Question

I’m asking with my interest to learn:

Select * from Customer where CustomerId in(12,23,45);

Similarly is there any C#.Net Keyword for the same above?

Example: verify Date(month) not in Oct,Nov Dec. (not in SQL or LINQ)

I did it with Extension method( Ternary operator and || by verifying with month)
I’m looking for simple way to verify, if exists.

Threre is no keyword, however you can use the following construct:

using System.Linq;
...
(new [] {12, 23, 45}).Contains(customerID)
