讓C＃談論Twitter。 （C＃新用戶的問題範圍。？）

Question

在試圖在http://www.voiceoftech.com/swhitley/?p=681落實Twitter的代碼，我得到一個編譯時錯誤：

The name 「apiResponse does not exist in the current context」,

通常我會被完全限定呼叫解決這種類型的問題，例如，而不是說：

Response.Redirect(oAuth.AuthorizationLinkGet()); 

我反而說：

System.Web.HttpContext.Current.Response.Redirect(oAuth.AuthorizationLinkGet()); 

的問題是，我不知道該怎麼做機智h apiResponse問題。有任何想法嗎？

下面是相關代碼文件：

using System.Configuration;

using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.WebControls;

using System.Collections.Specialized;  
namespace ArduinoSerialCommTest 
{ 
    class Tweet 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      string url = ""; 
      string xml = ""; 
      oAuthTwitter oAuth = new oAuthTwitter(); 

      if (System.Web.HttpContext.Current.Request["oauth_token"] == null) 
      { 
       //Redirect the user to Twitter for authorization. 
       //Using oauth_callback for local testing. 
       oAuth.CallBackUrl = "http://localhost"; 
       System.Web.HttpContext.Current.Response.Redirect(oAuth.AuthorizationLinkGet()); 
      } 
      else 
      { 
       //Get the access token and secret. 
       oAuth.AccessTokenGet(System.Web.HttpContext.Current.Request["oauth_token"], System.Web.HttpContext.Current.Request["oauth_verifier"]); 
       if (oAuth.TokenSecret.Length > 0) 
       { 
        //We now have the credentials, so make a call to the Twitter API. 
        url = "http://twitter.com/account/verify_credentials.xml"; 
        xml = oAuth.oAuthWebRequest(oAuthTwitter.Method.GET, url, String.Empty); 
        apiResponse.InnerHtml = System.Web.HttpContext.Current.Server.HtmlEncode(xml); 

        //POST Test 
        //url = "http://twitter.com/statuses/update.xml"; 
        //xml = oAuth.oAuthWebRequest(oAuthTwitter.Method.POST, url, "status=" + oAuth.UrlEncode("Hello @swhitley - Testing the .NET oAuth API")); 
        //apiResponse.InnerHtml = Server.HtmlEncode(xml); 
       } 
      } 
     } 
    } 
}

apiResponse處於aspx網頁服務器端股利。請再檢查一次。如果您沒有任何div，請在那裏輸入以下內容。

<div id="apiResponse" runat="server"> </div>
