I have list of objects of following class:
public class Catagory
{
int catagoryId;
string catagoryNameHindi;
string catagoryNameEnglish;
List<Object> subCatagories;
public Catagory(int Id, string NameHindi, string NameEng,List<Object> l)
{
this.catagoryId = Id;
this.catagoryNameHindi = NameHindi;
this.catagoryNameEnglish = NameEng;
this.subCatagories = l;
}
}
public class SubCatagory
{
int subCatagoryId { get; set; }
string subCatNameHindi { get; set; }
string subCatNameEng { get; set; }
public SubCatagory(int Id, string NameHindi, string NameEng)
{
this.subCatagoryId = Id;
this.subCatNameEng = NameEng;
this.subCatNameHindi = NameHindi;
}
}
when I am converting this list to json string by using Newtonsoft.Json it returns array of empty objects.
string json=JsonConvert.SerializeObject(list);
I am getting following result.
[{},{},{},{},{}]
Please help me regarding this problem.
By default, NewtonSoft.Json will only serialize public members, so make your fields public:
public class Catagory
{
public int catagoryId;
public string catagoryNameHindi;
public string catagoryNameEnglish;
public List<Object> subCatagories;
public Catagory(int Id, string NameHindi, string NameEng, List<Object> l)
{
this.catagoryId = Id;
this.catagoryNameHindi = NameHindi;
this.catagoryNameEnglish = NameEng;
this.subCatagories = l;
}
}
If for some reason you really don't want to make your fields public, you can instead decorate them with the JsonPropertyAttribute to allow them to be serialized and deserialized:
[JsonProperty]
int catagoryId;
This attribute also allows specifying other options, such as specifying the property name to use when serializing/deserializing:
[JsonProperty("categoryId")]
int Category;
