This article shows you how to use MemoryCache in ASP.NET Core 2.0. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

First you need to register the caching service in ConfigureServices

Public void ConfigureServices (IServiceCollection services) {services.AddMemoryCache (); services.AddMvc ();}

Get the IMemoryCache instance from the constructor of the Home controller in the following code

Public class HomeController: Controller {private IMemoryCache _ cache; public HomeController (IMemoryCache memoryCache) {_ cache = memoryCache;}}

The common use of cache is Set Get Remove. Some people like to encapsulate this code in a separate class library. I don't think it is necessary. It can be used directly in our Web project, and the extension method provided by IMemory is the best encapsulation.

Set cache Set

_ cache.Set ("key", "value")

Get cache Get

Var result = _ cache.GetOrCreate ("myKey", (entry) = > {entry.AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds; return DateTime.Now.ToString ();})

Remove cache Remove

_ cache.Remove ("key"); the above is how to use MemoryCache in ASP.NET Core 2.0. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
