使用 RestSharp 从 API 返回 JSON 数据

Question

我在我的 MVC 项目中使用 RestSharp。我有这两个类用作 API 数据的 Models。

public class ApiResponseON
{
    public Data Data { get; set; }
}

public class Data
{
    public string? comments { get; set; }
}

我正在按这样的 API 到 return 数据

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;
}

但我的问题是我在 return data; 行

上收到此错误

System.InvalidCastException: 'Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.'

我需要在代码中更改什么才能成功执行？

   public object NumberOut { get; set; }
   public object BindarySpecifications { get; set; }
   public object FlatSize { get; set; }
   public object ProductionPress { get; set; }
}

用法

var result = _restClient.GetAsync<Rootobject>(restRequest);

得到结果后，您可以随意修剪它，我会把它留给您，这只是为了解决序列化错误。
