Enumerable.Any(TSource) Method (IEnumerable(TSource), Func(TSource, Boolean))

Determines whether any element of a sequence satisfies a condition.

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

No code example is currently available or this language may not be supported.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
Type: System.Collections.Generic.IEnumerable(TSource)
An IEnumerable(T) whose elements to apply the predicate to.
predicate
Type: System.Func(TSource, Boolean)
A function to test each element for a condition.

Return Value

Type: System.Boolean
true if any elements in the source sequence pass the test in the specified predicate; otherwise, false.

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.

ExceptionCondition
ArgumentNullException

source or predicate is a null reference (Nothing in Visual Basic).

NoteNote:

This method does not return any one element of a collection. Instead, it determines whether any elements of a collection satisfy a condition.

The enumeration of source is stopped as soon as the result can be determined.

In Visual Basic query expression syntax, an Aggregate Into Any() clause translates to an invocation of Any.

The following code example demonstrates how to use Any to determine whether any element in a sequence satisfies a condition.
