How to retrieve a list of Memory Cache keys in .NET Core?

I found. I share it to help you.

var cacheEntriesCollectionDefinition = typeof(MemoryCache).GetProperty("EntriesCollection", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
        var cacheEntriesCollection = cacheEntriesCollectionDefinition.GetValue(_cache) as dynamic;
        List<ICacheEntry> cacheCollectionValues = new List<ICacheEntry>();

        foreach (var cacheItem in cacheEntriesCollection)
        {
            ICacheEntry cacheItemValue = cacheItem.GetType().GetProperty("Value").GetValue(cacheItem, null);
            cacheCollectionValues.Add(cacheItemValue);
        }
