Asp.net C# 高亮匹配 Gridview label text from textbox multiple words

Question

當在文本框中輸入值時，應突出顯示與 GridView 的內容匹配的值。 我可以用一個單詞實現這一點，但是當我在文本框中使用多個單詞時，它就不起作用了。 任何幫助將非常感激。 下面是我后面的 C# 代碼：

 foreach (GridViewRow gvr in GridView1.Rows)                   //loop each row
     {
                    Label lblDescription = gvr.FindControl("lblDescription") as Label;                       
    
                    lblDescription.Text = Regex.Replace(lblDescription.Text, txtSearch.Text.Trim(), delegate (Match match)
                    {
                        return string.Format("<span style = 'background-color:#f30a31'>{0}</span>", match.Value);
                    }, RegexOptions.IgnoreCase);        
                   
    }

foreach (GridViewRow gvr in GridView1.Rows)                   //loop each row
     {                    
                Label lblDescription = gvr.FindControl("lblDescription") as Label;      
                string searchtext = txtSearch.Text;
                string[] searchtextList = searchtext.Split(' ');
                foreach (string textlist in searchtextList)
                {    
                    lblDescription.Text = Regex.Replace(lblDescription.Text, textlist.Trim(), delegate (Match match)
                    {
                        return string.Format("<span style = 'background-color:#ee953f'>{0}</span>", match.Value);
                    }, RegexOptions.IgnoreCase);
                }                    
    }
