ServiceBase.CanStop Property

Gets or sets a value indicating whether the service can be stopped once it has started.

Namespace:  System.ServiceProcess
Assembly:  System.ServiceProcess (in System.ServiceProcess.dll)

'Declaration
Public Property CanStop As Boolean

Property Value

Type: System.Boolean
true if the service can be stopped and the OnStop method called; otherwise, false.

ExceptionCondition
InvalidOperationException

The service has already been started. The CanStop property cannot be changed once the service has started.

When Stop is called on a service, the Service Control Manager (SCM) verifies whether the service accepts Stop commands using the value of CanStop. For most services, the value of CanStop is true, but some operating system services, for example, do not allow the user to stop them.

If CanStop is true, the Stop command is passed to the service and the OnStop method is called if it is defined. If OnStop is not implemented in the derived class, the SCM handles the Stop command through the empty base class ServiceBase.OnStop method.
