[<ExtensionAttribute>]
static member Partition :
source : IEnumerable<'T> *
predicate : Func<'T, bool> -> ValueTuple<IEnumerable<'T>, IEnumerable<'T>>
Parameters
- source
- Type: System.Collections.GenericIEnumerableT
The source sequence. - predicate
- Type: SystemFuncT, Boolean
The predicate function.
Type Parameters
- T
- Type of source elements.
Return Value
Type:
ValueTupleIEnumerableT,
IEnumerableT
A tuple of elements staisfying the predicate and those that do not,
respectively.
Usage Note
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).
Examples 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.
