因此需要以下函数做转换：

 
///<summary> 
///替换html中的特殊字符 
///</summary> 
///<paramname="theString">需要进行替换的文本。</param> 
///<returns>替换完的文本。</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> 
///恢复html中的特殊字符 
///</summary> 
///<paramname="theString">需要恢复的文本。</param> 
///<returns>恢复好的文本。</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; 
}
