检索微博此代码返回此错误消息：

类型的 “定义无参数的构造System.Collections.Generic.IEnumerable`1 [[Xxxx.Website.Templates.WidgetViews.Tweet， Dolphin，Version = 1.0.4801.24288，Culture = neutral， PublicKeyToken = null]]'。

我非常感谢您的帮助！

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; } 
    }

尝试使用列表，而不是

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