[英]deserialize json to object c# on windows phone
我正在尝试将从Web服务器收到的json数据服务反序列化为对象。 到目前为止,我刚刚建立了一个httpwebrequest,它从服务器获取json fromatted数据。
public void DoHttpWebRequest(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.BeginGetResponse(new AsyncCallback(onGetResponse), request);
}
public void onGetResponse (IAsyncResult asyncResult)
{
HttpWebRequest myRequest = (HttpWebRequest)asyncResult.AsyncState;
HttpWebResponse myResponse = (HttpWebResponse)myRequest.EndGetResponse(asyncResult);
using (StreamReader httpwebStreamReader = new StreamReader(myResponse.GetResponseStream()))
{
string results = httpwebStreamReader.ReadToEnd();
Dispatcher.BeginInvoke(() => textBlock5.Text = results);
}
myResponse.Close();
}
这将返回以下数据。
{"BodyStyle":"Sports","ChassisNumber":19316,"Colour":"Ivory","Condition":"Showroom","Model":"Silver Wraith","Owners":[{"DateBought":"\/Date(-207269643940+0100)\/","DateSold":"\/Date(-113297981580+0100)\/","ID":651,"Owner":{"Address":null,"Decorations":null,"Email":"jvcuejnj.ldmfkiftvh@wx-sts.net","Forename":"Ismael","ID":637,"Mobile":"008547-4461","Surname":"Anderson","Telephone":"366892-9004","Title":"Mr"}}],"RegistrationNumber":"RB4107 ","Year":1909}
如何使用DataContractJsonSerializer将数据解析为具有以下类的对象?
public class CarOwnershipRecord {
public int? ID{ get; set; }
public DateTime? DateBought{ get; set; }
public DateTime? DateSold{ get; set; }
public Person Owner{ get; set; }
}
public class Car {
public string BodyStyle{ get; set; }
public short? ChassisNumber{ get; set; }
public string Colour{ get; set; }
public string Condition{ get; set; }
public string Model{ get; set; }
public List<CarOwnershipRecord> Owners{ get; set; }
public string RegistrationNumber{ get; set; }
public short Year{ get; set; }
}
public class CarPhoto {
public string RegistrationNumber{ get; set; }
public byte[] Photo{ get; set; }
// The Photo field contains the binary contents of an image file
}
这样的事情会给你正确的结果:
byte[] data = Encoding.UTF8.GetBytes(jsonString);
MemoryStream memStream = new MemoryStream(data);
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(Car));
Car car = (Car) serializer.ReadObject(memStream);
虽然如果要跳过MemoryStream部分,可以直接从响应流反序列化
