从字节数组ASP.NET MVC图像 [英] ASP.NET MVC image from byte array

问题描述

目前我有一个字节数组重新presenting我的形象在我的视图模型。我用下面的code显示它：

currently I have a byte array representing my Image in my ViewModel. I display it with the following code:

<img src="@String.Format("data:image/gif;base64,{0}", Convert.ToBase64String(Model.Image))" />

现在，我不希望有一个Base64字符串在我的源文件，而是一个图像的链接。这样的：

Now I don't want to have a Base64 String in my Source file, but rather a link to a image. Like:

<img src="Images/" + Model.Id"/>

这将返回一个图像。

which would return a Image.

我如何写这样的方法返回一个图像链接？

How do I write such a method to return a Image link?

推荐答案

您可以定义一个控制器动作，这将有助于该图像：

You could define a controller action that will serve the image:

public class ImagesController: Controller
{
    public ActionResult Index(int id)
    {
        byte[] imageData = ... go get your image data from the id
        return File(imageData, "image/png"); // Might need to adjust the content type based on your actual image type
    }
}

和在你看来只是 IMG 标签的的src 属性指向该控制器动作：

and in your view simply point the src property of the img tag to this controller action:

<img src="@Url.Action("Index", "Images", new { id = Model.Id })" />
