怎么获取HTMl源码

[jjyy17173]

我想做个小程序 读取自己网站上面的一些信息，先捕获所有源码 怎么捕获 哪位大哥告诉下 先谢过了

[syc958]

不知道你说的源码是指的html还是cs中的代码源码.....

[jjyy17173]

html 源码 谢谢 ·~~

[delphi_new]

这个不是很难，发送请求即可

[syc958]

StringBuilder sb = new StringBuilder();
Server.Execute("index.aspx", new StringWriter(sb));
File.WriteAllText(Server.MapPath("index.text"), sb.ToString());

// <summary>
/// 分析得到网页源代码

/// <param name="bm">网址编码</param>

public static string GetHtml(string url, string bm)
{
WebResponse response = null;
Stream stream = null;
StreamReader reader = null;

WebRequest request = WebRequest.Create(url);
response = request.GetResponse();
stream = response.GetResponseStream();


try
{
reader = new StreamReader(stream, System.Text.Encoding.GetEncoding(bm));
}
catch (Exception ex)
{
reader = new StreamReader(stream, System.Text.Encoding.GetEncoding("GB2312"));
}

string pagehtml = reader.ReadToEnd();


stream.Flush();
stream.Close();
response.Close();

return pagehtml;



}

今天没事，特地写了以下代码供LZ使用。

注意： 如果设置了代理服务器什么的，这样的方法是无法访问的。
