这是我的工作。可能有更好的方法。你可以试试。

注意:您的链接应该有 runat="server" 以便您可以从代码隐藏访问它们

protected void Page_Load(object sender, EventArgs e)
{            
    string curlink = Request.RawUrl;

    if (curlink.Contains("/administration/school")) 
    {
        schoolinfolink.Attributes["class"] = "selected";
    }
    else if (curlink.Contains("/administration/result"))
    {
        resultlink.Attributes["class"] = "selected";
    }
    else if (curlink.Contains("/administration/staff"))
    {
       staffslink.Attributes["class"] = "selected";
    }

}
