Html Helpers 可以在 Razor 页面之外使用吗

我有一个类“IncomeStatement”，用作 ViewModel。这个类有一个属性，可以生成一些相当复杂的 html，如下所示：

public MvcHtmlString HtmlPeriods { get; set; }
.... 
StringBuilder htmlPeriods = new StringBuilder(100);
htmlPeriods.AppendFormat(
"<td><a href='/Forecast/IndexPeriod?Period={1}'>{0}</a></td>",
    inc.NetSales, per.Period.PeriodID);
....
HtmlPeriods = MvcHtmlString.Create(htmlPeriods.ToString())

然后在 Razor 文件中，我使用 HtmlPeriods 属性，效果很好：

<th></th>@Model.HtmlPeriods<td></td>

但是，如果我想在我的类中使用 Html.ActionLink(...) 来创建，该怎么办？
很好的 Razorlike 链接，像这样的事情：

string forecastLink = 
Html.ActionLink("Edit Forecast", "/Forecast/IndexEdit?PeriodID=2005Q1");

我该怎么做？

I have a class 'IncomeStatement' that is used as a ViewModel. This class has a property that generates some fairly complicated html like this:

public MvcHtmlString HtmlPeriods { get; set; }
.... 
StringBuilder htmlPeriods = new StringBuilder(100);
htmlPeriods.AppendFormat(
"<td><a href='/Forecast/IndexPeriod?Period={1}'>{0}</a></td>",
    inc.NetSales, per.Period.PeriodID);
....
HtmlPeriods = MvcHtmlString.Create(htmlPeriods.ToString())

Then in the Razor file I use the HtmlPeriods property, which works fine:

<th></th>@Model.HtmlPeriods<td></td>

But what if I want to use the Html.ActionLink(...) in my class to create
nice Razorlike links,
something like this:

string forecastLink = 
Html.ActionLink("Edit Forecast", "/Forecast/IndexEdit?PeriodID=2005Q1");

How would I do that?

您可以使用 HtmlHelper 类来执行此操作。我想您会需要 GenerateLink 方法。

例子：

string link = HtmlHelper.GenerateLink(HttpContext.Current.Request.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Default", "Index", "Home", null, null);

You can use the HtmlHelper class to do this. I think you will want the GenerateLink method.

Example:

string link = HtmlHelper.GenerateLink(HttpContext.Current.Request.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Default", "Index", "Home", null, null);

在您的情况下，定义 HTML 帮助程序而不是在模型上使用属性和方法会更正确。例如：

using System.Web.Mvc;
using System.Web.Mvc.Html;

public static class HtmlExtensions
{
    public static MvcHtmlString HtmlPeriods(this HtmlHelper<SomeViewModel> html)
    {
        // here you can use html.ActionLink in order
        // to generate the desired markup

        // you also have access to the view model here:
        SomeViewModel model = html.ViewData.Model;

        ... 
    }
}

然后在你看来：

@Html.HtmlPeriods()

In your situation it would be more correct to define HTML helpers instead of using properties and methods on your models. For example:

using System.Web.Mvc;
using System.Web.Mvc.Html;

public static class HtmlExtensions
{
    public static MvcHtmlString HtmlPeriods(this HtmlHelper<SomeViewModel> html)
    {
        // here you can use html.ActionLink in order
        // to generate the desired markup

        // you also have access to the view model here:
        SomeViewModel model = html.ViewData.Model;

        ... 
    }
}

and then in your view:
