In java for instance there's a way to use booleans as objects and not as
value types.
I would like to do the same in VB.NET so that I can check if the boolean has
been explicitely defined (is not Nothing).
But Boolean is a Structure in VB.NET (defined to False by default) and not
an Object so I'm afraid there's no way to do what I want without any
workaround.
Can you confirm that there's no object version of Boolean in VB.NET?
Thanks

Hi,
I'm in the process of upgrading an Object-Relational mapping library to .NET
2.0 and am wanting to implement support for Nullable typess.
I'm using Reflection to analyise the object that is being mapped and
building up a schema for the mapping.
This means I need a way to determine if the PropertyInfo.PropertyType is an
implementation of System.Nullable<>. I've been batting my head against this
for a while and only come up with one...

I am guessing there is a simple solution but given a type T, how can I check
for nullability?
how can I accomplish the following?
bool nullable = typeof(int).IsNullable; // false
bool nullable = typeof(int?).IsNullable; // true
bool nullable = typeof(string).IsNullable; // true
Thanks for any help.

i need to get an object of type Type when i have a string. That is the
easy part (Type.GetType("int")). What if i want that type to be
nullable? This doesn't work Type.GetType("int?"). It returns null.
This does work but i don't know how to know all that information at runtime.
Type.GetType("System.Nullable`1]")

My type contains constructor with nullable parameter like
public class Iandmed {
public Iandmed(DateTime? miskuup) {}
}
I tried to get its constructor parameter type name using
Type t = typeof(Iandmed);
ConstructorInfo c = t.GetConstructors();

I have a member variable of a class of type "int", and while assigning
value to it in a constructor, I want to check whether it is a null. I
am using following code:
if (NewMember.BPLNo == null)
NewMember.BPLNo = 0;
But, Visual Studio 2005 is giving warning that variables with type
'int' cannot be 'null'. How to check this?

I need to create method which returns my application object type as string :
TypeName(typeof( List<int>)) should return "List<int>" or
"System.Collections.Generic.List<int>"
TypeName(typeof( MyType<Customer>)) should return
"MyNamesp.MyType<MyBusiness.Customer>"
etc.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
