我有Jobject，例如：
string json = @"
{
""memberdetails"": [
{
""id"": 0,
""label"": ""General Details"",
""visible"": true,
""properties"": [
{
""label"": ""Address"",
""description"": ""Residential or Postal Address"",
""view"": ""textarea"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": ""test 1"",
""alias"": ""address"",
""editor"": ""Umbraco.TextboxMultiple"",
""visible"": ""true""
},
{
""label"": ""State"",
""description"": ""State of residence"",
""view"": ""textbox"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": ""test 2"",
""alias"": ""state"",
""editor"": ""Umbraco.Textbox"",
""visible"": ""true""
}
]
},
{
""id"": 1,
""label"": ""Other Details"",
""visible"": true,
""properties"": [
{
""label"": ""Address"",
""description"": ""Residential or Postal Address"",
""view"": ""textarea"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": ""test_otherdetails1 "",
""alias"": ""address"",
""editor"": ""Umbraco.TextboxMultiple"",
""visible"": ""true""
},
{
""label"": ""State"",
""description"": ""State of residence"",
""view"": ""textbox"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": ""test_otherdetails2"",
""alias"": ""state"",
""editor"": ""Umbraco.Textbox"",
""visible"": ""true""
}
]
},
{
""id"": 2,
""label"": "" Details"",
""visible"": true,
""properties"": [
{
""label"": ""Address"",
""description"": ""Residential or Postal Address"",
""view"": ""textarea"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": "" Details1"",
""alias"": ""address"",
""editor"": ""Umbraco.TextboxMultiple"",
""visible"": ""true""
},
{
""label"": ""State"",
""description"": ""State of residence"",
""view"": ""textbox"",
""config"": {},
""hideLabel"": false,
""validation"": {
""mandatory"": false,
""pattern"": null
},
""id"": 0,
""value"": ""Details1"",
""alias"": ""state"",
""editor"": ""Umbraco.Textbox"",
""visible"": ""true""
}
]
}
]
}";
我想得到"alias"one_answers"value"的值，如下json格式
[
{"address": "test"},
{"state": "test"}
]
那么，在json.net中有没有内置的方法可以让我获得特定的属性值呢？
或者我需要在c#中实现一些递归方法，该方法将在JObject中的所有JToken和JArray中按名称搜索JToken？有什么建议吗？
谢谢，
基于您在问题中显示的示例JSON，您应该能够得到您想要的结果，如下所示：
JObject obj = JObject.Parse(json);
JArray result = new JArray(
obj.SelectToken("memberdetails[0].properties")
.Select(jt => new JObject(new JProperty((string)jt["alias"],jt["value"]))));
