@ Html.ActionLink一部作品和一个不 [英] @Html.ActionLink one works and one does not

问题描述

我有两个@ Html.ActionLink的一件作品，一个没有，我想不通为什么？

I have two @Html.ActionLink's one works and one does not and I cannot figure out why?

他们都是在同一个控制器内：StoreController和不同的控制器中同时调用ActionResults，这是一个工作，并呼吁处长类中的索引功能之一：

They are both within the same controller: StoreController and both call ActionResults within different controllers, this is the one that works and calls the Index function within the Director Class:

<ul>
@foreach (var item in Model)
{
    <li>
    <h2>@item.Title</h2>
    </li>
    <li class = "lihead">
    Directed by 
    @Html.ActionLink((string)item.Director.Name, "Index", "Director", new { searchString = item.Director.Name }, null)
    </li>
    <li>
    <i>@item.Synopsis</i>
    </li> 
    <li class = "lihead">
    Price per ticket £
    @item.Price
    </li>        
}

这是一个不工作之一：

 @foreach (var item in Model) {
        @Html.ActionLink("Check Availability", "CheckAvail", "Booking", new { id = item.ShowId })

}

这一个StoreController内时，我想它来调用BookingController内CheckAvail函数调用。然而，当我修改它如此确实工作：

This one calls within the StoreController when I want it to call the CheckAvail function within the BookingController. However it does work when I amend it as so:

 @foreach (var item in Model) {
        @Html.ActionLink("Check Availability", "CheckAvail", "Booking")}

但我需要它通过ShowId采取功能???

But I need it to take through the ShowId to the function???

推荐答案

使用像这样

@Html.ActionLink("Check Availability", "CheckAvail", "Booking", new { @id = item.ShowId },null)

据使用此重载

public static MvcHtmlString ActionLink(
    this HtmlHelper htmlHelper,
    string linkText,
    string actionName,
    string controllerName,
    Object routeValues,
    Object htmlAttributes
)

的最后一个参数是HTML属性。如果你有一些HTML属性附加伤害传递，你通过它的存在，而不是空

the last parameter is the HTML attribute. If you have some HTML atribute to pass, you pass it there instead of null

@Html.ActionLink("Check Availability", "CheckAvail", "Booking", new { @id = item.ShowId },new { @class="myCssClass"} )
