class function Intersect<T>(const first: IEnumerable<T>; const second: IEnumerable<T>): IEnumerable<T>Type Parameters
- T
The type of the elements of the input sequences.
Parameters
- first
- IEnumerable<T>
A sequence whose distinct elements that also appear in second
will be returned.
- second
- IEnumerable<T>
A sequence whose distinct elements that also appear in first
will be returned.
Returns
A sequence that contains the elements that form the set intersection of two sequences.
Exceptions
first or second is nil .

class function Intersect<T>(const first: IEnumerable<T>; const second: IEnumerable<T>; const comparer: IEqualityComparer<T>): IEnumerable<T>Type Parameters
- T
The type of the elements of the input sequences.
Parameters
- first
- IEnumerable<T>
A sequence whose distinct elements that also appear in second
will be returned.
- second
- IEnumerable<T>
A sequence whose distinct elements that also appear in first
will be returned.
- comparer
- IEqualityComparer<T>
An equality comparer to compare values.
Returns
A sequence that contains the elements that form the set intersection of two sequences.
Exceptions
first or second is nil .
Remarks
If comparer is nil , the default equality comparer is
used to compare values.
