C#中HTML字符轉(zhuǎn)換函數(shù)分享

 更新時(shí)間：2012年07月27日 09:07:39   作者：  
在ASP.Net中經(jīng)常會(huì)從網(wǎng)面中取數(shù)據(jù)或更新網(wǎng)頁(yè)的顯示。因?yàn)镠TML中有些特殊字符如<, >, &等，顯示實(shí)際值不一致，造成保存到數(shù)據(jù)庫(kù)再取出來時(shí)會(huì)不一樣
因此需要以下函數(shù)做轉(zhuǎn)換：
復(fù)制代碼 代碼如下:

///<summary>
///替換html中的特殊字符
///</summary>
///<paramname="theString">需要進(jìn)行替換的文本。</param>
///<returns>替換完的文本。</returns>
public static string HtmlEncode(string theString)
{
theString=theString.Replace(">","&gt;");
theString=theString.Replace("<","&lt;");
theString=theString.Replace(" ","&nbsp;");
theString=theString.Replace("\"","&quot;");
theString = theString.Replace("\'", "&#39;");
theString=theString.Replace("\n","<br/>");
return theString;
}

///<summary>
///恢復(fù)html中的特殊字符
///</summary>
///<paramname="theString">需要恢復(fù)的文本。</param>
///<returns>恢復(fù)好的文本。</returns>
public static string HtmlDiscode(string theString)
{
theString=theString.Replace("&gt;",">");
theString=theString.Replace("&lt;","<");
theString=theString.Replace("&nbsp;"," ");
theString=theString.Replace("&quot;","\"");
theString = theString.Replace("&#39;", "\'");
theString=theString.Replace("<br/>","\n");
return theString;
}
