访问的网页的内容用C＃ [英] Access the Contents of a Web Page with C#

问题描述

我想用C＃来访问一个网页的内容。例如，我想抓住谷歌的网页正文的文字。

I am trying to use C# to access the content of a webpage. For example, I want to grab the text of the body of google homepage.

我知道这是可行的在C＃中，其网络浏览器的控制。但我找不到这样做的一个很好的，简单的例子。所有的资源，我在网上找到涉及创建表格和图形用户界面，我不需要，我只需要一个良好的老控制台应用程序。

I know this is doable in C# with its web browser control. But I couldn't find a good, simple example of doing it. All the resources I found online involve creating Forms and GUI, which I don't need, I just need a good old Console Application.

如果任何人都可以提供实现上述简单的基于控制台的code段，这将是极大的AP preciated。

If anyone can provide a simple console-based code snippet that accomplishes the above, it'll be greatly appreciated.

推荐答案

其实web浏览器就是你要显示一个网页（嵌入在Windows应用程序管理Internet Explorer）的情况下使用的GUI控制。如果你只需要得到一个网页的内容，你可以使用的 Web客户端类：

Actually the WebBrowser is a GUI control used in case you want to visualize a web page (embed and manage Internet Explorer in your windows application). If you just need to get the contents of a web page you could use the WebClient class:

class Program
{
    static void Main(string[] args)
    {
        using (var client = new WebClient())
        {
            var contents = client.DownloadString("http://www.google.com");
            Console.WriteLine(contents);
        }
    }
}
