从Byte [] Asp.Net MVC 3加载Image Src [英] Load Image Src from Byte[] Asp.Net MVC 3

问题描述

我有一个ASP.net MVC 3应用程序，我想在模型中将图像存储为字节，然后将其从模型加载到html图像标记的src属性中。

I have an ASP.net MVC 3 application where I want to store an image as bytes in the model and then load it from the model into the src attribute of an html image tag.

例如

//Property in Model
 public byte[] Image { get; set; }

但是当我尝试这个时它会出错：

But when I try this it errors:

<img src = "@Model.Image" alt=""/>

如何从字节加载图像？我想避免再次调用Controller将图像作为FileResult。

How can I load the image from bytes? I want to avoid calling the Controller again to get the image as a FileResult.

是否可以？

推荐答案

最简单的方法是这样的：

The easiest way is something like this:

<img src="data:image/png;base64,@System.Convert.ToBase64String(Model.Image)" alt=""/>

这假设是PNG有效负载，并且不受传统浏览器的很好支持。

This assumes a PNG payload and is not very well supported by legacy browsers.

我实际上建议将其保存到磁盘并让你的网络服务器单独托管它。

I would actually recommend saving it to disk and letting your web server host it up separately.
