Question

I am using the ServiceStack Cache Client with Redis to cache integers.

I am calling the Get method on a key I know does not exist like this:

int? count;
count = cachClient.Get<int>(myKey);

count always has a value of 0 after this call.

From the documentation, I am expecting the Get method to return null for a non-existant key.

Am I doing something wrong or understanding this incorrectly?

You’ve said in the method call it needs to return type int, which isn’t nullable (and so returns it’s default value 0 instead). Try changing the second line to:

count = cachClient.Get<int?>(myKey); 

and see if it returns null then.
