1.引用Nuget包 ServiceStack.Redis
我这里就用别人已经封装好的Reids操作类来和大家一起参考了下,看看怎么使用ServiceStack.Redis 操作Redis数据
RedisConfigInfo--redis配置文件信息
代码语言:javascript复制 /// <summary>

public sealed class RedisConfigInfo

RedisManager --Redis管理中心 创建Redis链接

new RedisClientManagerConfig

});
}

RedisBase-- 是redis操作的基类,继承自IDisposable接口,主要用于释放内存

irt.Rollback();

nuget包是外国人写的,在国内并没有完整的中文文档,也没有专门的人来翻译、封装它,所以上面的代码方法不是很全,还有很多api方法需要自己去官网找然后自己封装。
在这里,上面的封装我就放一边,还是给大家演示ServiceStack原生的API如何使用
2. string 类型的使用
代码语言:javascript复制 public static RedisClient client = new RedisClient("127.0.0.1", 6379);
//1.存入键值对
bool a = client.Set("key_name", "value_11");
//2. 根据key获取值
string data1= client.GetValue("key_name");
//3. 在原有的value上进行追加
long data2 = client.AppendToValue("key_name", "value_11");
// 4.获取值的长度
var data3=client.GetStringCount("key_name");
//5. 数值自增/减,返回自增、自减后的值
client.Set("小明分数", 100);
//自增20,可以自增负值
var data4= client.IncrementValueBy("小明分数", 20);
//自减50
var data5 = client.DecrementValueBy("小明分数", 50);
//6. 插入实体和读取实体
UserInfo userInfo = new UserInfo() { Id = 3, Age = 50, Name = "zxl", Pwd = "123456" };
client.Set("UserInfo_Id_3", userInfo);
UserInfo data6 = client.Get<UserInfo>("UserInfo_Id_3");
//7. 一次性添加多个key-value集合
Dictionary<string, string> dic = new Dictionary<string, string>() {
{ "101", Guid.NewGuid().ToString("N")},
{ "102", Guid.NewGuid().ToString("N")},
{ "103", Guid.NewGuid().ToString("N")},
{ "104", Guid.NewGuid().ToString("N")},
{ "105", Guid.NewGuid().ToString("N")},
{ "106", Guid.NewGuid().ToString("N")}
};
client.SetAll(dic);
//8.获取多个key的 value值集合
List<string> keys = new List<string>(){ "101", "103", "105" };
List<string> data8= client.GetValues(keys);
代码语言:javascript复制 //9. 重命名key
client.Rename("106", "1066");
//10. 设置key的过期时间(30秒后自动销毁)
bool b2= client.Expire("102", 30);
//11. 删除单个key
bool d1 = client.Remove("101");//删除成功,返回true
bool d2 = client.Remove("ffff"); //删除不存在的数据,返回false
代码语言:javascript复制//12. 删除多个key
IEnumerable<string> delete_keys = new List<string> { "101", "103", "105" };
client.RemoveAll(delete_keys);
代码语言:javascript复制//13.清除全部数据 请小心
client.FlushAll();
