在ASP.Net中经常会从网面中取数据或更新网页的显示。因为HTML中有些特殊字符如<, >, &等，显示实际值不一致，造成保存到数据库再取出来时会不一样
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(">",">");
theString=theString.Replace("<","<");
theString=theString.Replace(" "," ");
theString=theString.Replace("\"",""");
theString = theString.Replace("\'", "'");
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(">",">");
theString=theString.Replace("<","<");
theString=theString.Replace(" "," ");
theString=theString.Replace(""","\"");
theString = theString.Replace("'", "\'");
theString=theString.Replace("<br/>","\n");
return theString;
}
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("\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(">",">");
theString=theString.Replace("<","<");
theString=theString.Replace(" "," ");
theString=theString.Replace(""","\"");
theString = theString.Replace("'", "\'");
theString=theString.Replace("<br/>","\n");
return theString;
}
