DbRawSqlQuery<TElement>.AllAsync Method

Definition

Namespace:

System.Data.Entity.Infrastructure

Assembly:

EntityFramework.dll

Overloads

AllAsync(Func<TElement,Boolean>)	Asynchronously determines whether all the elements of the query satisfy a condition.
AllAsync(Func<TElement,Boolean>, CancellationToken)	Asynchronously determines whether all the elements of the query satisfy a condition.

AllAsync(Func<TElement,Boolean>)

Asynchronously determines whether all the elements of the query satisfy a condition.

public System.Threading.Tasks.Task<bool> AllAsync (Func<TElement,bool> predicate);

member this.AllAsync : Func<'Element, bool> -> System.Threading.Tasks.Task<bool>

Public Function AllAsync (predicate As Func(Of TElement, Boolean)) As Task(Of Boolean)

Parameters

predicate

Func<TElement,Boolean>

A function to test each element for a condition.

Returns

Task<Boolean>

A task that represents the asynchronous operation. The task result contains true if every element of the query result passes the test in the specified predicate; otherwise, false.

Exceptions

ArgumentNullException

predicate is null .

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.

AllAsync(Func<TElement,Boolean>, CancellationToken)

Asynchronously determines whether all the elements of the query satisfy a condition.

public System.Threading.Tasks.Task<bool> AllAsync (Func<TElement,bool> predicate, System.Threading.CancellationToken cancellationToken);

member this.AllAsync : Func<'Element, bool> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>

Parameters

predicate

Func<TElement,Boolean>

A function to test each element for a condition.

cancellationToken

CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

Task<Boolean>

A task that represents the asynchronous operation. The task result contains true if every element of the query result passes the test in the specified predicate; otherwise, false.

Exceptions

ArgumentNullException

predicate is null .

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.
