如何在ActionLink中将变量附加到字符串? [英] How do I append a variable to a string in an ActionLink?

问题描述

我一直收到编译错误，找不到匹配的重载方法.我尝试了几种方法(variable，variable.toString).以下是最新的尝试.

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.

当我在日历上单击日期(例如2)时，ActionLink应该发送查询字符串:"Index?day = 2".

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>

推荐答案

执行此操作

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

最后一个参数创建一个具有属性day和值startCount的匿名对象. ActionLink知道可以使用属性名称和属性值将其转换为查询字符串.

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.

如果要定位特定的控制器，请执行此操作

If you want to target a specific controller, do this

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

您也可以这样做

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

但我不喜欢将null作为参数传递.

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

您也可以循环使用智能感知.

You can also just cycle in the intellisense.
