您的模型

public class FishProduct
{
    public string fish_id { get; set; }
    public string fish_img { get; set; }
    public string fish_name { get; set; }
    public string fish_category { get; set; }
    public string size { get; set; }
    public string price { get; set; }
}

public class RootObject
{
    public List<FishProduct> fish_product { get; set; }
}

Web 服务调用和 JSON 反序列化

Webservice call and JSON Deserialisation

public async Task GetData()
{
 try
  {
  HttpClient client = new HttpClient();
  var result = await client.GetAsync("http://yourJSON_Url");
  result.EnsureSuccessStatusCode();
  string json = await result.Content.ReadAsStringAsync();
  List<FishProduct>  res= JsonConvert.DeserializeObject<List<FishProduct>>(json);

  }
 catch (Exception ex)
 {
   throw;
  }
}
