首页 / 网页编程 / ASP.NET / C#中HTML字符转换函数分享

因此需要以下函数做转换：
复制代码 代码如下:
///<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（">",">"）;
theString=theString.Replace（"<","<"）;
theString=theString.Replace（" "," "）;
theString=theString.Replace（""","""）;
theString = theString.Replace（""", "'"）;
theString=theString.Replace（" ","<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（">",">"）;
theString=theString.Replace（"<","<"）;
theString=theString.Replace（" "," "）;
theString=theString.Replace（""","""）;
theString = theString.Replace（"'", """）;
theString=theString.Replace（"<br/>"," "）;
return theString;
}
