}Example usage
Use IMemcachedClient interface
public class HomeController : Controller
{
private readonly IMemcachedClient _memcachedClient;
private readonly IBlogPostService _blogPostService;
public HomeController(IMemcachedClient memcachedClient, IBlogPostService blogPostService)
{
_memcachedClient = memcachedClient;
_blogPostService = blogPostService;
}
public async Task<IActionResult> Index()
{
var cacheKey = "blogposts-recent";
var cacheSeconds = 600;
var posts = await _memcachedClient.GetValueOrCreateAsync(
cacheKey,
cacheSeconds,
async () => await _blogPostService.GetRecent(10));
return Ok(posts);
}
}Use IDistributedCache interface
public class CreativeService
{
private ICreativeRepository _creativeRepository;
private IDistributedCache _cache;
public CreativeService(
ICreativeRepository creativeRepository,
IDistributedCache cache)
{
_creativeRepository = creativeRepository;
_cache = cache;
}
public async Task<IList<CreativeDTO>> GetCreatives(string unitName)
{
var cacheKey = $"creatives_{unitName}";
IList<CreativeDTO> creatives = null;
var creativesJson = await _cache.GetStringAsync(cacheKey);
if (creativesJson == null)
{
creatives = await _creativeRepository.GetCreatives(unitName)
.ProjectTo<CreativeDTO>().ToListAsync();
var json = string.Empty;
if (creatives != null && creatives.Count() > 0)
{
json = JsonConvert.SerializeObject(creatives);
}
await _cache.SetStringAsync(
cacheKey,
json,
new DistributedCacheEntryOptions().SetSlidingExpiration(TimeSpan.FromMinutes(5)));
}
else
{
creatives = JsonConvert.DeserializeObject<List<CreativeDTO>>(creativesJson);
}
return creatives;
}
}
