用C#去除字符串中HTML的格式

 

来源：http://www.cnzhai.com/blogview.asp?logID=431

想去掉除了段落标记之外的所有html标记，只要页面的文字，好比是我把代码贴到记事本里面的效果，去掉了链接等代码。 可以试试。

public static string DelHTML(string Htmlstring)//将HTML去除

         {      
             #region
             //删除脚本

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"<script[^>]*?>.*?</script>","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             //删除HTML

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"<(.[^>]*)>","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"([/r/n])[/s]+","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"-->","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"<!--.*","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            
             //Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"<A>.*</A>","");
        
             //Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"<[a-zA-Z]*=/.[a-zA-Z]*/?[a-zA-Z]+=/d&/w=%[a-zA-Z]*|[A-Z0-9]","");

                        

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(quot|#34);","/"",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(amp|#38);","&",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(lt|#60);","<",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(gt|#62);",">",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(nbsp|#160);"," ",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(iexcl|#161);","/xa1",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring,@"&(cent|#162);","/xa2",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(pound|#163);","/xa3",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring,@"&(copy|#169);","/xa9",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

             Htmlstring =System.Text.RegularExpressions. Regex.Replace(Htmlstring, @"&#(/d+);","",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

            
             Htmlstring.Replace("<","");

             Htmlstring.Replace(">","");

             Htmlstring.Replace("/r/n","");

             //Htmlstring=HttpContext.Current.Server.HtmlEncode(Htmlstring).Trim();
             #endregion


             return Htmlstring;

         }


调用时传入原数据．返回的就是除去后的．
