System.Text.RegularExpressions.Regex r =new System.Text.RegularExpressions.Regex(@"<http(.|\n)+jpg?>");
foreach(System.Text.RegularExpressions.Match m in r.Matches(s))
{
//this.Save(m.Value);
System.Console.WriteLine(m.Value);
}
为什么不匹配呢

using (StreamWriter sw = new StreamWriter("d:\\ouput.html"))//将获取的内容写入文本
{
sw.Write(m.Value);
}
} Console.WriteLine("下载成功"); //让控制台暂停,否则一闪而过了
} catch (WebException webEx)
{
Console.WriteLine(webEx.Message.ToString());
}
}
}
}
为什么调试成功却没有出现写入的文件????
