What is the best method of getting Int32 from first four bytes of GUID?

Question

I'm just wondering if it exists better solution for this.

BitConverter.ToInt32(sample_guid.ToByteArray(), 0)

Answer 1

I don't think there's a better solution than this.

Answer 2

I don't know if it's better, but it is easier to read:

Int32.Parse(sample_guid.ToString().SubString(0,1));

I'm a junior developer, admittedly, but the above reads easier to me than a byte conversion, and on a modern computer it would run indistinguishably quickly.

Answer 3

Dunno about a better solution, but I hope you don't intend to use that Int32 as a random (or unique) value.

You cannot depend on any sub part of a Guid to be unique. Guid is assumed to be unique, only in its entirety.
