Enumerable.ElementAt(TSource) Method
Silverlight
Returns the element at a specified index in a sequence.
Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)
Type Parameters
- TSource
The type of the elements of source.
Parameters
- source
- Type: System.Collections.Generic.IEnumerable(TSource)
An IEnumerable(T) to return an element from.
- index
- Type: System.Int32
The zero-based index of the element to retrieve.
Return Value

Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(TSource). When you use instance method syntax to call this method, omit the first parameter.| Exception | Condition |
|---|---|
| ArgumentNullException | source is a null reference (Nothing in Visual Basic). |
| ArgumentOutOfRangeException | index is less than 0 or greater than or equal to the number of elements in source. |
If the type of source implements IList(T), that implementation is used to obtain the element at the specified index. Otherwise, this method obtains the specified element.
This method throws an exception if index is out of range. To instead return a default value when the specified index is out of range, use the ElementAtOrDefault(TSource) method.
