            };

 Questions.AddRange(new List<Question> { q1, q2 });
 

 public class Question
    {
        public string QuestionTitle { get; set; } = string.Empty;

        public string Answer { get; set; } = string.Empty;
    }

Hello,

Firstly, based on your Json data, you need to create a Question class like following code.

public class Question
    {

    public int No { get; set; }

    public string QuestionTitle { get; set; }

    public string Opt1 { get; set; }

    public string Opt2 { get; set; }

    public string Opt3 { get; set; }

    public string Opt4 { get; set; }

    public string Answer { get; set; }
}

Then you can use HttpClient to request Json data from your api. After requesting was successful, we can get the Json data, we can convert Json Data to Object by Newtonsoft.Json nuget packages, you need to install it in NuGet package manage before you used it.

  async Task<List<Question>> GetApiData()
   {
       string apiUrl = "https://sheet2api.com/v1/wlS0h0USxm9p/quiz"; 
       List<Question> Questions = new List<Question>();
       using (HttpClient client = new HttpClient())
       {
           try
           {
               // Make a GET request to the API
               HttpResponseMessage response = await client.GetAsync(apiUrl);

              // Check if the request was successful (status code 200)
               if (response.IsSuccessStatusCode)
               {
                   // Read the content of the response
                   string jsonString = await response.Content.ReadAsStringAsync();


                  // Deserialize the JSON string into an object
                   Questions = JsonConvert.DeserializeObject<List<Question>>(jsonString);
                   
                   // Now you can work with the 'apiData' object
                   Console.WriteLine("Received data:");
                  
               }
               else
               {
                   Console.WriteLine($"Error: {response.StatusCode} - {response.ReasonPhrase}");
               }
           }
           catch (Exception ex)
           {
               Console.WriteLine($"Error: {ex.Message}");
           }
       }
      return Questions;
   }

In the end, you can get the List<Question> by invoking following code.

 List<Question> res= await GetApiData();
