Guid.NewGuid() crea un nuevo guid aleatorio.

Hay dos maneras

var guid = Guid.NewGuid();

O 

var guid = Guid.NewGuid().ToString();

Ambos usan la clase Guid, el primero crea un objeto Guid, el segundo una cadena Guid.

var guid = new Guid();

Hey, es un Guid 'válido', aunque no muy útil.

(el guid es todo ceros, si no lo sabes. A veces esto es necesario para indicar que no hay guid, en los casos en los que no desea utilizar un Guid nullable)

To hace un guid "vacío" all-0 como 00000000-0000-0000-0000-000000000000.

var makeAllZeroGuID = new System.Guid();

O

var makeAllZeroGuID = System.Guid.Empty;

Para hacer un guid real con un valor único, lo que probablemente quieras. 

var uniqueGuID = System.Guid.NewGuid();

Si desea crear un Guid" deseado", puede hacer 

var tempGuid = Guid.Parse("<guidValue>");

Donde <guidValue> sería algo así como 1A3B944E-3632-467B-A53A-206305310BAE.

//Retrive your key ID on the bases of GUID 

declare @ID as uniqueidentifier

SET @ID=NEWID()
insert into Sector(Sector,CID)

Values ('Diry7',@ID)


select SECTORID from sector where CID=@ID
