Redis .Net 基本类型使用之南

前言

最近需要使用redis，看了一些文档，也在博客园里面看了很多文章，这里就记录下Redis常用类型的操作。

String

string是redis基本类型，一般通过Get，Set 命令进行操作，这里我用ServiceStack.Redis 进行操作：

using (redis)

{

    //setValue 插入数据

    redis.SetValue("hello", "world");

    string s = redis.GetValue("hello");

    redis.SetValue("Id", .ToString());

    long id = redis.IncrementValue("Id");

    id = redis.IncrementValueBy("Id", );

    redis.ExpireEntryIn("hello", new TimeSpan(, , ));

}

List

list就是我们提到的链表

using (redis)

{

    string listId = "listId";

    for (int i = ; i < ; i++)

    {

        redis.AddItemToList(listId, i.ToString());

    }

    string s = redis.GetItemFromList(listId, );

    List<string> all = redis.GetAllItemsFromList(listId);

    long count = redis.GetListCount(listId);

    s = redis.PopItemFromList(listId);

    s = redis.RemoveStartFromList(listId);

    s = redis.RemoveEndFromList(listId);

}

Set

set也是数据容器，和list不一样，set里面的元素不能重复

using (redis)

{

    string setId1 = "setId1";

    string setId2 = "setId2";

    for (int i = ; i < ; i++)

    {

        redis.AddItemToSet(setId1, i.ToString());

    }

    for (int i = ; i < ; i++)

    {

        redis.AddItemToSet(setId2, (i + ).ToString());

    }

    long count = redis.GetSetCount(setId1);

    string s = redis.GetRandomItemFromSet(setId1);

    HashSet<string> allIds = redis.GetAllItemsFromSet(setId1);

    HashSet<string> unionIds = redis.GetUnionFromSets(setId1, setId2);

    redis.StoreIntersectFromSets("intersectId", setId1, setId2);

    redis.StoreDifferencesFromSet("diffentsecId", setId1, setId2);

    allIds = redis.GetAllItemsFromSet("intersectId");

    allIds = redis.GetAllItemsFromSet("diffentsecId");

    redis.RemoveItemFromSet(setId1, "");

    s = redis.PopItemFromSet(setId1);

}

SortSet

SortSet和set一样，但sortset顾名思义就是有排序的set

using (redis)

{

    string sortSetId = "sortSetId";

    for (int i = ; i < ; i++)

    {

        redis.AddItemToSortedSet(sortSetId, i.ToString(), i);

    }

    bool contains = redis.SortedSetContainsItem(sortSetId, "");

    long count = redis.GetSortedSetCount(sortSetId);

    count = redis.GetSortedSetCount(sortSetId, , );

    List<string> ids = redis.GetAllItemsFromSortedSet(sortSetId);

    ids = redis.GetAllItemsFromSortedSetDesc(sortSetId);

    ids = redis.GetRangeFromSortedSet(sortSetId, , );

    ids = redis.GetRangeFromSortedSetByHighestScore(sortSetId, , );

    ids = redis.GetRangeFromSortedSetByLowestScore(sortSetId, , );

    double score = redis.GetItemScoreInSortedSet(sortSetId, "");

    IDictionary<string, double> valueWithScores = redis.GetRangeWithScoresFromSortedSet(sortSetId, , );

    valueWithScores = redis.GetRangeWithScoresFromSortedSetByHighestScore(sortSetId, , );

    valueWithScores = redis.GetRangeWithScoresFromSortedSetByLowestScore(sortSetId, , );

    bool isSucc = redis.RemoveItemFromSortedSet(sortSetId, "");

    count = redis.RemoveRangeFromSortedSet(sortSetId, , );

    count = redis.RemoveRangeFromSortedSetByScore(sortSetId, , );

    string s = redis.PopItemWithHighestScoreFromSortedSet(sortSetId);

    s = redis.PopItemWithLowestScoreFromSortedSet(sortSetId);

}

Hash

hash一般用来存储我们的对象模型

using (redis)

{

    string hashId = "hashId";

    bool isSucc = redis.SetEntryInHash(hashId, "Hello", "world");

    for (int i = ; i < ; i++)

    {

        redis.SetEntryInHash(hashId, i.ToString(), i.ToString());

    }

    long count = redis.GetHashCount(hashId);

    List<string> ids = redis.GetHashKeys(hashId);

    ids = redis.GetHashValues(hashId);

    isSucc = redis.HashContainsEntry(hashId, "Hello");

    string s = redis.GetValueFromHash(hashId, "Hello");

    ids = redis.GetValuesFromHash(hashId, "", "", "");

    isSucc = redis.RemoveEntryFromHash(hashId, "Hello");

    long afterInc = redis.IncrementValueInHash(hashId, "", );

    var newStringMap = new Dictionary<string, string> {

        {"","e"}, {"","f"}, {"","g"}};

    redis.SetRangeInHash(hashId, newStringMap);

}

总计

string，list， set, sortset, hash是redis的五种类型，这里只是简单的记录其基本操作
