如何使用webRequest仅获取页面内容?

问题描述：

嗨

在我的代码中，我将带有queryString参数的请求发送到我的网站，并毫无问题地得到结果.

in my code, i send a request to my webSite with queryString parameter(s) and get result without problem.

这是我的代码:

string strUrl = string.Format("http://myWebsite.com/Pages/CustomFormRaw.aspx?moduleGUID=df68c2b1-423d-4842-91c9-68c1c6233e11&insuranceID={0}", insuranceID);
WebClient client = new WebClient();
string downloadString = client.DownloadString(strUrl);

但是结果是我自己的结果(在我的示例0中)和页面内容的组合，就像这样:

but the result is composite of my own result (in my example 0) and page content, something like this :

0

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head><link rel="stylesheet" type="text/css" href="/DXR.axd?r=1_20-38coe" /><title>

</title><link href="../Modules/DrugStoreUpdater/Module.css" type="text/css" rel="stylesheet" /></head>
<body>
    <form method="post" action="./CustomFormRaw.aspx?moduleGUID=df68c2b1-423d-4842-91c9-68c1c6233e11&amp;insuranceID=1" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJODAyMzMxNDIxZGTJJx/x0n10RtBsW7+0dMqox9AimXUgVTmIzEZumJkYGQ==" />
</div>

....
....

我只想得到0而没有其他页面内容.有人可以帮助我吗?

嗨Hamed_1983，

Hi Hamed_1983,

谢谢您在这里发布.

对于您的问题，我建议使用正则表达式来在输出之前获取0，而不包含页面内容.

For your question, I suggest to use regex expression to get the 0 without page content before output.

请尝试以下代码.

  string str = "0< !DOCTYPE html >< html xmlns ";//str is the value of downloadstring.
            Regex rx = new Regex(@"^\d+");
            string a = rx.Match(str).ToString();// a is the 0 which you want to get without page content.

请尝试一下.我希望这会有所帮助.

Please have a try. I hope this would be helpful.

最好的问候，

温迪
