ActionLink with multiple parameters
提问by Cameron
I want to create a URL like /?name=Macbeth&year=2011with my ActionLinkwhich I have tried doing like so:
我想创建一个像/?name=Macbeth&year=2011我ActionLink这样尝试过的 URL ：
<%= Html.ActionLink("View Details", "Details", "Performances", new { name = item.show }, new { year = item.year })%>
but it doesn't work. How do I do this?
但它不起作用。我该怎么做呢？
回答by Mikael ?stberg
The overload you are using makes the yearvalue end up in the html attributes of the link (check your rendered source).
您使用的重载使year值最终出现在链接的 html 属性中（检查您的渲染源）。
The overload signature looks like this:
重载签名如下所示：
MvcHtmlString HtmlHelper.ActionLink(
string linkText,
string actionName,
string controllerName,
object routeValues,
object htmlAttributes
)
You need to put both your route values in to the RouteValuesdictionary like this:
您需要将两个路由值都放入RouteValues字典中，如下所示：
Html.ActionLink(
"View Details",
"Details",
"Performances",
new { name = item.show, year = item.year },
null
)

In addition to Mikael ?stberg answer add something like this in your global.asax
除了 Mikael ?stberg 答案之外，在您的 global.asax 中添加类似的内容
routes.MapRoute(
"View Details",
"Performances/Details/{name}/{year}",
new {
controller ="Performances",
action="Details",
name=UrlParameter.Optional,
year=UrlParameter.Optional
});
then in your controller
然后在你的控制器中
// the name of the parameter must match the global.asax route
public action result Details(string name, int year)
{
return View();
}

Based on Mikael ?stberg answer and just in case people need to know how it does with html attr. Here is another example, reference from ActionLink
基于 Mikael ?stberg 的回答，以防万一人们需要知道它如何处理 html attr。这是另一个例子，参考来自ActionLink
@Html.ActionLink("View Details",
"Details",
"Performances",
new { name = item.show, year = item.year },
new {@class="ui-btn-right", data_icon="gear"})
@Html.ActionLink("View Details",
"Details",
"Performances", new RouteValueDictionary(new {id = 1}),new Dictionary<string, object> { { "class", "ui-btn-test" }, { "data-icon", "gear" } })
