Question

.NET Allows to create GUID in pre-determined format..

I want to create it with my custom format..

Is it possible?how?

Answer 1

There may be other ways, but what follows is a method I need to use a .NET Guid within PL/SQL editor (the bytes are in a different ordering):

  var bytes = guid.ToByteArray();
  var oraBytes =
    new[]
      {
        bytes[3], bytes[2], bytes[1], bytes[0],
        bytes[5], bytes[4],
        bytes[7], bytes[6],
        bytes[8], bytes[9], bytes[10], bytes[11], bytes[12], 
        bytes[13], bytes[14], bytes[15]
      };

  Guid g = new Guid(oraBytes);
  return g.ToString("N").ToUpperInvariant();

It may give you some inspiration in laying out the bytes as you need them.
