I just ran across some code while working with System.DirectoryServices.AccountManagement
public DateTime? LastLogon { get; }
What is the ? after the DateTime for.
I found a reference for the ?? Operator (C# Reference), but it’s not the same thing. (280Z28: Here is the correct link for Using Nullable Types.)
The
?makes it a nullable type (it’s shorthand for theNullable<T>Structure and is applicable to all value types).Nullable Types (C#)
Note:
The
??you linked to is the null coalescing operator which is completely different.
