) As IEnumerable(Of T)

	int index
)

[<ExtensionAttribute>]
static member Insert : 
        first : IEnumerable<'T> * 
        second : IEnumerable<'T> * 
        index : int -> IEnumerable<'T>

Parameters

first: Type: System.Collections.GenericIEnumerableT
The source sequence.
second: Type: System.Collections.GenericIEnumerableT
The sequence that will be inserted.
index: Type: SystemInt32
The zero-based index at which to insert elements from second.

Type Parameters

T: Type of the elements of the source sequence.

Return Value

Type: IEnumerableT
A sequence that contains the elements of first plus the elements of second inserted at the given index.

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).

Exceptions

Exception	Condition
ArgumentNullException	first is null.
ArgumentNullException	second is null.
ArgumentOutOfRangeException	Thrown if index is negative.
ArgumentOutOfRangeException	Thrown lazily if index is greater than the length of first. The validation occurs when yielding the next element after having iterated first entirely.
