c# - How to retrieve a list of Memory Cache keys in asp.net core?

Question

To be succinct. Is possible list all register keys from Memory Cache in the .Net Core Web Application?

I didn't find anything in IMemoryCache interface.

Answer 1

There is no such thing in .Net Core yet. Here is my workaround:

 var field = typeof(MemoryCache).GetProperty("EntriesCollection", BindingFlags.NonPublic | BindingFlags.Instance);
 var collection = field.GetValue(_memoryCache) as ICollection;
 var items = new List<string>();
 if (collection != null)
 foreach (var item in collection)
 {
      var methodInfo = item.GetType().GetProperty("Key");
      var val = methodInfo.GetValue(item);
      items.Add(val.ToString());
 }
