這裏的想法是允許調用者爲循環的每個循環實現AfterHTMLPieceHandler
,我不知道它是不是正確的,或者它應該是一個事件或委託。老實說,我不知道區別,但這是另一個問題。如何向調用者實現公開事件,請參閱代碼示例?
//? Should it be static?
public static class PageScan
{
public delegate string AfterHTMLPieceHandler();
public static string GetHTML(string url)
{
HttpWebRequest wRequest = (HttpWebRequest)WebRequest.Create(url);
wRequest.Method = "GET";
HttpWebResponse wResponse = (HttpWebResponse)wRequest.GetResponse();
StreamReader sReader = new StreamReader(wResponse.GetResponseStream());
string html = sReader.ReadToEnd();
sReader.Close();
wResponse.Close();
sReader.Dispose();
return html;
}
public static void GetPiecesOfHtml(string html, string constantHtml)
{
while (html.IndexOf("http://portfoliopad.com/images/") > -1)
{
// it will retrieve a piece of html given the constantHtml and remove from html in order to break the loop in the end
//How Do I hit the event for each time one cycle of the loop ends?
}
}
}
真棒,感謝您的downvote沒有評論,你讓stackoverflow更豐富 – RollRoll 2013-03-23 23:25:06
你正在創建一個委託,但它不是指向任何事件,我可以看到..你看了起來如何做匿名代表或如何使用/創建代表..? – MethodMan 2013-03-23 23:54:49
