System.Runtime.Caching.MemoryCache 与 HttpRuntime.Cache - 有什么区别吗? [英] System.Runtime.Caching.MemoryCache vs HttpRuntime.Cache - are there any differences?

问题描述

我想知道 MemoryCache 和 HttpRuntime.Cache 之间有什么区别，在 ASP.NET MVC 项目中首选哪一个?

据我所知，两者都是线程安全的，API乍一看或多或少相同，那么何时使用哪个有什么区别?

解决方案

I'm wondering if there are any differences between MemoryCache and HttpRuntime.Cache, which one is preferred in ASP.NET MVC projects?

As far as I understand, both are thread safe, API is from first sight more or less the same, so is there any difference when to use which?

解决方案

HttpRuntime.Cache gets the Cache for the current application.

The MemoryCache class is similar to the ASP.NET Cache class.

The MemoryCache class has many properties and methods for accessing the cache that will be familiar to you if you have used the ASP.NET Cache class.

The main difference between HttpRuntime.Cache and MemoryCache is that the latter has been changed to make it usable by .NET Framework applications that are not ASP.NET applications.
