How do I append a variable to a string in an Actio

问题:

I keep getting a Compilation Error and can't find matching overloaded method. I've tried a couple ways (variable, variable.toString). Below is the latest try.

When I click on the day (ex: 2) on the calendar the ActionLink should send the querystring: "Index?day=2".

@{ string dayAsString = startCount.ToString();}
<div><span>@Html.ActionLink(@startCount.ToString, "Index?day=" + dayAsString , "Event")</span></div>

回答1:

Do this

<div>
    <span>
        @Html.ActionLink(startCount.ToString(), "Index", new { day = startCount })
    </span>
</div>

The last parameter creates an anonymous object with the property day and value startCount. ActionLink knows to convert that into a querystring using the property name and the property value.

Edit:

If you want to target a specific controller, do this

@Html.ActionLink(startCount.ToString(), "Index", new { controller = "Event", day = startCount })

You can also do this

@Html.ActionLink(startCount.ToString(), "Index", "Event", new { day = startCount }, null)

but I don't like passing null as a parameter.

Here's a list of all the overloads: http://msdn.microsoft.com/en-us/library/dd505040.aspx

You can also just cycle in the intellisense.

This should work

@Html.ActionLink(@startCount.ToString,"Index","Yourcontroller",new { day=@startCount.ToString()} , null)

replace Yourcontroller with your controller name
