檢索微博此代碼返回此錯誤消息:與我在與解析一個Twitter流麻煩JSON

類型的 「定義無參數的構造System.Collections.Generic.IEnumerable`1 [[Xxxx.Website.Templates.WidgetViews.Tweet, Dolphin,Version = 1.0.4801.24288,Culture = neutral, PublicKeyToken = null]]'。

我非常感謝您的幫助!

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 class Metadata 
    { 
     public string result_type { get; set; } 
    } 


    public class Tweet 
    { 
     public Tweet() 
     {} 

     public string created_at { get; set; }

嘗試使用列表,而不是

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