static member Exactly :
source : IEnumerable<'T> *
count : int -> bool
- source IEnumerableT
- The source sequence
- count Int32
- The exactly number of items a sequence must have for this
function to return true
- T
- Element type of sequence
Booleantrue if the number of elements in the sequence is equals
to the given integer or
false otherwise.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 numbers = new[] { 123, 456, 789 };
var result = numbers.Exactly(3);
The
result variable will contain
true.
