用程序怎么实现抓取别人网页上的数据呢？
见标题，如果有源程序或者教程可以发我邮箱：512187557@qq.com谢谢大家了！ --------------------编程问答-------------------- 1.利用HttpWebRequest 或者 WebClient 得到网页源码
2.DOM分析或者正则匹配数据
2.输出 --------------------编程问答--------------------

Response.Write(arr);
}
/// <summary>
/// HTTP GET方式请求数据.

/// <param name="url">URL.</param>
/// <returns></returns>
public string HttpGet(string url)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = "GET";
//request.ContentType = "application/x-www-form-urlencoded";
request.Accept = "*/*";
request.Timeout = 15000;
request.AllowAutoRedirect = false;
WebResponse response = null;
string responseStr = null;
try
{
response = request.GetResponse();
if (response != null)
{
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
responseStr = reader.ReadToEnd();
reader.Close();
}
}
catch (Exception)
{
throw;
}
finally
{
request = null;
response = null;
}
return responseStr;
}
谢谢，我现在正在用myeclpise打开，不知道，这个是软件呢，还是源代码呢？ --------------------编程问答--------------------
亲，我看不懂喔。 --------------------编程问答--------------------
哈哈哈，太深奥了。我果然丢东西丢的太多了！！
补充：.NET技术 , C#
