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：

复制代码 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：

复制代码 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
