Description

Cannot compare a Guid to Guid.Empty

None of the following work for various reasons. some are compile errors, some generate System.NullReferenceException: Exception was thrown: System.NullReferenceException

_CurrentTripGUID == Guid.Empty
_CurrentTripGUID.Equals(Guid.Empty)
_CurrentTripGUID.Equals((object)Guid.Empty
_CurrentTripGUID.CompareTo((object)Guid.Empty) == 0

We desperately need a method to see if a Guid is == Guid.Empty

How to reproduce

Try any of these lines of code

private static Guid _CurrentTripGUID;

_CurrentTripGUID == Guid.Empty
_CurrentTripGUID.Equals(Guid.Empty)
_CurrentTripGUID.Equals((object)Guid.Empty
_CurrentTripGUID.CompareTo((object)Guid.Empty) == 0

Expected behaviour

I would expect all of these lines to function:

_CurrentTripGUID == Guid.Empty
_CurrentTripGUID.Equals(Guid.Empty)
_CurrentTripGUID.CompareTo(Guid.Empty) = 0

A workaround for now:
Convert both Guids to strings first and then compare the strings.

_CurrentTripGUID.ToString() == Guid.Empty.ToString()

But, if you need to compare 2 Guids and either one could be Empty ... it gets complicated.
Since "G1.CompareTo(G2)" will generate a "Null reference error" if either Guid is Empty, you must compare them both using the ToString() equivalent of each Guid to the string equivalent to Guid.Emtpy first !!

Comparing two Guids, G1 & G2

if ((G1.ToString() == Guid.Empty.ToString()) || (G2.ToString() = Guid.Empty.ToString()) || (G1.CompareTo(g2) != 0))
