Supposing I have a class
Public Class Foo Property fooProp1 as Single Property fooProp2 as Single Property fooProp3 as Single End Class
to find the absolut maximum of a property (which contains positive or negative values) in a
Collection(Of Foo) I can do:
Collection.Max(Function(x As foo) Math.Abs(x.fooProp1))
and it returns the greater absolute value WITHOUT sign.
The question is how can I do to get the number WITH sign?
Thanks in advance. RG
Math.Abs will always return an unsigned value (the actual meaning of Absolute).
The get the value of a property you need only to READ it.
To get a MAX or MIN, you MUST compare values, like this:
dim x as integer = foo.property dim y as integer = last_foo_property (or anything else) Minimum = Math.Min(x,y) Maximum = Math.Max(x,y)
But, if are trying to get the lower and upper values of a collection, you may utilize:
MaxValue = Collection.Find(Collection, Function(Z) (Z > BiggerValue)) MinValue = Collection.Find(Collection, Function(Z) (Z < LowerValue))
where these values are gotten before the call.
Another way is to make a SORT and get the first and the last values...
