用asp.net实现 取页面中的所有链接
private void Page_Load(object sender, System.EventArgse)
{
//在此处放置用户代码以初始化页面
string url =http://www.gimoo.net;
System.Net.HttpWebRequesthttpReq;
System.Net.HttpWebResponsehttpRes;
System.UrihttpURL = new Uri(url);
httpReq =(System.Net.HttpWebRequest)System.Net.WebRequest.Create(httpURL);
httpReq.Method= "GET";
httpRes= (System.Net.HttpWebResponse)httpReq.GetResponse();
httpReq.KeepAlive= false;
System.IO.StreamReadersReader = newSystem.IO.StreamReader(httpRes.GetResponseStream(),System.Text.Encoding.GetEncoding("GB2312"));
stringres = sReader.ReadToEnd();
//以下是利用正则表达式对获取的文本流进行过滤
stringstrRegex = @"<a.+?a>";
System.Text.RegularExpressions.Regexr;
System.Text.RegularExpressions.MatchCollectionm;
r = newSystem.Text.RegularExpressions.Regex(strRegex,System.Text.RegularExpressions.RegexOptions.IgnoreCase);
m =r.Matches(res);
Response.Write("该页共有"+m.Count + " 个超连接<br/>");
for (inti = 0; i < m.Count; i++)
{
Response.Write(m[i].Value+ "<br/>");
}
}
{

用bat实现定时执行任务的批处理文件
@echooffsettxt1=%date:~0,4%::当前年settxt2=%date:~5,2%::当前月settxt3=%date:~8,2%::当前日settxt4=%time:~0,2%::当前小时settxt5=%time:~3,2%::当前分钟settxt6=%time:~6,2%::当前秒setdat
用bat实现的自动关机的代码
一般情况下我们都是使用shutdown来实现关机与重启用法:shutdown[/i|/l|/s|/r|/a|/p|/h|/e][/f][/m\computer][/txxx][/d[p:]xx:yy[/c"comment"]]没有参数显示帮助。这与键入/?
