怎么获取首尾固定的字符串

Question

在一段文本里出现/plus/download.php?open=2&id=114&uhash=67aed3395bb5d02c3eb3980e"
这一段字符串 开头/plus/download.php?open这段和最后一个引号是固定的 剩下的都是不固定的
我怎么才能取到以/plus/download.php?open开头以"结尾的字符串

Answer 1

string strRegex = @"/plus/download.php?[^\s]*";
            Regex r = new Regex(strRegex, RegexOptions.IgnoreCase);
            MatchCollection m = r.Matches(htmlCode);
开始的时候这么写能取到 后来取不到了直接取的就是/plus/download.php?[^\s]*这一段

Answer 2

注意?要转义
string pattern1 = @"(?i)/plus/download.php\?open[^""\s]+?""";

Answer 3

读取的还是(?i)/plus/download.php\?open[^"\s]+?"这个啊

Answer 4

string temp = "/plus/download.php?open=2&id=114&uhash=67aed3395bb5d02c3eb3980e\"";
            string pattern1 = @"(?i)/plus/download.php\?open[^""\s]+?""";
            temp = Regex.Match(temp, pattern1).Value;// /plus/download.php?open=2&id=114&uhash=67aed3395bb5d02c3eb3980e"有错么？还是你忘了加双引号

Answer 5

 private void button1_Click(object sender, EventArgs e)
        {
            HtmlCode.Text = GetHttp(Htmlstr.Text);
            string strRegex = @"(?i)/plus/download.php\?open[^""\s]+?""";
            Regex r = new Regex(strRegex, RegexOptions.IgnoreCase);
            MatchCollection m = r.Matches(HtmlCode.Text);
            Htmlstr.Text = strRegex;
        }
        private string GetHttp(string url)//获取网页源码
        {
            Uri uri = new Uri(url);
            HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(uri);
            myReq.UserAgent = "User-Agent:Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705";
            myReq.Accept = "*/*";
            myReq.KeepAlive = true;
            myReq.Headers.Add("Accept-Language", "zh-cn,en-us;q=0.5");
            HttpWebResponse result = (HttpWebResponse)myReq.GetResponse();
            Stream receviceStream = result.GetResponseStream();
            StreamReader readerOfStream = new StreamReader(receviceStream, System.Text.Encoding.GetEncoding("utf-8"));
            string strHTML = readerOfStream.ReadToEnd();
            readerOfStream.Close();
            receviceStream.Close();
            result.Close();
            return strHTML;
        }我的代码 你看看是不是哪里出错了

Answer 6

Htmlstr.Text = strRegex;
应该是
Htmlstr.Text = m[0].Value;
或者类似的……

Answer 7

      string str = "/plus/download.php?open=2&id=114&uhash=67aed3395bb5d02c3eb3980e\"";
        var s = Regex.Match(str, @"(?is)/plus/download\.php\?open[^""]+(?="")").Value;
        Response.Write(s);

结果
/plus/download.php?open=2&id=114&uhash=67aed3395bb5d02c3eb3980e
