Json反序列化

[zlp321002]

string result = "{\"image_id\": \"LZqkfgZdaRVzQvwqnCWwCQ==\", \"request_id\": \"1479872923803e24e2-2f93-4e02-86ef-94321d74d575\",\"time_used\": 310,\"\faces\":[{\"attributes\":{\"gender\": {\"value\": \"Female\"},\"age\": {\"value\": 20}},\"\face_rectangle\":{\"width\":180,\"top\":91,\"left\":272,\"height\":181},\"face_token\":\"ff48424df99df8543b3c89781483101f\"}]}";


myface datas = JsonConvert.DeserializeObject<myface>(result);

foreach (faces faceslist in datas.faces)
{
string ages = faceslist.attributes.age.value;
}

后面的值，为什么解析不到呢？

vs 编辑 选择性黏贴 你的 json 看一下生成的Model类就可以了

[巴士上的邂逅]

你的字符串应该有问题，注意标红处 string result = "{\"image_id\": \"LZqkfgZdaRVzQvwqnCWwCQ==\", \"request_id\": \"1479872923803e24e2-2f93-4e02-86ef-94321d74d575\",\"time_used\": 310,\"\faces\":[{\"attributes\":{\"gender\": {\"value\": \"Female\"},\"age\": {\"value\": 20}},\"\face_rectangle\":{\"width\":180,\"top\":91,\"left\":272,\"height\":181},\"face_token\":\"ff48424df99df8543b3c89781483101f\"}]}";

我这么解析的，不知道为什么解析不了？楼上的二位！

2楼描述应该正确，你应该先看看你的json串是否正确。 然后才开始做解析的步骤。http://tool.oschina.net/codeformat/json http://blog.csdn.net/lutaotony/article/details/50460836 不知道是不是你想要的
