申请锁示例：

using (IRedisClient RClient = prcm.GetClient())
{
RClient.Add("mykey",1);
// 支持IRedisTypedClient和IRedisClient
using (RClient.AcquireLock("testlock"))
{
Response.Write("申请并发锁<br/>");
var counter = RClient.Get<int>("mykey");

Thread.Sleep(100);

RClient.Set("mykey", counter + 1);
Response.Write(RClient.Get<int>("mykey"));
}
}
