SecurityState.EnsureState 方法
定义
在派生类中重写时,确保由 SecurityState 表示的状态在宿主上可用。When overridden in a derived class, ensures that the state that is represented by SecurityState is available on the host.
public:
abstract void EnsureState();
public abstract void EnsureState ();
abstract member EnsureState : unit -> unit
Public MustOverride Sub EnsureState ()
注解
此方法的实现应与下面的示例类似。The implementation of this method should be similar to the following example.
public override void EnsureState()
{
if (!IsStateAvailable())
throw new ApplicationException("WebcamSecurityState not available");
}
