因此需要以下函數做轉換： 

復制代碼代碼如下:

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

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