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""
}
]
}
]
}";
我希望得到“alias”和“value”的值，如下面的json格式
[
{"address": "test"},
{"state": "test"}
]
那么，在json.net中是否有任何内置方法可以获取特定的属性值？
或者我是否需要在c＃中实现一些递归方法，它将在JObject中的所有JTokens和JArrays中按名称搜索JToken？ 有什么建议吗？
谢谢，

根据您在问题中显示的示例JSON，您应该能够得到您想要的结果：
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"]))));
