JSON Parse in C#

Question

What is wrong with this code?

JSON

cities: [
{
    city: {
        id: 1,
        name: "A.S.Peta",
        status: "Active"
    }
},..............

C# Code

public class Cities
{
    public City[] cities;    
}

public class City
{
    public int id; //{ get; set; }
    public string name; //{ get; set; }
    public string status; //{ get; set; }
}

//De-Serialization
var jsSerialize = new JavaScriptSerializer();
var cities = jsSerialize.Deserialize<Cities>(result);

Not populating internal object City. but showing collection with all records. Any Idea?

You can do one thing. Before preparing JSON object. You can check for a dummy JSON by serializing it on the server side and keeping a debugger. — Nisarg Shah

before Deserialize, did you try to serialize and see if the JSON string you are using is same as it generate, I think there is extra { } going in ... not sure though — Sumit Gupta

Simply try var jsSerialize = new JavaScriptSerializer(); var cities = jsSerialize.Serialize(new Cities()); and keep Debugger on the next statement — Nisarg Shah

Note there is a case difference between city, cities and City, Cities. — Moo-Juice

The "inner" city in your json object is adding a nested object within the array.

Try this json code :

{
    "cities": [
    {  
        "id": 1,
        "name": "A.S.Peta",
        "status": "Active"
    },
    {  
        "id": 2,
        "name": "Strasbourg",
        "status": "Active"
    }
    ]
}

If you need to stick to your originial json structure, you can try this c# code:

public class City2
{
    public int id { get; set; }
    public string name { get; set; }
    public string status { get; set; }
}

public class City
{
    public City2 city { get; set; }
}

public class RootObject
{
    public List<City> cities { get; set; }
}

This code has been automatically generated by this very useful web tool: json2C#

Invalid JSON primitive: cities.

Steve B Over a year ago

@RoyiNamir: you shoud wrap the whole jscon into a pair of brackets. I update my code to reflect this.

Royi Namir Over a year ago

HOwever please notice that { id: 1, name: "A.S.Peta", status: "Active" } is not a valid json. it's just that the JSS tolerate it.

@RoyiNamir: Why is that JSON object invalid?

Royi Namir Over a year ago

@stakx try it yourself jsonlint.com. each object key should come under ". i.sstatic.net/lzhFy.jpg
