用C#去除字符串中HTML的格式

 

 

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
            //删除样式
            Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"<STYLE>[/s/S]*<\/STYLE>", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            //删除WORD样式 begin

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

　　　　　　Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"Normal[^>]*?Mso", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"v[^>]*?}", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"o[^>]*?beha", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"w[^>]*?beha", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @".shape[^>]*?beha", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            //删除WORD样式 end
            //删除脚本
            Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"<script[^>]*?>.*?</script>", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);

            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, @"&(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 = Htmlstring.Replace("<", "");

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

            Htmlstring = Htmlstring.Replace("\r\n", "");
            #endregion

            //Htmlstring = Regex.Replace(Htmlstring, @"[^一-龥]", ""); //只留汉字
            return Htmlstring;

        }

调用时传入原数据．返回的就是除去后的．
