显示来自控制器的图像的正确方法 [英] Correct way to show an image that comes from a controller

问题描述

我有一个加载图像文件的控制器:

I have a controller that loads an image file:

    //
    // GET: /MyController/Image/id
    public ActionResult Image(string id)
    {
        var dir = @"C:\Temp\Images";
        var path = Path.Combine(dir, id + ".png");
        return File(path, "image/png");
    }

在与动作MyController/Page/id分开的视图中，我匆忙哈希了一些html以显示图像:

In a separate view from action MyController/Page/id I have hastily hashed up some html to show the image:

<img src="../image/@Model.Name" />

然后还有一个链接:

<a href="../image/@Model.Name">
  <img src="../image/@Model.Name" />
</a>

它可以工作，但是我正在寻找一种使用@Html的更好的方法，因此对于以上两个方面，resharper可以帮助进行导航和验证.我已经尝试过了:

It works, but I am looking for a better way using @Html so resharper can help with navigation and validation, for the two above. I've tried this:

@Html.RenderAction("Image", "MyController", new { id = Model.Name })

但这不会编译，它表示为Expression must return a value to render.

But this doesn't compile, it says Expression must return a value to render.

推荐答案

我认为您只是在寻找Url.Action()，它将返回URL到Action:

I think you're just looking for Url.Action(), which returns an URL to an Action:

<img src="@Url.Action("Image", "ImageController", new { id = Model.ImageID })" />
