auto generating a primary key in a c# app

[fguihen]

when a user wants to add a new patient to the database, i want to autogenerate a primary key to identify the patient. how do i autogenerate this in c#, so that i know it wont clash with any records already in the database?

In VB.NET, I would used the GUID... I don't know what the C# equivalent is but this is what it looks like in VB.NET:

 

Dim PKey as GUID

 

PKey = PKey.newguid()
