如何通过asp.net中的actionlink发送数据? [英] How to send data through actionlink in asp.net?

问题描述

在我要制作的应用程序中，我的视图中有一个菜单，如下所示:

In the application that I am trying to make, I have a menu in my view as below:

<ul id="menu">
    <li>@Html.ActionLink("Create Project", "Display", "CreateDisplay")</li>
    <li>@Html.ActionLink("Open", "About", "Home")</li>
</ul>

其中CreateDisplay是控制器的名称，而Display是该控制器中将调用另一个视图的方法.

where CreateDisplay is the name of a controller and Display is a method in that controller which will call another view.

但是，我希望Display方法接受某些参数，例如此人的用户名.在当前视图中，我已获得用户名 @ViewData ["UserName"]

But, I want the Display method to accept certain parameters like username of the person. In the current view, I have obtained the username as @ViewData["UserName"]

但是我无法使用ActionLink传递这些值.我尝试将参数传递为

But I am not able to pass these values using ActionLink. I tried passing the parameters as

<li>@Html.ActionLink("Create Project", "Display?UserName="+@ViewData["UserName"], "CreateDisplay")</li>

但收到异常.

请提出一些方法.

非常感谢您.

推荐答案

您需要使用接受参数的重载作为路由值.在此处查看重载方法 ActionLink()

You need to use the overload that accepts parameters for route values. See the overloaded method ActionLink() here.

@Html.ActionLink(
    "Click me!",
    "Display",
    "CreateDisplay",
    new { UserName = "SetYourValHere" },
    null);
