static member ToArrayByIndex :
source : IEnumerable<'T> *
indexSelector : Func<'T, int> -> 'T[]
- source IEnumerableT
- The source sequence for the array.
- indexSelector FuncT, Int32
-
A function that maps an element to its index.
- T
-
The type of the element in source.
T
An array that contains the elements from the input sequence. The
size of the array will be as large as the highest index returned
by the
indexSelector plus 1.
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).
This method forces immediate query evaluation. It should not be
used on infinite sequences. If more than one element maps to the
same index then the latter element overwrites the former in the
resulting array.
