Sequential GUIDs

Question

I hope someone can answer this question.

How does the UuidCreateSequential method in the rpcrt4.dll class use to seed it\'s guids?

I know this much: Microsof

Answer 1

Rather than rely on the Win32 API, I typically use my own variant of a sequential guid which replaces eight bytes of the a standard guid with ticks from a datetime.

var guidBinary = new byte[16];
Array.Copy( Guid.NewGuid().ToByteArray(), 0, guidBinary, 0, 8 );
Array.Copy( BitConverter.GetBytes( DateTime.Now.Ticks ), 0, guidBinary, 8, 8 );
return new Guid( guidBinary );
