redis研究之watch

具体的看注释，代码如下：

         public static void TransTest()
         {
             RedisClient client1 = new RedisClient(host, port);
             RedisClient client2 = new RedisClient(host, port);
             //初始k1为1
             client1.Set<string>("k1", "");
             Console.WriteLine(client1.Get<string>("k1"));
             //监视k1
             client1.Watch("k1");
             var trans = client1.CreateTransaction();
             trans.QueueCommand(r => r.Set<string>("k1", ""));
             //k2不存在
             trans.QueueCommand(r => r.Set<string>("k2", ""));
             //其它客户端在事务提交前修改k1的值
             client2.Set<string>("k1", "AAAAAAAAAA");
             //提交事务
             trans.Commit();
             Console.WriteLine(client1.Get<string>("k1"));//这里会输出AAAAAAAAAA
             Console.WriteLine(client1.Get<string>("k2"));//这个值会是空
             Console.Read();
         }
