如何从asp.net aspx页面当前页面的源代码 [英] how to get current page source from asp.net aspx page
问题描述
我尝试使用asp.net应用程序来获得当前页面的源代码。我发现了一张code的它转换HTML到PDF，但为了将我到PDF我需要获得页面的HTML code。我怎样才能得到这些作为一个字符串？我简单的code是这样的：
Hi, I am trying to get the current page source by using the asp.net application. I found a piece of code which converts html to pdf but in order to convert my page to pdf I need to get the html code of the page. How can I get these as a string? My simple code is like this:
string sPathToWritePdfTo = Server.MapPath("") + "/pdf_dosya_adi.pdf";
System.Text.StringBuilder sbHtml = new System.Text.StringBuilder();
sbHtml.Append("<html>");
sbHtml.Append("<body>");
sbHtml.Append("<font size='14'>HTML den PDF çevirme Test</font>");
sbHtml.Append("<br />");
sbHtml.Append("Body kısmında yazacak yazı");
sbHtml.Append("</body>");
sbHtml.Append("</html>");
using (System.IO.Stream stream = new System.IO.FileStream
(sPathToWritePdfTo, System.IO.FileMode.OpenOrCreate))
{
Pdfizer.HtmlToPdfConverter htmlToPdf = new Pdfizer.HtmlToPdfConverter();
htmlToPdf.Open(stream);
htmlToPdf.Run(sbHtml.ToString());
htmlToPdf.Close();
}
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "friendlypdfname.pdf"));
HttpContext.Current.Response.ContentType = "application/pdf";
HttpContext.Current.Response.WriteFile(sPathToWritePdfTo);
HttpContext.Current.Response.End();
如果我能得到的HTML code关闭我的asp.net页面，我把我的网页上的所有行成
sbHtml.Append（）;
通过使用一个for循环，这将解决我的问题，在我看来，code。
If I can get the html code off my asp.net page I put all line of my page into the sbHtml.Append(""); code by using a for loop and this will solve my problem in my opinion.
推荐答案
一种可能性是使用Web客户端发送一个HTTP请求到指定页面，并获得生成的HTML：
One possibility is to use a WebClient to send an HTTP request to the given page and get the resulting HTML:
using (var client = new WebClient())
{
string html = client.DownloadString("http://example.com/somepage.aspx");
}
这种方法的缺点是，它发送一个额外的HTTP请求。
The drawback of this approach is that it sends an additional HTTP request.
另一种可能性是直接渲染web窗体成字符串
Another possibility is to render the WebForm directly into a string:
using (var writer = new StringWriter())
{
Server.Execute("SomePage.aspx", writer);
string html = writer.GetStringBuilder().ToString();
}
