You can access a Html item as a GenericHtmlControlby adding the runat='Server' attribute to the markup, you can then access the propertiesprogramatically as if it were a "normal" ASP.Net UI control.
您可以通过向标记添加 runat='Server' 属性来将Html 项作为GenericHtmlControl访问，然后您可以以编程方式访问属性，就好像它是“普通”ASP.Net UI 控件一样。
<li ID="hide" style="display: Block;" runat="Server"><a href="../list.aspx" >list Approval</a></li>
HtmlGenericControl listItem = this.hide as HtmlGenericControl;
if (listItem != null)
this.hide.style.Add("display", "none");

Add an idand runat="server"to your list item:
将id和添加runat="server"到您的列表项：
<li id="fooItem" runat="server">
<%-- ... --%>
</li>
Set the visibility property from code behind (C# example):
从后面的代码中设置可见性属性（C# 示例）：
if (someBool)
{
fooItem.Visible = false;
}
You can also use this approach for applying/removing a style:
您还可以使用这种方法来应用/删除样式：
if (someBool)
{
fooItem.Attributes.Add("class", "foobar");
// or removing a style
foobarItem.Attributes.Remove("class");
}
