将逗号分隔的字符串转换为json

Question

I have a comma seperated string value like

100,140

i need to convert that into a json string. that should be like

{"person":[{"id":"100"},{"id":"140"}]}

Please help me with a solution.

Answer 1

Considering you use a Json.net library , I suggest first to split your string to an array by comma andserialize it to a string:

var ids = "100,140".Split(',');
var personsString = JsonConvert.SerializeObject(new { person = ids.Select(x => new { id = x }).ToList()});

In my example, i serialize a dynamic type, but you can implement your custom class Person with ids array.

In MVC you have Json serialiser in conrollers. Just create model that describes your json in your case it will be:

    public class Model
    {
        public IEnumerable<Person> person { get; set; }
    }

    public class Person
    {
        public int id { get; set; }
    }

And then in your controller you are able to do this:

    public JsonResult GetData()
    {
        var str = "100,140"; // your string
        Model model = new Model();
        //parse string to model
        model.person = str.Split(',').Select(x => new Person { id = Convert.ToInt32(x) });
        //serialize to json
        return Json(model);
    }

first split your string and store in an array. Then convert your strings to jsonObjects. Add jsonobjects to jsonarray. follow the below code . it's working.

        string split = "100,140";
        string[] datas = split.Split(',');
        JsonArray jsonArry = new JsonArray();
        JsonObject jsonobj = new JsonObject();
        JsonObject jsonobj2 = new JsonObject();
        foreach (string data in datas)
        {
            jsonobj.SetNamedValue("id", JsonValue.CreateStringValue(data));
            jsonArry.Add(jsonobj);
        }
        jsonobj2.SetNamedValue("person", jsonArry);

also you can convert the jsonobject to string.

        string jsonString = jsonobj2.ToString();
