Overloads
| AnyAsync() |
Asynchronously determines whether the query contains any elements. |
| AnyAsync(Func<TElement,Boolean>) |
Asynchronously determines whether any element of the query satisfies a condition. |
| AnyAsync(CancellationToken) |
Asynchronously determines whether the query contains any elements. |
| AnyAsync(Func<TElement,Boolean>, CancellationToken) |
Asynchronously determines whether any element of the query satisfies a condition. |
AnyAsync()
Asynchronously determines whether the query contains any elements.
public System.Threading.Tasks.Task<bool> AnyAsync ();member this.AnyAsync : unit -> System.Threading.Tasks.Task<bool>Public Function AnyAsync () As Task(Of Boolean)Returns
A task that represents the asynchronous operation.
The task result contains true if the query result contains any elements; otherwise, false.
Remarks
Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
Applies to
AnyAsync(Func<TElement,Boolean>)
Asynchronously determines whether any element of the query satisfies a condition.
public System.Threading.Tasks.Task<bool> AnyAsync (Func<TElement,bool> predicate);member this.AnyAsync : Func<'Element, bool> -> System.Threading.Tasks.Task<bool>Public Function AnyAsync (predicate As Func(Of TElement, Boolean)) As Task(Of Boolean)Parameters
Returns
A task that represents the asynchronous operation.
The task result contains true if any elements in the query result pass the test in the specified predicate; otherwise, false.
Remarks
Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
Applies to
AnyAsync(CancellationToken)
Asynchronously determines whether the query contains any elements.
public System.Threading.Tasks.Task<bool> AnyAsync (System.Threading.CancellationToken cancellationToken);member this.AnyAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>Parameters
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation.
The task result contains true if the query result contains any elements; otherwise, false.
Remarks
Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
Applies to
AnyAsync(Func<TElement,Boolean>, CancellationToken)
Asynchronously determines whether any element of the query satisfies a condition.
public System.Threading.Tasks.Task<bool> AnyAsync (Func<TElement,bool> predicate, System.Threading.CancellationToken cancellationToken);member this.AnyAsync : Func<'Element, bool> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>Parameters
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation.
The task result contains true if any elements in the query result pass the test in the specified predicate; otherwise, false.
Remarks
Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
