C#获取网页HTML源码实例

本文实例讲述了C#获取网页HTML源码的方法，分享给大家供大家参考。具体方法如下：

关键代码如下：

/// <summary>

/// 获取网页HTML源码

/// </summary>

/// <param name="url">链接 eg:http://www.baidu.com/ </param>

/// <param name="charset">编码 eg:Encoding.UTF8</param>

/// <returns>HTML源码</returns>

public static string GetHtmlSource(string url, Encoding charset)

{

    string _html = string.Empty;

    try

    {

 HttpWebRequest _request = (HttpWebRequest)WebRequest.Create(url);

 HttpWebResponse _response = (HttpWebResponse)_request.GetResponse();

 using (Stream _stream = _response.GetResponseStream())

 {

     using (StreamReader _reader = new StreamReader(_stream, charset))

     {

  _html = _reader.ReadToEnd();

     }

 }

    }

    catch (WebException ex)

    {

 using (StreamReader sr = new StreamReader(ex.Response.GetResponseStream()))

 {

     _html = sr.ReadToEnd();

 }

    }

    catch (Exception ex)

    {

 _html = ex.Message;

    }

    return _html;

}

测试代码如下：

public static void GetHtmlSourceTest()

{

    string _url = "http://www.baidu.com/";

    string _htmlSource = HttpWebRequestUtilsV2.GetHtmlSource(_url, Encoding.UTF8);

    Console.WriteLine(_htmlSource);

}

测试效果如下图所示：

希望本文所述对大家的C#程序设计有所帮助
