C# create a new GUID

If you need a new GUID (not in code) and have MS Windows SDK installed, you can type this in the cmd prompt: uuidgen which will give you something like this: C:\>uuidgen ff9ddb07-bf8e-4f90-9475-8715c061231c If you need to do this at runtime in .Net, see System.Guid. System.Guid guid=System.Guid.NewGuid(); Console.WriteLine(guid.ToString);
