Parse JSON using httpclient.sendasync(request) via a foreach loop

Question

am using NewtonSoft to parse a JSON Api call.

The code must remain in the same format it is in.

My only problem is that I cannot iterate through the values of the JSON in a foreach loop.

How can I solve this problem?

public async Task callWebApi()
    {
        using (var httpClient = new HttpClient())
        {
            using (var request = new HttpRequestMessage(new HttpMethod("GET"), "https://www.metaweather.com/api/location/search/?lattlong=50.068,-5.316"))
            {
                var response = await httpClient.SendAsync(request);

                using (HttpContent content = response.Content)
                {


                    var jsonString = await response.Content.ReadAsStringAsync();
                    var data = JsonConvert.DeserializeObject<Object>(jsonString);
                Console.WriteLine("I need to parse distance, title, location_type, woeid,latt_long so that I can iterate through it using a foreach loop");
                Console.WriteLine(data);
                Console.Read();
                    // I don't know how to get the values of the json




                }
            }
        }

Here is a link to the working code:

you need to create a class that represents your json object in C# and then deserialized to that. You can use visual studio too for getting the json or you can use json2csharp.com for that.

The class for your json is:

C#

public class Location
{
    public int distance { get; set; }
    public string title { get; set; }
    public string location_type { get; set; }
    public int woeid { get; set; }
    public string latt_long { get; set; }
}

As you are receiving multiple objects i.e. an array you need to deserialize to an array of the above type.

C#

var data = JsonConvert.DeserializeObject<Location[]>(jsonString);

Now you can iterate on the array.

C#

foreach(var location in data)
{
  // your logic here
}

This is one of many common qestions asked on JSON Deserialization, so I have written an article to answer these questions: Working with JSON in C# & VB[^]
