自定义助手在Asp.net MVC3 [英] Custom Helper in Asp.net mvc3

问题描述

我有一个ASP.NET MVC3应用程序。我想有我想要显示在每一个表单自定义工具栏。这个定制工具栏可以有一个或多个动作links.So，我需要开发一个自定义的HTML帮助，我可以使用如下;

I have an ASP.NET MVC3 application. I would like to have a custom toolbar that I want to display in every form. This custom toolbar can have one or many action links.So, I need to develop a Custom Html helper that I can use like below;

@Html.CustomToolBar(items => {
          items.Add("Action","Controller","Name","Text");
          items.Add("Action1","Controller1","Name1","Text1");})

这个自定义扩展将产生HTML链接，我会显示它的窗体上。我有一个 ToolBarAction 类，我想获得列表＆LT; ToolBarAction＆GT; 从 @Html .CustomToolBar 。

This custom extension will produce the links html and I will display it on my form. I have a ToolBarAction class and I would like to get List<ToolBarAction> from @Html.CustomToolBar.

  public class ToolbarAction
  {
    public string Name { get; set; }
    public string Action { get; set; }
    public string Controller { get; set; }
    public string Text { get; set; }

  }

您可以告诉我怎么才能做到这一点？如果你可以点我相应的资源，那将是巨大真的..

Can you advise me how I can achieve this? If you could point me the appropriate resources, that would be great really..

非常感谢

问候..

推荐答案

像这样的东西（我不知道什么名称属性是，所以我加了它作为类）：

Something like this (I didn't know what the Name property was for, so I added it as the class):

public static class HelperExtensions
{
    public static MvcHtmlString Menu(this HtmlHelper html, Action<IList<ToolbarAction>> addActions)
    {
        var menuActions = new List<ToolbarAction>();
        addActions(menuActions);

        var htmlOutput = new StringBuilder();

        htmlOutput.AppendLine("<div id='menu'>");

        foreach (var action in menuActions)
            htmlOutput.AppendLine(html.ActionLink(action.Text, action.Action, action.Controller, new { @class = action.Name }).ToString());

        htmlOutput.AppendLine("</div>");

        return new MvcHtmlString(htmlOutput.ToString());
    }
}
