how to get all cache data which contains some keyword into it

Question

I'm working with cache in c# (Microsoft.Extensions.Caching.Memory) as i'm storing multiple data into cache like below.

IMemoryCache cache;

cache.Set("xxxx_1", "xxxx");
cache.Set("xxxx_2", "xxxx");
cache.Set("xxxx_3", "xxxx");

and can also get data one by one.

Getcachedata = (string)cache.Get("xxxx_1")

but i want to get the data complete data which contains Key like xxxx into it. i gone through many articles but didn't get help.

Your question is hard to understand - can you explain more, perhaps with some pseudo code what you want to achieve? what would your output look like? — sommmen, Jan 03 '20 at 09:27

@RajeshG with the solution mentioned i'm getting null key var keys = cache.Get>("abc.xyz"); but i can see key count with positive number — dev, Jan 03 '20 at 11:04

Try write CacheExtensions class to customize a GetCacheData method like below:

public static class CacheExtensions
{
    public static Dictionary<TKey,TValue> GetCacheData<TKey, TValue>(this IMemoryCache cache, TKey key)
    {
        var data = new Dictionary<TKey, TValue>();
        var value = (TValue)(cache.Get(key) ?? default(TValue));
        data.Add(key, value);
        return data;
    }
}

Then get the data result as shown:
