哪里是在Html.Image .NET ASP MVC RC？ [英] Where is Html.Image in ASP .NET MVC RC?

问题描述

我无法找到新的MVC RC版Html.Image方法。请别人给我的例子如何使简单的图像在ASP .NET MVC RC站点。

I can't find the Html.Image method in new MVC RC version. Please somebody give me example how to render simple Image in ASP .NET MVC RC sites.

推荐答案

需要编写自己的或使用Url.Content（）方法来设置源属性。或者你可以使用我的。 ： - ）

Need to write your own or use the Url.Content() method to set the source attribute. Or you can use mine. :-)

public static class HtmlHelperExtensions
{

    public static string Image( this HtmlHelper helper, 
                                string url,
                                string altText,
                                object htmlAttributes )
    {
        TagBuilder builder = new TagBuilder( "img" );
        builder.Attributes.Add( "src", url );
        builder.Attributes.Add( "alt", altText );
        builder.MergeAttributes( new RouteValueDictionary( htmlAttributes ) );
        return builder.ToString( TagRenderMode.SelfClosing );
    }
}

用法：

<%= Html.Image( Url.Content( "~/Content/images/img.png" ),
               "alt text",
               new { id = "myImage", border = "0" } )
 %>

修改：自从我写了这个，我使用它消失。我将离开这里的答案，但为后人。虽然我觉得，还是从未来的装配方法，是一种合理的选择，我发现自己仅使用由一个UrlHelper提供的URL图像标记。当我重构我的助手到一个独立的库，这其中并没有获得晋级。我会重新评估，如果它使成（非期货）MVC库。

EDIT: Since I wrote this I've gone away from using it. I'll leave the answer here, though for posterity. While I think it, or the method from the Future assembly, is a reasonable choice, I find myself simply using the image tag with the url supplied by a UrlHelper. When I refactored my helpers into a standalone library, this one didn't make the cut. I'll re-evaluate if it makes it into the (non-futures) MVC library.

<img src="<%= Url.Content( "~/content/..." ) %>"
     alt="alt text"
     class="has-border" />
