推荐答案

您需要使用System.Net.HttpWebRequest使用"GET"方法来获取所需的HTTP资源.为此的编译时类型必须为System.Net.WebRequest，因为运行时类是由传递给其工厂方法Create的URI定义的.
请在此处查看代码示例: http://msdn.microsoft.com/zh-cn/library/system.net.webrequest.aspx [ ^ ].

从响应流中，您将读取包含所有HTML文件内容的字符串.然后，您需要解析HTML以提取META标签.例如，检查Majestic-12开源HTML解析器: http://www.majestic12.co.uk/projects/html_parser.php [^ ].

You need to get desired HTTP resource using System.Net.HttpWebRequest using "GET" method. A compile-time type for this must be System.Net.WebRequest as the run-time class is defined by the URI passed to its factory method Create.

See the code sample here: http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx[^].

From the response stream, you will read the string with all the HTML file content. Then you need to parse HTML to extract META tags. For example, check Majestic-12 Open Source HTML parser: http://www.majestic12.co.uk/projects/html_parser.php[^].

转到网站，右键单击查看源，在head标签中提供所有元信息.......:)

Go to the website, right click view source, in the head tag all meta information is given ....... :)
