使用RestSharp从API返回JSON数据

Question

我在我的MVC项目中使用RestSharp。我有这两个类作为Models用于API数据。

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

我点击API返回这样的数据

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，我得到这个错误在return data;行

系统。InvalidCastException: '无法转换类型的对象。"RestSharp。JsonArray'来键入system . string,‘System.Collections.Generic.IDictionary 2 [System.Object]"。">

我需要在代码中做什么修改才能使它成功执行?

注意这个模型是由众多JSON到c#转换器中的一个获得的，你可以在Visual Studio中完成，或者有免费的网站。

使用

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

一旦你有了你的结果，你可以按照你喜欢的方式修剪它，我把它留给你，这只是为了解决序列化错误。
