C# Language Creating a Guid


These are the most common ways to create an instance of Guid:

  • Creating an empty guid (00000000-0000-0000-0000-000000000000):
Guid g = Guid.Empty;
Guid g2 = new Guid();
  • Creating a new (pseudorandom) Guid:
Guid g = Guid.NewGuid();
  • Creating Guids with a specific value:
Guid g = new Guid("0b214de7-8958-4956-8eed-28f9ba2c47c6");
Guid g2 = new Guid("0b214de7895849568eed28f9ba2c47c6");
Guid g3 = Guid.Parse("0b214de7-8958-4956-8eed-28f9ba2c47c6");
