Not quite a correct question. When you say "unique", you should specify: unique in what scope? Nothing is 100% universally unique in the word of finite state systems, and any computer is one of them.

Would a GUID[^] meet your needs? The object System.GUID has a static method, NewGuid, that lets you generate an identifier pretty much guaranteed to be unique.

Here is a article on generating Unique numbers in C#
Generate Unique Number in C#[^]

However if you looking to create unique values to insert into database i would recommend you to use Identity Property[^] in the SQL SERVER.
