ASP.NET Core 缓存 Caching 提供了包括但不限于以下几种存储方式:

内存缓存:https://xoyozo.net/Blog/Details/aspnetcore-memory-cache

SQL Server 缓存:https://xoyozo.net/Blog/Details/aspnetcore-sql-cache

Redis 缓存:https://xoyozo.net/Blog/Details/aspnetcore-redis-cache

MySQL 缓存:https://xoyozo.net/Blog/Details/aspnetcore-mysql-cache


Nuget 安装:Microsoft.Extensions.Caching.StackExchangeRedis

在 Startup.cs 文件的方法 ConfigureServices() 中添加:

services.AddStackExchangeRedisCache(options =>
{
    // 连接字符串
    options.Configuration = "192.168.111.134,password=aW1HAyupRKmiZn3Q";
    // 键名前缀
    options.InstanceName = "xoyozo_";
});

在控制器中注入 IDistributedCache:

public class TestController : Controller
{
    private readonly IDistributedCache cache;

    public TestController(IDistributedCache cache)
    {
        this.cache = cache;
    }

    public IActionResult Index()
    {
        string k = "count";
        int v = Convert.ToInt32(cache.GetString(k));
        v++;
        cache.SetString(k, v.ToString());
        return Content(v.ToString());
    }
}

结果:

更多用法详见官方文档:https://docs.microsoft.com/zh-cn/aspnet/core/performance/caching/distributed?view=aspnetcore-3.0


注:.NET 6 已不支持 Redis on Windows 3.0。
