GetKeysAsync() Method
Gets the keys of the entities resulting from this query. Note that multiple calls to this method will always return the same set of keys.
- C#
- VB

Public MustOverride Function GetKeysAsync() As System.Collections.Generic.IAsyncEnumerable(Of iCore.Public.Types.IEntityKey)
Returns
System.Collections.Generic.IAsyncEnumerable<IEntityKey>
An enumerator that allows foreach to be used to process the keys in this collection.
GetKeysAsync(int) Method
Gets the keys of the entities resulting from this query, starting at the specified start index.
- C#
- VB
System.Collections.Generic.IAsyncEnumerable<iCore.Public.Types.IEntityKey> GetKeysAsync(int start);
Public MustOverride Function GetKeysAsync(ByVal start As Integer) As System.Collections.Generic.IAsyncEnumerable(Of iCore.Public.Types.IEntityKey)
Parameters
start int
The zero-based start index to start enumeration from.
Returns
System.Collections.Generic.IAsyncEnumerable<IEntityKey>
An enumerator that allows foreach to be used to process the keys in this collection.
Exceptions
IndexOutOfRangeException
start is negative or greater than the number of items in the result set.
Remarks
Note that multiple calls to this method will always return the same set of keys.
GetKeysAsync(int, int) Method

Parameters
start int
The zero-based start index to start enumeration from.
count int
The maximum number of items to retrieve.
Returns
System.Collections.Generic.IAsyncEnumerable<IEntityKey>
