Get Length of array JSON.Net

Question

How can I get the length of a JSON Array I get using json.net in C#? After sending a SOAP call I get a JSON string as answer, I use json.net to parse it.

Example of

Answer 1

You can use below line to get the length of JSON Array in .Net (JArray) .

 int length = ((JArray)test["jsonObject"]).Count;

Answer 2

Just try this:

var test= ((Newtonsoft.Json.Linq.JArray)json).Count;

Answer 3

You can cast the object to a JArray and then use the Count property, like so:

JArray items = (JArray)test["JSONObject"];
int length = items.Count;

You can then loop the items as follows:

for (int i = 0; i < items.Count; i++)
{
    var item = (JObject)items[i];
    //do something with item
}

According to Onno (OP), you can also use the following:

int length = test["JSONObject"].Count();

However, I have not personally confirmed that this will work

Answer 4

The easiest and cleanest way I found:

int length = test["JSONObject"].Count;

Answer 5

This worked for me supposing the json data is in a json file. In this case, .Length works but no intellisence is available:

    public ActionResult Index()
    {
        string jsonFilePath = "C:\\folder\\jsonLength.json";
        var configFile = System.IO.File.ReadAllText(jsonFilePath);

        JavaScriptSerializer jss = new JavaScriptSerializer();
        var d = jss.Deserialize<dynamic>(configFile);

        var jsonObject = d["JSONObject"];
        int jsonObjectLength = jsonObject.Length;
        return View(jsonObjectLength);
    }
