反序列化问题
我必须制作一个使用照片返回年龄的程序，我正在使用 Azure 的faceApi 服务。
它返回下面的代码
[
{
"faceId": "f7eda569-4603-44b4-8add-cd73c6dec644",
"faceRectangle": {
"top": 131,
"left": 177,
"width": 162,
"height": 162
},
"faceAttributes": {
"smile": 0.0,
"headPose": {
"pitch": 0.0,
"roll": 0.1,
"yaw": -32.9
},
"gender": "female",
"age": 22.9,
"facialHair": {
"moustache": 0.0,
"beard": 0.0,
"sideburns": 0.0
},
"glasses": "NoGlasses",
"emotion": {
"anger": 0.0,
"contempt": 0.0,
"disgust": 0.0,
"fear": 0.0,
"happiness": 0.0,
"neutral": 0.986,
"sadness": 0.009,
"surprise": 0.005
},
"blur": {
"blurLevel": "low",
"value": 0.06
},
"exposure": {
"exposureLevel": "goodExposure",
"value": 0.67
},
"noise": {
"noiseLevel": "low",
"value": 0.0
},
"makeup": {
"eyeMakeup": true,
"lipMakeup": true
},
"accessories": [
],
"occlusion": {
"foreheadOccluded": false,
"eyeOccluded": false,
"mouthOccluded": false
},
我更改了代码以减少它，因为我只需要年龄。现在输出是这样的
[{"faceId":"b2342836-6d99-4f69-b656-1a64b786b421","faceRectangle":{"top":60,"left":52,"width":58,"height":58},"faceAttributes":{"age":40.0}}]
我认为一切都是正确的，但是每当我尝试反序列化时都会返回一个对象 null。例如我尝试过使用这个
Analysis dsjson = new JavaScriptSerializer().Deserialize<Analysis>(contentString);
有人可以帮我解决这个问题吗？
提前致谢。

您可以使用该Newtonsoft库，它是 .NET 的流行高性能 JSON 框架。您可以在这里阅读更多相关信息关于您的JSON字符串，使用这个包将产生您想要的结果。Model请参阅以下由类和反序列化过程组成的代码：using System;using Newtonsoft.Json;using System.Collections.Generic;public class Program{ public static void Main() { string json=@"[{'faceId':'f7eda569-4603-44b4-8add-cd73c6dec644','faceRectangle':{'top':131,'left':177,'width':162,'height':162},'faceAttributes':{'smile':0,'headPose':{'pitch':0,'roll':0.1,'yaw':-32.9},'gender':'female','age':22.9,'facialHair':{'moustache':0,'beard':0,'sideburns':0},'glasses':'NoGlasses','emotion':{'anger':0,'contempt':0,'disgust':0,'fear':0,'happiness':0,'neutral':0.986,'sadness':0.009,'surprise':0.005},'blur':{'blurLevel':'low','value':0.06},'exposure':{'exposureLevel':'goodExposure','value':0.67},'noise':{'noiseLevel':'low','value':0},'makeup':{'eyeMakeup':true,'lipMakeup':true},'accessories':[],'occlusion':{'foreheadOccluded':false,'eyeOccluded':false,'mouthOccluded':false},'hair':{'bald':0,'invisible':false,'hairColor':[{'color':'brown','confidence':1},{'color':'black','confidence':0.87},{'color':'other','confidence':0.51},{'color':'blond','confidence':0.08},{'color':'red','confidence':0.08},{'color':'gray','confidence':0.02}]}}}]"; var Sresponse = JsonConvert.DeserializeObject<List<RootObject>>(json); foreach(var result in Sresponse) { //Get your data here from the deserialization Console.WriteLine(result.faceId); Console.WriteLine(result.faceRectangle.height); Console.WriteLine(result.faceAttributes.emotion.disgust); } }}public class FaceRectangle{ public int top { get; set; } public int left { get; set; } public int width { get; set; } public int height { get; set; }}public class HeadPose{ public double pitch { get; set; } public double roll { get; set; } public double yaw { get; set; }}public class FacialHair{ public double moustache { get; set; } public double beard { get; set; } public double sideburns { get; set; }}public class Emotion{ public double anger { get; set; } public double contempt { get; set; } public double disgust { get; set; } public double fear { get; set; } public double happiness { get; set; } public double neutral { get; set; } public double sadness { get; set; } public double surprise { get; set; }}public class Blur{ public string blurLevel { get; set; } public double value { get; set; }}public class Exposure{ public string exposureLevel { get; set; } public double value { get; set; }}public class Noise{ public string noiseLevel { get; set; } public double value { get; set; }}public class Makeup{ public bool eyeMakeup { get; set; } public bool lipMakeup { get; set; }}public class Occlusion{ public bool foreheadOccluded { get; set; } public bool eyeOccluded { get; set; } public bool mouthOccluded { get; set; }}public class HairColor{ public string color { get; set; } public double confidence { get; set; }}public class Hair{ public double bald { get; set; } public bool invisible { get; set; } public List<HairColor> hairColor { get; set; }}public class FaceAttributes{ public double smile { get; set; } public HeadPose headPose { get; set; } public string gender { get; set; } public double age { get; set; } public FacialHair facialHair { get; set; } public string glasses { get; set; } public Emotion emotion { get; set; } public Blur blur { get; set; } public Exposure exposure { get; set; } public Noise noise { get; set; } public Makeup makeup { get; set; } public List<object> accessories { get; set; } public Occlusion occlusion { get; set; } public Hair hair { get; set; }}public class RootObject{ public string faceId { get; set; } public FaceRectangle faceRectangle { get; set; } public FaceAttributes faceAttributes { get; set; }}输出：f7eda569-4603-44b4-8add-cd73c6dec6441620
