Is there a simpler way to do this if statement in C#

Question

I have the following:

if (model.PartitionKey.Substring(2, 2) == \"05\" || 
    model.PartitionKey.Substring(2, 2) == \"06\")

I have more like t

Answer 1

if (new []{"05", "06"}.Contains(model.PartitionKey.Substring(2, 2))

the syntax might be far off, corrections are welcome :)

Edit: new []
