Inverts the order of the elements in a sequence.
Assembly: System.Core (in System.Core.dll)
public static IEnumerable<TSource> Reverse<TSource>( this IEnumerable<TSource> source )
The type of the elements of source.
- Type: System.Collections.Generic.IEnumerable<>
A sequence of values to reverse.
Return ValueType: System.Collections.Generic.IEnumerable<>
A sequence whose elements correspond to those of the input sequence in reverse order.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<>. 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 is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C# or For Each in Visual Basic.
Unlike OrderBy, this sorting method does not consider the actual values themselves in determining the order. Rather, it just returns the elements in the reverse order from which they are produced by the underlying source.
The following code example demonstrates how to use to reverse the order of elements in an array.
