Create class parse from json to c#

问题

I've created a class to parse from json to C# with json.net library, but may be my class has something wrong.

My Json code:

Here is my class I've build:

public class abc{
         public data2[] data { get; set; }
         public paging2 paging { get; set; }

         public struct data2 {
             public string category { get; set; }
             public Array category_list { get; set; }
             public string name { get; set; }
             public string created_time { get; set; }
             public string id { get; set; }
         }
         public struct paging2 {
             public string next { get; set; }
         }
     }

I'm newbie in json and C# so I've some mistakes, please help me fix my class.

回答1:

Your classes should be:

public class CategoryList
{
    public string id { get; set; }
    public string name { get; set; }
}

public class Datum
{
    public string category { get; set; }
    public List<CategoryList> category_list { get; set; }
    public string name { get; set; }
    public string created_time { get; set; }
    public string id { get; set; }
}

public class Paging
{
    public string next { get; set; }
}

public class RootObject
{
    public List<Datum> data { get; set; }
    public Paging paging { get; set; }
}

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

Put your json to http://json2csharp.com/ and see yourself...

回答2:

Try this structure instead:

public class Paging
{
    public string Next { get; set; }
}

public class CategoryItem
{
    public string Name { get; set; }
    public string Id { get; set; }
}

public class Data
{
    public string Category { get; set; }
    public string Name { get; set; }
    public string Created_time { get; set; }
    public string Id { get; set; }
    public CategoryItem[] Category_list { get; set; }
}

public class Abc
{
    public Data[] Data { get; set; }
    public Paging Paging { get; set; }
}

Many people do not know, but Visual Studio does it himself. Copy the JSON (Ctrl + c), with the open .cs file, go to edit -> Paste Special -> Paste JSON Classes. PS: VS2012 + .net3.5 +
