DbRawSqlQuery<TElement>::AllAsync Method
Asynchronously determines whether all the elements of the query satisfy a condition.
Assembly: EntityFramework (in EntityFramework.dll)
| Name | Description | |
|---|---|---|
![]() | 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. |
DbRawSqlQuery<TElement>::AllAsync Method (Func<TElement, Boolean>^)
Asynchronously determines whether all the elements of the query satisfy a condition.
Parameters
- predicate
-
Type:
System::Func<TElement, Boolean>^
A function to test each element for a condition.
Return Value
Type: System.Threading.Tasks::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.
| Exception | Condition |
|---|---|
| ArgumentNullException | predicate is null . |
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.
DbRawSqlQuery<TElement>::AllAsync Method (Func<TElement, Boolean>^, CancellationToken)
Asynchronously determines whether all the elements of the query satisfy a condition.
public: Task<bool>^ AllAsync( Func<TElement, bool>^ predicate, CancellationToken cancellationToken )
Parameters
- predicate
-
Type:
System::Func<TElement, Boolean>^
A function to test each element for a condition.
- cancellationToken
-
Type:
System.Threading::CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Return Value
Type: System.Threading.Tasks::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.
| Exception | Condition |
|---|---|
| ArgumentNullException | predicate is null . |
