扩展为<li>...</li>的方法表达 [英] Method that expands into <li>...</li> expression

问题描述

假设我在cshtml"文件中有以下内容:

Let's suppose I have the following in a 'cshtml' file:

<li class="nav-item">
    <a class="nav-link text-white" asp-area="" asp-controller="Home" asp-action="Index">Home</a>
</li>

<li class="nav-item">
    <a class="nav-link text-white" asp-area="" asp-controller="Home" asp-action="Privacy">Privacy</a>
</li>

我想设置一个方法 Link 以便我可以执行以下操作而不是上述操作:

I'd like to setup a method Link so that I can do the following instead of the above:

@Link("nav-link text-white", "Home", "Index", "Home")
@Link("nav-link text-white", "Home", "Privacy", "Privacy")

这是我尝试过的一种方法:

Here's one approach that I tried:

@{
    void Link(string a_class, string controller, string action, string text)
    {
        <li class="nav-item">
            <a class="@a_class" asp-area="" asp-controller="@controller" asp-action="@action">@text</a>
        </li>
    }

}

但是，这会导致以下错误消息:

However, this leads the following error message:

实现上述Link方法的好方法是什么?

What's a good way to implement the above Link method?

推荐答案

让我假设您想要实现可重用性.如果是这样，那么您将有一个更好的选择来为此创建局部视图

Let me assume you want to achieve reusablility. If thats the case then you will have a better option of creating a partial view for that

这将是您的部分视图

@model MyPartialModel
<li class="nav-item">
    <a class="@Model.Class" asp-area="@Model.Area" asp-controller="@Model.Controller" asp-action="@Model.Action">@Model.Text</a>
</li>

//Then you can call it anywhere
@await Html.PartialAsync("NameOfFile", new { Text ="whatever" Controller="MyController" Action=MyAction" className ="the-class"})
//Or even replace the anonymous object with a model rather

然后......就是这样

And.....that's it
