Gets whether cancellation has been requested for this CancellationTokenSource.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsCancellationRequested As Boolean
public bool IsCancellationRequested { get; }

Property Value

Type: System.Boolean
Whether cancellation has been requested for this CancellationTokenSource.

Remarks

This property indicates whether cancellation has been requested for this token source, such as due to a call to its Cancel method.

If this property returns true, it only guarantees that cancellation has been requested. It does not guarantee that every handler registered with the corresponding token has finished executing, nor that cancellation requests have finished propagating to all registered handlers. Additional synchronization may be required, particularly in situations where related objects are being canceled concurrently.
