Count JSON's Result

Question

Hi,

I have below json code and I want to know how can I get the count of the json's result, something like:

int total_found = data.Count;

Here is the code I am currently using:

var client = new HttpClient();

client.BaseAddress = new Uri("https://www.emiratesangels.org/api/generate_password_pin.php");

var content = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("email", TextEmail.Text.Trim()),
});

var response = await client.PostAsync("https://www.emiratesangels.org/api/generate_password_pin.php", content);

var result = await response.Content.ReadAsStringAsync();

PINData data = JsonSerializer.Deserialize<PINData>(result);

Thanks,
Jassim

Answer 1

If the API you are calling returns an array of items (assuming an array of PINData), you need to deserialize the string content into List<PINData>

List<PinData> data = JsonSerializer.Deserialize<List<PinData>>(result);
// Now data.Count will give you the count of items

Hi EmiratesAngels-2374,
What is "TextEmail" and "PINData" in your code?
Due to some uncertain objects in your code, I can't reproduce it.
So have you got correct json string(result) by using Content.ReadAsStringAsync?
If so, you can try the following code:

JObject jObj = (JObject)JsonConvert.DeserializeObject(JsonString);  
int count = jObj.Count；  

Here are also some similar threads you can refer to.
