Guid HELP!!!!!!!!!! [Some what resolved]

[Magiaus]

for some eason in .net when check for guid != System.Guid.Empty it doesn't care if there is a value it is empty....? Same for the SqlTypes guid

I can check the values while I'm in debug mode but the .Empty/.Null test doesn't seem to work

if(key != System.Data.SqlTypes.SqlGuid.Null)

Okay.

guid != System.Guid.Empty works or seems to right now.
guid != System.Data.SqlTypes.SqlGuid.Null does not.

those are the same type of guid being tested btw.

so I am going to do guid.Value = System.Guid.Empty to see whats what

[Magiaus]

okay the .Empty doesn't work either

[Magiaus]

but if you covert the thing to a string and convert . null to a sting both will be "Null" so...... I'm comparing strings now

[Magiaus]

_key.ToString() != "Null"

seems to work

but for a normal guid it's != "00000-0000-.......) all zeros

[Magiaus]

in this project I create System.Guid from SqlGuid an SqlGuid from Guid. I have a dat layer with all SqlTypes and a Business layer with all System.Types

should I in my string check for "000000-0000-0000-0000" or whatever it is exactly?

[Magiaus]

exactly "00000000-0000-0000-0000-000000000000"
