写了个批量查询qs的软件

因为需要,自己写了个批量查询qs的小软件。从网站中抓出需要的数据,格式化显示:

对字符串进行检测处理,先用Replace函数去掉字符串的空格,再用正则表达式匹配,返回匹配的字符串,如果没有匹配,则返回空字符串:

 //检测输入字符是否合法
        private string CheckText(string waitregexstr)
        {
            waitregexstr = waitregexstr.Replace(" ", "");
           string qsregex = "[qQ][sS][0-9]{12}";
           return  Regex.Match(waitregexstr,qsregex).Value;
        }

获取网页内容。这部分我还是不太会,拿了别人的代码。但它就是用用HttpWebRequest和HttpWebResponse的各个函数与stream来获取网页内容。

         #region GetWebContent 根据url返回网页编码
    
       
        HttpWebRequest httpReq;
        HttpWebResponse httpResp;

        string strBuff = "";
        char[] cbuffer = new char[256];
        int byteRead = 0;

        //string filename = @"c:log.txt";
        ///定义写入流操作 
        public string GetWebContent(string url)
        {
            url = url.Replace("
", "");
            Uri httpURL = new Uri(url);

            ///HttpWebRequest类继承于WebRequest,并没有自己的构造函数,需通过WebRequest的Creat方法 建立,并进行强制的类型转换 
            httpReq = (HttpWebRequest)WebRequest.Create(httpURL);
            ///通过HttpWebRequest的GetResponse()方法建立HttpWebResponse,强制类型转换

            httpResp = (HttpWebResponse)httpReq.GetResponse();
            ///GetResponseStream()方法获取HTTP响应的数据流,并尝试取得URL中所指定的网页内容

            ///若成功取得网页的内容,则以System.IO.Stream形式返回,若失败则产生ProtoclViolationException错 误。在此正确的做法应将以下的代码放到一个try块中处理。这里简单处理 
            Stream respStream = httpResp.GetResponseStream();

            ///返回的内容是Stream形式的,所以可以利用StreamReader类获取GetResponseStream的内容,并以

            //StreamReader类的Read方法依次读取网页源程序代码每一行的内容,直至行尾(读取的编码格式:UTF8) 
            StreamReader respStreamReader = new StreamReader(respStream, Encoding.UTF8);

            byteRead = respStreamReader.Read(cbuffer, 0, 256);
             
            while (byteRead != 0)
            {
                string strResp = new string(cbuffer, 0, byteRead);
                strBuff = strBuff + strResp;
                byteRead = respStreamReader.Read(cbuffer, 0, 256);
            }

            respStream.Close();
            return strBuff;
        }
        #endregion 

定义从网页内容中获取特定字符的函数。调用获取网页源码后,对字符串进行多次处理,首先用正则匹配regex.Match匹配到需要的字符串,再用Replace处理函数,得到自己所要显示的函数,这部分如果有大牛有更好的方案,请指教,感谢!

       private string operastr( string textboxtext)
        {
            try
            {
                string url = "避嫌,这里去掉了网址" + textboxtext.ToUpper() + ".htm";
                string webcontent = GetWebContent(url);
                string pattern = @"<h3>[sS]*?</table>";
                string butifulwoman = "";
                Regex regex = new Regex(pattern);
                if (regex.IsMatch(webcontent))
                {
                    int flag = 0;
                    string fatwoman = regex.Match(webcontent).Value;
                     butifulwoman = fatwoman.Replace("<td class="info-field"><div>", "
").Replace("</div></td>", "").Replace("<td class="info-value"><div style="">", ":").Replace("
", "").Replace("</tr>", "").Replace("<tr>", "").Replace("</tbody></table>", "").Replace("<table class="info-table"><tbody>", "").Replace("<h3>", "").Replace("</h3>", "").Replace(" ", "");

                }
                loadingGrid.IsOpen = false;
                return butifulwoman;
            }
            catch (Exception ex)
            {
                return "";
            }
        }

定义多行字符串的处理方法。根据TextBox的LineCount属性与getLinetext函数,对字符串进行处理

 //多行字符串的处理
        private void MutilpleStr(TextBox tb,Label lb)
        {
            int k = 0;
            string linestr="";
            for (int i = 0; i <tb.LineCount; i++)
            {
                linestr = CheckText(tb.GetLineText(i));
                if (linestr == "")
                {
                    wrong("qs格式错误!");
                    return;
                }
                else
                {

                    if (lb.Content==null)
                        lb.Content = operastr(tb.GetLineText(i));
                    else
                    {
                        lb.Content += "
------------------------------------";
                        lb.Content += "
" + operastr(tb.GetLineText(i));
                                                   
                    }
                }
            }
           
        }

  主体。根据用户输入的qs编号行数,分开一行与多行处理,

        if (mutipleText.Text == "")
            {
                wrong("文本框不能为空!");
               // mutipleText.Style =Style("mytextbox");
            }
            else if (this.mutipleText.LineCount>1)
            {
                loadingGrid.IsOpen = true;
                mutipleText.BorderBrush = Brushes.White;
                MutilpleStr(mutipleText,my);
                
            }
            else if(this.mutipleText.LineCount==1)
            {
                if (CheckText(mutipleText.Text).Length < 1)
                {
                    wrong("请输入正确的qs!");
                    return;
                }
                mutipleText.BorderBrush = Brushes.White;
               
                string text = mutipleText.Text.Replace(" ", "");
                string myneedstr = operastr(text);
                    my.Content = myneedstr;
            }
            

最新测试,抓取的数据太快会导致返回的qs全部是同一个,因为抓取的速度太快了,有空我改善下
