我在解析 twitter 流时遇到问题，此代码返回此错误消息：

没有为“System.Collections.Generic.IEnumerable`1[[Xxxx.Website.Templates.WidgetViews.Tweet, Dolphin, Version=1.0.4801.24288, Culture=neutral, PublicKeyToken=null]]”类型定义无参数构造函数。

非常感谢您的帮助！

public partial class TwitterWidgetView
{
  protected override void OnLoad(System.EventArgs e)
  {
    string listName = "sas";
    string twitterListPath = "https://search.twitter.com/search.json?q=" + listName;
    WebClient wc = new WebClient();
    var json = wc.DownloadString(twitterListPath);
    JavaScriptSerializer ser = new JavaScriptSerializer();
    var tweetList = ser.Deserialize<IEnumerable<Tweet>>(json);
  }
}

    {
        public string result_type { get; set; }
    }


    public class Tweet 
    {
        public Tweet()
        {}

尝试改用列表

var tweetList = ser.Deserialize<List<Tweet>>(json);
