如何从以下 json.I 尝试但没有正确输出中获取标签值

Question

我已经试过了，但没有正确的反应。我有以下 json.I 想要在类型为 @type 时获取 rdfs:label 的值": "owl:DbType 并且 rdfs:class 被赋予任何 class (GreenPlant/GreenPlantHistory)

Ex : If @type": "owl:DbType and class is GreenPlant, fetch rdfs:label's value that is 'Involved' & 'Present'

我已经尝试按照 query.But 无法在 that.How 中添加 classname 来做到这一点。

查询：-

List<string> jp = v1.Where(i => (string)i["@type"] == "owl:DbType")
  .Select(i => (string)((JObject)i).Properties().First(x => x.Name == "rdfs:label").Value["@value"]).ToList();

{
  "@id": "Ap:Involved",
  "@type": "owl:DbType",
  "rdfs:class": {
    "@id": "Ap:GreenPlant"
  },
  "tag:std:label": {
    "@value": "Involved"
  },
  "rdfs:label": {
    "@value": "Involved"
  },
  "rdfs:range": {
    "@id": "xsd:boolean"
  }
},

{
  "@id": "Ap:Present",
  "@type": "owl:DbType",
  "rdfs:class": {
    "@id": "Ap:GreenPlant"
  },
  "tag:std:label": {
    "@value": "Present"
  },
  "rdfs:label": {
    "@value": "Present"
  },
  "rdfs:range": {
    "@id": "xsd:boolean"
  }
},

{
  "@id": "Ap:UserName",
  "@type": "owl:DbType",
  "rdfs:class": {
    "@id": "Ap:GreenPlantHistory"
  },
  "tag:std:label": {
    "@value": "UserName"
  },
  "rdfs:label": {
    "@value": "UserName"
  },
  "rdfs:range": {
    "@id": "xsd:string"
  }
},

{
  "@id": "Ap:Name",
  "@type": "owl:ObjType",
  "rdfs:class": {
    "@id": "Ap:GreenPlantHistory"
  },
  "tag:std:label": {
    "@value": "Name"
  },
  "rdfs:label": {
    "@value": "Name"
  },
  "rdfs:range": {
    "@id": "xsd:string"
  }
}

你的json无效，换成[]试试这个

var jsonParsed = JArray.Parse(json);
var found=FindValues(jsonParsed, "owl:DbType", "Ap:GreenPlant");

测试

Console.WriteLine(string.Join(",", found)); //Involved,Present

帮手

public List<string> FindValues(JArray jsonParsed, string strType , string strClass)
{
return jsonParsed.Where(i => (string)i["@type"] == strType 
       && (string)i["rdfs:class"]["@id"] == strClass)
    .Select(i => (string) i["rdfs:label"]["@value"]).ToList();
}
