QueryableExtensions.AllAsync Method

Definition

Overloads

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

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

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.

[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures")]
public static System.Threading.Tasks.Task<bool> AllAsync<TSource> (this System.Linq.IQueryable<TSource> source, System.Linq.Expressions.Expression<Func<TSource,bool>> predicate);
static member AllAsync : System.Linq.IQueryable<'Source> * System.Linq.Expressions.Expression<Func<'Source, bool>> -> System.Threading.Tasks.Task<bool>
<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

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

Exceptions

source or 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.

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

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.

Exceptions

source or predicate is null .
