(精华)2020年8月16日 redis数据库 StackExchange.Redis中ZSet类型(C#版)

RedisZSetService 类请参考第一篇的封装

redis 数据结构ZSet的使用

using (RedisZSetService service = new RedisZSetService())
{
     
service.FlushAll();//清理全部数据

service.Add("advanced", "1");
service.Add("advanced", "2");
service.Add("advanced", "5");
service.Add("advanced", "4");
service.Add("advanced", "7");
service.Add("advanced", "5");
service.Add("advanced", "9");

var result1 = service.GetAll("advanced");
var result2 = service.GetAllDesc("advanced");

service.AddItemToSortedSet("Sort", "BY", 123234);
service.AddItemToSortedSet("Sort", "走自己的路", 123);
service.AddItemToSortedSet("Sort", "redboy", 45);
service.AddItemToSortedSet("Sort", "大蛤蟆", 7567);
service.AddItemToSortedSet("Sort", "路人甲", 9879);
var result3 = service.GetAllWithScoresFromSortedSet("Sort");
}
