Returning JSON Data From API With RestSharp
Question
I am using RestSharp in my MVC project. I have these two classes to use as Models for the API Data.
public class ApiResponseON
{
public Data Data { get; set; }
}
public class Data
{
public string? comments { get; set; }
}
and I'm hitting the API to return data like this
public async Task<List<ApiResponseON>> GetJson(string on
{
RestRequest restRequest = new RestRequest($"/search?filter.on={on}&filter.status=All");
var data = await _restClient.GetAsync<List<ApiResponseON>>(restRequest);
return data;
}
but my issue is that I am getting this error on the return data; line
System.InvalidCastException: 'Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.'
What do I need to change in the code so this executes successfully?
