- The source sequence.

- The predicate function.

IEnumerableT
A tuple of elements satisfying the predicate and those that do not,
respectively.
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
var (evens, odds) =
Enumerable.Range(0, 10).Partition(x => x % 2 == 0);
The
evens variable, when iterated over, will yield 0, 2, 4, 6
and then 8. The
odds variable, when iterated over, will yield
1, 3, 5, 7 and then 9.
