You need to use the Invoke method on a delegate to call it, e.g.
1
if predicate.Invoke(value) then ...
But you probably don't want to be using delegates at all in F#. Instead use function types:
1 2 3 4
member self.getAtomsByPredicate<'a>( ..., predicate : 'a -> bool ) =
...
if predicate value then
...Thanks a lot!
And you are right, I would normally not use a System.Predicate from F#, only in this case I am trying to implement an existing interface written in C#.

Hi
I am trying to implement a container in F#, but I am stuck because I cannot call a System.Predicate from my F# code:
member self.getAtomsByPredicate<'a>( ..., predicate : System.Predicate<'a> ) =
...
if predicate value then
...
And I keep getting the error: This value is not a function and cannot be applied. Anyone got any ideas?
