c# - Is it good idea to use uint instead of int as the primary key in data model class?

Question

We know that the primary keys are usually positive integers.

Is it good idea to use uint instead of int as the primary key in data model class?

Example:

public class Customer
{
   public uint CustomerId {get;set;}
   //others are omitted for the sake of simplicity.
}

Answer 1

The corresponding SQL data type is a signed number, so I'd stick with the int to avoid any surprises.
