本文主要介绍Newtonsoft.JSON(Json.NET)中,将一个对象的Json字符串反序化成两个不同的实体对象的方法代码。具体效果如下:

Json字符串

[{
"guardian_id": "1453",
"guardian_name": "Foo Bar",
"patient_id": "938",
"patient_name": "Foo Bar",
}]

反序列化成的两个Model实例对象

class Guardian {
[JsonProperty(PropertyName = "guardian_id")]
public int ID { get; set; }
[JsonProperty(PropertyName = "guardian_name")]
public int Name { get; set; }
}

class Patient {
[JsonProperty(PropertyName = "patient_id")]
public int ID { get; set; }
[JsonProperty(PropertyName = "patient_name")]
public int Name { get; set; }
}

1、分别反序化成实体(model)对象

string json = @"[{'guardian_id':'1453','guardian_name':'Foo Bar','patient_id':'938','patient_name':'Foo Bar'}]";
var guardians = JsonConvert.DeserializeObject<List<Guardian>>(json);
var patients = JsonConvert.DeserializeObject<List<Patient>>(json);

2、通过Pair类反序化

反序化一次就可以实现

Pair类如下

public class Pair
{
public Pair()
{
Guardian = new Guardian();
Patient = new Patient();
}
[JsonIgnore]
public Guardian Guardian { get; set; }
[JsonIgnore]
public Patient Patient { get; set; }
[JsonProperty(PropertyName = "guardian_id")]
public int GuardianID
{
get { return Guardian.ID; }
set { Guardian.ID = value; }
}
[JsonProperty(PropertyName = "guardian_name")]
public string GuardianName
{
get { return Guardian.Name; }
set { Guardian.Name = value; }
}
[JsonProperty(PropertyName = "patient_id")]
public int PatientID
{
get { return Patient.ID; }
set { Patient.ID = value; }
}
[JsonProperty(PropertyName = "patient_name")]
public string PatientName
{
get { return Patient.Name; }
set { Patient.Name = value; }
}
}

反序列化代码

string json = @"[{'guardian_id':'1453','guardian_name':'Foo Bar','patient_id':'938','patient_name':'Foo Bar'}]";
var pairs = JsonConvert.DeserializeObject<Pair[]>(json);
if (pairs.Any())
{
var pair = pairs[0];
Console.WriteLine(pair.Guardian.Name);
Console.WriteLine(pair.Patient.Name);
}
