AllAsync<TSource>(IQueryable<TSource>, Expression<Func<TSource,Boolean>>, CancellationToken)

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

AllAsync<TSource>(IQueryable<TSource>, Expression<Func<TSource,Boolean>>)

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

public static System.Threading.Tasks.Task<bool> AllAsync<TSource> (this System.Linq.IQueryable<TSource> source, System.Linq.Expressions.Expression<Func<TSource,bool>> predicate);

<Extension()>
Public Function AllAsync(Of TSource) (source As IQueryable(Of TSource), predicate As Expression(Of Func(Of TSource, Boolean))) As Task(Of Boolean)

Type Parameters

TSource

The type of the elements of source.

Parameters

source
IQueryable<TSource>

An IQueryable<T> whose elements to test for a condition.

predicate
Expression<Func<TSource,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 source sequence passes the test in the specified predicate; otherwise, false.

Attributes
SuppressMessageAttribute

Exceptions

ArgumentNullException

source or predicate is null .

InvalidOperationException

source doesn't implement IDbAsyncQueryProvider .

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.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
IQueryable<TSource>

An IQueryable<T> whose elements to test for a condition.

predicate
Expression<Func<TSource,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 source sequence passes the test in the specified predicate; otherwise, false.
