如何将 JSON 数据存储到 IEnumerable 并循环遍历它？

Question

我想调用多个 API（使用不同的参数），然后将它们存储到某种容器中。然后我想抓住这个容器，发送到我的视图 (Razor)，遍历它并将它附加到我的 DOM（或显示它）。

以下无效。

public IActionResult Index()
{
    string[] day = {"Mon", "Tue", "Wed", "Thu", "Fri"};
    IEnumerable<API> results = new IEnumerable<API>();
    for (var i = 0; i < day.Length; i++)
    {
        var client = new RestClient("https://api.example.com/values/d=" + day[i]);
        var request = new RestRequest(Method.GET);
        request.AddHeader("cache-control", "no-cache");
        request.AddHeader("accept", "application/json; charset=utf-8");
        IRestResponse response = client.Execute(request);
        var responseContent = response.Content;

        results[i] = new JavaScriptSerializer().Deserialize<API>(responseContent);
    }

    return View(results);
}

Answer 1

这行不通，因为 IEnumerable 没有索引器：

results[i] =

或者您可以使用列表：

List<API> results = new List<API>();
for (var i = 0; i < day.Length; i++) //can also be foreach
{ 
   ///omitted 

   results.Add(new JavaScriptSerializer().Deserialize<API>(responseContent));
}

Answer 2

您可以 return IEnumerable 类型：

IEnumerable<API> results = new List<API>();


results.Add(new JavaScriptSerializer().Deserialize<API>(responseContent));

results ==> System.Collections.Generic.IEnumerable {System.Collections.Generic.List}
