在request.servervariables（）中添加自定義標頭

Question

我必須在標頭中添加HTTP_MSDN，這樣每當我點擊按鈕時，此URL都應該顯示HTTP_MSDN。 請幫我。

protected void Page_Load(object sender, EventArgs e)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url");
    //HttpWebRequest req = WebRequest.Create("http://wap.mobiletashan.com") as HttpWebRequest;
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    request.Headers.Add("HTTP_MSDN", "0123456789");                      
}
protected void Button1_Click(object sender, EventArgs e)
{
    NameValueCollection coll;
    coll = Request.ServerVariables;
    String[] arr1 = coll.AllKeys;
    String[] arr2 = coll.GetValues(arr1[0]);
    Response.Write(Server.HtmlEncode(arr2[0]));
}

如果您需要添加標頭以進行請求，請在獲得響應之前添加標頭，如下所示：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url");
request.Headers.Add("HTTP_MSDN", "0123456789"); 
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
