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);
