c#
Hi,
I'm wondering what ?
means in C# ?
I'm seeing things like: DateTime?
or int?
. I suppose this is C# specific to C# 4.0?
I can't look for it in Google because I don't know the name of this thing.
The problem is I'm using DateTime and I have a lot of cast errors (from DateTime
to DateTime?
).
Thank you
