我想把从库里读出来的带有html的标签全部去除只留下文本该怎么作啊？

解决方案 »

  1.   

    string temp = Regex.Replace(sHtml, "<[^>]*>", "");
      

  2.   

    ///提取HTML代码中文字的C#函数 
    /// <summary>
    /// 去除HTML标记
    /// </summary>
    /// <param name="strHtml">包括HTML的源码 </param>
    /// <returns>已经去除后的文字</returns>
    using System;
    using System.Text.RegularExpressions;
    public class StripHTMLTest{
      public static void Main(){
        string s=StripHTML("<HTML><HEAD><TITLE>中国石龙信息平台</TITLE></HEAD><BODY>faddfs龙信息平台</BODY></HTML>");
        Console.WriteLine(s);
      }  public static string StripHTML(string strHtml){
        string [] aryReg ={
              @"<script[^>]*?>.*?</script>",          @"<(\/\s*)?!?((\w+:)?\w+)(\w+(\s*=?\s*(([""'])(\\[""'tbnr]|[^\7])*?\7|\w+)|.{0})|\s)*?(\/\s*)?>",

        string strOutput=strHtml;
        for(int i = 0;i<aryReg.Length;i++){
          Regex regex = new Regex(aryReg[i],RegexOptions.IgnoreCase);
          strOutput = regex.Replace(strOutput,aryRep[i]);
        }
        strOutput.Replace("<","");
