本文没有直接使用 StackExchange.Redis，而是使用 StackExchange.Redis.Extensions.Core 扩展。

安装步骤

创建 ASP.NET Core 应用程序 StackExchangeRedisDemo

安装如下 Nuget 包

• StackExchange.Redis.Extensions.Core
• StackExchange.Redis.Extensions.AspNetCore
• StackExchange.Redis.Extensions.Newtonsoft

appsettings.json 添加如下配置

  "Redis": {
    "Password": "123456",
    "AllowAdmin": true,
    "Ssl": false,
    "ConnectTimeout": 6000,
    "ConnectRetry": 2,
    "Database": 0,
    "Hosts": [
      {
        "Host": "127.0.0.1",
        "Port": "6379"
      }
    ]
  }

ConfigureServices 中注册 StackExchangeRedis 服务

public void ConfigureServices(IServiceCollection services)
{
    var redisConfiguration = Configuration.GetSection("Redis").Get<RedisConfiguration>();
    services.AddControllersWithViews();
    services.AddStackExchangeRedisExtensions<NewtonsoftSerializer>(redisConfiguration);
}

使用演示

在 Models 文件夹中添加 Product 类

namespace StackExchangeRedisDemo.Models
{
    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public double Price { get; set; }
    }
}

注入 IRedisCacheClient

public class DemoController : Controller
{
    private readonly IRedisCacheClient _redisCacheClient;
    public DemoController(IRedisCacheClient redisCacheClient)
    {
        _redisCacheClient = redisCacheClient;
    }
}

AddAsync 存储一个对象到 Redis

public async Task<IActionResult> Index()
{
    var product = new Product()
    {
        Id = 1,
        Name = "hand sanitizer",
        Price = 100
    };

    bool isAdded = await _redisCacheClient.Db0.AddAsync("Product", product, DateTimeOffset.Now.AddMinutes(10));

    return View();
}

使用 Redis Desktop Manager 查看

AddAllAsync 一次存储多个对象

public async Task<IActionResult> Index()
{
    var values = new List<Tuple<string, Product>>
    {
        new Tuple<string, Product>("Product1", new Product()
        {
            Id = 1,
            Name = "hand sanitizer 1",
            Price = 100
        }),
        new Tuple<string, Product>("Product2",new Product()
        {
            Id = 2,
            Name = "hand sanitizer 2",
            Price = 200
        }),
        new Tuple<string, Product>("Product3", new Product()
        {
            Id = 3,
            Name = "hand sanitizer 3",
            Price = 300
        })
    };

    await _redisCacheClient.Db0.AddAllAsync(values, DateTimeOffset.Now.AddMinutes(30));

    return View();
}

GetAsync 获取一个对象

public async Task<IActionResult> Index()
{
    var productdata = await _redisCacheClient.Db0.GetAsync<Product>("Product");
    return View();
}

GetAllAsync 一次获取多个对象

public async Task<IActionResult> Index()
{
    List<string> allKeys = new List<string>()
    {
        "Product1","Product2","Product3"
    };

    var listofProducts = await _redisCacheClient.Db0.GetAllAsync<Product>(allKeys);
    return View();
}

RemoveAsync 删除一个对象

public async Task<IActionResult> Index()
{
    bool isRemoved = await _redisCacheClient.Db0.RemoveAsync("Product");
    return View();
}

RemoveAllAsync 删除多个对象

public async Task<IActionResult> Index()
{
    List<string> allKeys = new List<string>()
    {
        "Product1",
        "Product2",
        "Product3"
    };

    await _redisCacheClient.Db0.RemoveAllAsync(allKeys);
    return View();
}

ExistsAsync 判断对象是否存在

public async Task<IActionResult> Index()
{
    bool isExists = await _redisCacheClient.Db0.ExistsAsync("Product");
    return View();
}

SearchKeysAsync 通配符搜索键

• "Product*" 搜索所有以 Product 开头的键
• "*Product*" 搜索所有包含 Product 的键
• "*Product" 搜索所有已 Product 结尾的键

public async Task<IActionResult> Index()
{
    var listofkeys1 = await _redisCacheClient.Db0.SearchKeysAsync("Product*");

    var listofkeys2 = await _redisCacheClient.Db0.SearchKeysAsync("*Product*");

    var listofkeys3 = await _redisCacheClient.Db0.SearchKeysAsync("*Product");
    return View();
}
