Queryable::Reverse<TSource> Method (IQueryable<TSource>^)

.NET Framework (current version)

Inverts the order of the elements in a sequence.

Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)

Syntax

public:
generic<typename TSource>
[ExtensionAttribute]
static IQueryable<TSource>^ Reverse(
	IQueryable<TSource>^ source
)

Parameters

source: Type: System.Linq::IQueryable<TSource>^
A sequence of values to reverse.

Return Value

Type: System.Linq::IQueryable<TSource>^

An IQueryable<T> whose elements correspond to those of the input sequence in reverse order.

Type Parameters

TSource: The type of the elements of source.

Exceptions

Exception	Condition
ArgumentNullException	source is null.

The Reverse<TSource>(IQueryable<TSource>^) method generates a MethodCallExpression that represents calling Reverse<TSource>(IQueryable<TSource>^) itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery<TElement>(Expression^) method of the IQueryProvider represented by the Provider property of the source parameter.

The query behavior that occurs as a result of executing an expression tree that represents calling Reverse<TSource>(IQueryable<TSource>^) depends on the implementation of the type of the source parameter. The expected behavior is that it reverses the order of the elements in source.

Examples

The following code example demonstrates how to use Reverse<TSource>(IQueryable<TSource>^) to reverse the order of elements in an array.
