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
.
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.
