Removes an element from a Delphi set or removes an event handler in .NET applications.
procedure Exclude(var S: set of T; I: T);
Exclude(set of T S, T I);
System
When the first argument of Include is a set type variable, the Exclude procedure removes an element from the set. If S is a set type variable, and I is an expression of a type compatible with the base type of S. then Exclude(S,I) corresponds to S := S - [I] but the Exclude procedure generates more efficient code.
On the .NET platform, Exclude is overloaded. When the first argument of Exclude is a multicast event and the second argument is an event handler, Include removes the event handler from the event's listeners.
