+# 使用 HybridCache 混合缓存库
+
+混合缓存可以同时使用内存缓存和分布式缓存，它可以提高缓存的命中率，减少对分布式缓存的访问，从而提高性能。
+
+- 当从缓存中获取数据时，它首先会从内存缓存中获取数据，如果内存缓存中没有数据，它会从分布式缓存中获取数据。
+- 当向缓存中写入数据时，它会同时向内存缓存和分布式缓存中写入数据。

+Service 1 ----> HybridCache ----> MemoryCache ----> DistributedCache

+```
+
+
+## 安装程序包
+
+```shell
+dotnet add package Microsoft.Extensions.Caching.Hybrid
+```
+
+## 配置服务
+
+```csharp
+builder.Services.AddHybridCache();
+```
+
+## 使用服务
+
+```csharp
+public class SomeService(HybridCache cache)
+{
+ private HybridCache _cache = cache;
+
+ public async Task GetSomeInfoAsync(string name, int id, CancellationToken token = default)
+ {
+ return await _cache.GetOrCreateAsync( $"{name}-{id}",async cancel => await GetDataFromTheSourceAsync(name, id, cancel),cancellationToken: token );
+ }
+
+ public async Task GetDataFromTheSourceAsync(string name, int id, CancellationToken token)
+ {
+ string someInfo = $"someinfo-{name}-{id}";
+ return someInfo;
+ }
+}
+```
+
+## 按标记移除缓存条目
+
+```csharp
+public class SomeService(HybridCache cache)
+{
+ private HybridCache _cache = cache;
+
+ public async Task GetSomeInfoAsync(string name, int id, CancellationToken token = default)
+ {
+ var tags = new List { "tag1", "tag2", "tag3" };

+ return await _cache.GetOrCreateAsync(

+ async cancel => await GetDataFromTheSourceAsync(name, id, cancel),
+ entryOptions,
+ tags,
