how to get the next autoincrement value in sql

Question

I am creating a winform application in c#.and using sql database.

I have one table, employee_master, which has columns like Id, name, address

Answer 1

When you delete a row from the table the next number will stay the same as it doesnt decrement in any way.

So if you have 100 rows and you deleted row 100. You would have 99 rows but the next number is still going to be 101.
