If you know on the server side that the link is not available then just render a message that the action is not available:
如果您在服务器端知道该链接不可用，则只需呈现该操作不可用的消息：
@if(condition)
{
@Html.ActionLink("Delete", "Delete", new { id = @Model.Id})
}
else
{
<text>Action is not available</text>
}
Otherwise you can only disable a link with
否则，您只能禁用链接

Maybe you can create your own UI of type MvcHtmlString
也许您可以创建自己的 MvcHtmlString 类型的 UI
public static MvcHtmlString MyActionLink(this HtmlHelper helper, bool isClickable, string altText, RouteValueDictionary routeValues, object htmlAttributes = null)
{
// some logic with isClickale parameter here
if(isClickable == false)
{}
return new MvcHtmlString(helper.ToHtmlString());
}
and use it in your View
并在您的视图中使用它
@Html.MyActionLink( // some parameters here )
But I have never try it. Try find something about MvcHtmlStringon Google.
但我从来没有尝试过。尝试在 Google 上查找有关MvcHtmlString 的信息。

Someone might find this useful, I once solved a similar problem by turning @Html.ActionLink into an input <input type="submit" id = "submit" />and then you make it work as a link using javascript:
有人可能会发现这很有用，我曾经通过将 @Html.ActionLink 转换为输入来解决类似的问题<input type="submit" id = "submit" />，然后使用 javascript 使其作为链接工作：
<script>
$(document).ready(function () {
$('#submit').click(function () {
if(condition){
//sth (not working as a link)
}
else
{
window.location.href = "/home/thanks"; //working as a link
}
})
</script>
