備註
公用方法和方法會呼叫這個方法 Dispose Finalize 。This method is called by the public Dispose method and the Finalize method. Dispose``Dispose(Boolean)使用設定為的參數叫用受保護的方法 disposing true 。Dispose invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize 以 Dispose 設定為的叫用 disposing false 。Finalize invokes Dispose with disposing set to false.
當 disposing 參數為 true 時，這個方法會釋放此參考之任何 managed 物件所持有的所有資源 ButtonBase 。When the disposing parameter is true, this method releases all resources held by any managed objects that this ButtonBase references. 這個方法會叫用每個參考物件的 Dispose 方法。This method invokes the Dispose method of each referenced object.
給繼承者的注意事項
Dispose 可以被其他物件呼叫多次。
Dispose can be called multiple times by other objects. 當覆寫時， Dispose(Boolean) 請小心不要參考先前在先前的呼叫中處置的物件 Dispose 。When overriding Dispose(Boolean) be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. 如需如何執行的詳細資訊 Dispose(Boolean) ，請參閱實 [處置方法](/dotnet/standard/garbage-collection/implementing-dispose)。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](/dotnet/standard/garbage-collection/implementing-dispose).
如需和的詳細資訊 Dispose Finalize() ，請參閱 清除非受控資源 和覆 寫 Finalize 方法。For more information about Dispose and Finalize(), see Cleaning Up Unmanaged Resources and Overriding the Finalize Method.
