如何使用C＃解析JSON數組＃

Question

我需要使用C＃解析JSON數據，它是數組的集合。

ItemRelations: [ 
    { 
     rel: "System.Links.H-Forward", 
     source: {id: 123456,url: "https://somename.domain.com/DefaultCollection/_apis/wit/Items/123456"}, 
     target: {id: 231856,url: "https://somename.domain.com/DefaultCollection/_apis/wit/Items/231856"} 
    } 
] 

我可以分析簡單的JSON字符串，但是當涉及場景像上面我應該如何着手？

您可以使用Json2csharp爲您的json生成類。然後使用Json.Net從的NuGet：

void Main() 
{ 
    var json = @"{ItemRelations: [ 
    { 
     rel: ""System.Links.H-Forward"", 
     source: {id: 123456,url: ""https://somename.domain.com/DefaultCollection/_apis/wit/Items/123456""}, 
     target: {id: 231856,url: ""https://somename.domain.com/DefaultCollection/_apis/wit/Items/231856""} 
    } 
]}"; 

    var parsed = JsonConvert.DeserializeObject<RootObject>(json); 

    //Linqpad 
    //parsed.Dump(); 
} 

public class Source 
{ 
    public int id { get; set; } 
    public string url { get; set; } 
} 

public class Target 
{ 
    public int id { get; set; } 
    public string url { get; set; } 
} 

public class ItemRelation 
{ 
    public string rel { get; set; } 
    public Source source { get; set; } 
    public Target target { get; set; } 
} 

public class RootObject 
{ 
    public List<ItemRelation> ItemRelations { get; set; } 
}
