  Check GUID is null?

  Jul 24, 2019 02:17 PM|cenk1536|LINK

  Hi,

  I wonder if there is a way to check GUID is null. ReferenceId is GUID.

   var result= await _unitOfWork.GameBankRepository.GetGamesAsync(g =>
                          g.productCode == requestDto.productCode && g.referenceId == null);

  Thank you in advance.

  Hi,

  referenceId is a Guid or a Guid? (in C# the ? suffix is for nullable types)

  If it is "empty" rather than null, try g.referenceId == Guid.Empty

  (or if you have an error message tell what it is so that we don't have to guess first which problem you see).

  It is Guid. I will try Guid.Empty to check 00000000-0000-0000-0000-000000000000

  Thank you PatriceSc.
