ASP.NET Core中如何获取最顶层缓存？

Question

I'm building a CMS. Every image would get a GUID. This means that even if user edit an image, it would be saved with a new GUID.

Thus I want to cache the image for the topmost possible cache. In fact I want to cache it forever.

ASP.NEt Core's Docs has a long list of options.

I'm not sure what option gives me the most caching time.

What should I do to cache my images forever?

Answer 1

you can use memoryCache Caching.Memory and set CacheItemPriority to NeverRemove

use the memoryCache in .NET Core

1. install Caching.Memory from nuget.

2. in your Startup.cs file, you need to introduce MemoryCache

    services.AddMemoryCache();

3. inject to Controler

   public class myContoroler: Controller { private readonly MemoryCache _memoryCache; public myContoroler(IMemoryCache memoryCache) { _memoryCache = memoryCache; } }
