使用Linq对JSON对象进行排序

Question

我收到了来自Google Search Appliance的回复,建议采用以下格式的JSON形式的服务

string jsonString = @"{ ""query"": ""t"", ""results"": [ { ""name"": ""tom"", ""type"": ""suggest"" }, { ""name"": ""tim"", ""type"": ""suggest"" }]}";

我想按字母顺序对结果列表进行排序,并将名称更改为句子大小写.我可以在jquery中执行此操作,但出于性能原因,它更愿意在服务器端执行此操作.

我可以对结果进行排序但返回IEnumarable<Result>但我似乎无法对正在序列化的对象中的结果进行排序.

 string jsonString = @"{ ""query"": ""t"", ""results"": [ { ""name"": ""tom"", ""type"": ""suggest"" }, { ""name"": ""tim"", ""type"": ""suggest"" }]}";

JObject json = JObject.Parse(jsonString);

        var gsaSuggestions = JsonConvert.DeserializeObject<GSASuggestion>(jsonString);

        var orded = gsaSuggestions.ResultList.OrderBy<Result, string>(r => r.Name);

        string output = JsonConvert.SerializeObject(gsaSuggestions);
    }

    [JsonObject(MemberSerialization.OptOut)]
    public class GSASuggestion
    {
        [JsonProperty(PropertyName = "query")]
        public string Query {get; set;}
        [JsonProperty(PropertyName = "results")]
        public List<Result> ResultList {get; set;}
    }

    public class Result
    {
        [JsonProperty(PropertyName = "name")]
        public string Name {get; set;}
        [JsonProperty(PropertyName = "type")]
        public string Type {get; set;}
    }

结果应该是:

{ "query": "t", "results": [ { "name": "Tim", "type": "suggest" }, { "name": "Tom", "type": "suggest" }]};

Answer 1

您实际上并未使用OrderBy的返回值.尝试:

gsaSuggestions.ResultList =
    gsaSuggestions.ResultList.OrderBy<Result, string>(r => r.Name).ToList();

请记住,OrderBy按顺序返回包含结果的新序列,并且不会修改原始序列.如果要gsaSuggestions.ResultList进行排序,则需要为其分配排序列表.

您还可以使用List.Sort进行就地排序:

gsaSuggestions.ResultList.Sort((x, y) => x.Name.CompareTo(y.Name));
