<>RedisSetService 类请参考第一篇的封装

redis 数据结构Set的使用
using (RedisSetService service = new RedisSetService()) { service.FlushAll();
//清理全部数据 service.Add("advanced", "111"); service.Add("advanced", "112"); service
.Add("advanced", "114"); service.Add("advanced", "114"); service.Add("advanced",
"115"); service.Add("advanced", "115"); service.Add("advanced", "113"); var
result= service.GetAllItemsFromSet("advanced"); var random = service.
GetRandomItemFromSet("advanced");//随机获取 service.GetCount("advanced");//独立的ip数
service.RemoveItemFromSet("advanced", "114"); { service.Add("begin", "111");
service.Add("begin", "112"); service.Add("begin", "115"); service.Add("end",
"111"); service.Add("end", "114"); service.Add("end", "113"); var result1 =
service.GetIntersectFromSets("begin", "end"); var result2 = service.
GetDifferencesFromSet("begin", "end"); var result3 = service.GetUnionFromSets(
"begin", "end"); } }
案例
//去重:IP统计去重;添加好友申请;投票限制;点赞; //交叉并的使用 using (RedisSetService service = new
RedisSetService()) { service.FlushAll();//清理全部数据 service.Add("XT", "Powell");
service.Add("XT", "Tenk"); service.Add("XT", "spider"); service.Add("XT",
"spider"); service.Add("XT", "spider"); service.Add("XT", "aaron"); service.Add(
"XT", "Linsan"); service.Add("Powell", "Eleven"); service.Add("Powell", "Tenk");
service.Add("Powell", "ywa"); service.Add("Powell", "Pang"); service.Add(
"Powell", "Jeff"); var result = service.GetIntersectFromSets("XT", "Powell");
var result2 = service.GetDifferencesFromSet("Powell", "XT"); var result3 =
service.GetDifferencesFromSet("XT", "Powell"); var result4=service.
GetUnionFromSets("XT", "Powell"); } /// <summary> /// 好友管理 共同好友-可能认识 /// 找出共同好友:
/// 关系型数据库:找出2个好友列表,然后再比对一下 /// 二次好友(可能认识): /// /// 既然是使用Redis
就尽可能的去使用Redis里面封装好的Api; /// </summary> public static void Show() { using (
RedisSetService service = new RedisSetService()) { service.FlushAll(); service.
Add("xut", "云怀"); service.Add("xut", "fresh"); service.Add("xut", "腾坤"); service
.Add("xut", "心有所属"); service.Add("xut", "莎士比亚"); service.Add("fresh", "奥利给");
service.Add("fresh", "明日梦"); service.Add("fresh", "棒棒糖"); service.Add("fresh",
"放下"); service.Add("fresh", "阳光下的微信"); service.Add("fresh", "腾坤"); //1.查询共同好友;
求交集 var resut1 = service.GetIntersectFromSets("xut", "fresh");// //2.好友推荐/可能认识人
var resut2 = service.GetDifferencesFromSet("fresh", "xut");// var resut3 =
service.GetDifferencesFromSet("xut", "fresh");// var result4 = service.
GetUnionFromSets("xut", "fresh"); } }
<>扩展版
using (RedisSetService service = new RedisSetService()) { //key--values service
.KeyFulsh(); service.Add("Advanced", "111"); service.Add("Advanced", "112");
service.Add("Advanced", "113"); service.Add("Advanced", "115"); service.Add(
"Advanced", "114"); service.Add("Advanced", "111"); service.Add("Begin", "111");
service.Add("Begin", "112"); service.Add("Begin", "113"); service.Add("Begin",
"117"); service.Add("Begin", "116"); service.Add("Begin", "111"); service.Add(
"Internal", "111"); service.Add("Internal", "112"); service.Add("Internal",
"117"); service.Add("Internal", "119"); service.Add("Internal", "118"); service.
Add("Internal", "111"); var result = service.GetAllItemsFromSet("Advanced"); var
result2= service.GetRandomItemFromSet("Advanced"); result = service.
GetAllItemsFromSet("Begin"); result2 = service.GetRandomItemFromSet("Begin");
var result3 = service.GetIntersectFromSets("Advanced", "Begin");//交 result3 =
service.GetDifferencesFromSet("Advanced", "Begin", "Internal");//差 result3 =
service.GetUnionFromSets("Advanced", "Begin", "Internal");//并 service.
RemoveItemFromSet("Advanced", "111"); result = service.GetAllItemsFromSet(
"Advanced"); service.RandomRemoveItemFromSet("Advanced"); result = service.
GetAllItemsFromSet("Advanced"); }
