1.替换关键字,对字体变色。
public static string ReplaceRed(string strtitle, string redkey)
{
if (redkey == "" || redkey == null)
{
return strtitle;
}
else
strtitle = strtitle.Replace(redkey, " <font color='#ff0000'>" + redkey + " </font>");
return strtitle;
}
{
if (redkey == "" || redkey == null)
{
return strtitle;
}
else
strtitle = strtitle.Replace(redkey, " <font color='#ff0000'>" + redkey + " </font>");
return strtitle;
}
2.用正则,CSS背景变色。
protected string HighlightText(string inputText,string searchWord)
{
System.Text.RegularExpressions.Regex expression = new System.Text.RegularExpressions.Regex(searchWord.Replace(" ", "|"), System.Text.RegularExpressions.RegexOptions.IgnoreCase);
return expression.Replace(inputText,new System.Text.RegularExpressions.MatchEvaluator(ReplaceKeywords));
}
public string ReplaceKeywords(System.Text.RegularExpressions.Match m)
{
return "<span class='highlightTxtSearch'>" + m.Value + "</span>";
}
{
System.Text.RegularExpressions.Regex expression = new System.Text.RegularExpressions.Regex(searchWord.Replace(" ", "|"), System.Text.RegularExpressions.RegexOptions.IgnoreCase);
return expression.Replace(inputText,new System.Text.RegularExpressions.MatchEvaluator(ReplaceKeywords));
}
public string ReplaceKeywords(System.Text.RegularExpressions.Match m)
{
return "<span class='highlightTxtSearch'>" + m.Value + "</span>";
}
CSS:
.highlightTxtSearch
{
background-color:Yellow;
}
{
background-color:Yellow;
}
