如何将下面的JSON转换为C#POCO对象

Question

[
{ "_id" : "BrownHair", "Count" : 1 },
{"_id" : "BlackHair" , "Count" : 5},
{"_id" : "WhiteHair" , "Count" : 15}
]

我想把上面的json转换成C#POCO对象，就像下面的一样

public class HairColors
{
public int BrownHair { get; set; }
public int BlackHair { get; set; }
public int WhiteHair { get; set; }       
}

请注意，我不能更改POCO和JSON的结构。

Answer 1

您可以使用JObject进行一些自定义解析https://dotnetfiddle.net/ydvZ3l

string json = "[rn  { "_id" : "BrownHair", "Count" : 1 },rn  {"_id" : "BlackHair" , "Count" : 5},rn  {"_id" : "WhiteHair" , "Count" : 15}rn]";
var jobjects = JArray.Parse(json);
foreach(var item in jobjects) {
// Map them here
Console.WriteLine(item["_id"]);
Console.WriteLine(item["Count"]);
}
// Output
//BrownHair
//1
//BlackHair
//5
//WhiteHair
15

Answer 2

我会使用这样的东西：

public class MyArray    {
public string _id { get; set; } 
public int Count { get; set; } 
}
public class Root    {
public List<MyArray> MyArray { get; set; } 
}

用途：

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
