more about nullable types where the Value property is used

[Tony Johansson]

Hello!

What purpose has this Value propery on nullable types because it possible
to display their value without using it.
For example:

int? intNullable1 = 3;
int? intNullable2 = 5;
Console.WriteLi ne(result); // This display 8
Console.WriteLi ne(result.Value ); // This also display 8 the same

So I can't see any point in using this Value property on nullable types or
have I missed something here perhaps
that makes the Value property useful to have?

try this:

public void Test(Int32 value)
{
}

Test(intNullabl e1);
Test(intNullabl e1.Value);

Re: more about nullable types where the Value property is used

The code:

Console.WriteLi ne(result);

Is calling the "ToString() " method on the "result" variable. So its
equivalent of you saying:

Console.WriteLi ne(result.ToStr ing());

Now, if you look at the internal implementation of the "ToString() " method
on the "Nullable" variable type (using Reflector) is implemented the
following way:

public override string ToString()
{
if (!this.HasValue )
{
return "";
}
return this.value.ToSt ring();
}

So as you can see, you were calling the "Value" property, you just didn't
know you were doing it.
