Label.Dispose(Boolean) Label.Dispose(Boolean) Label.Dispose(Boolean) Label.Dispose(Boolean) Method

定義

釋放 Label 所使用的 Unmanaged 資源,並選擇性地釋放 Managed 資源。Releases the unmanaged resources used by the Label and optionally releases the managed resources.

protected:
 override void Dispose(bool disposing);
protected override void Dispose (bool disposing);
override this.Dispose : bool -> unit
Protected Overrides Sub Dispose (disposing As Boolean)

參數

disposing
Boolean Boolean Boolean Boolean

true 表示釋放 Managed 和 Unmanaged 資源,false 則表示只釋放 Unmanaged 資源。true to release both managed and unmanaged resources; false to release only unmanaged resources.

備註

這個方法是由公用Dispose方法Finalize和方法所呼叫。This method is called by the public Dispose method and the Finalize method. DisposeDispose(Boolean) 用受true保護的方法, 並將參數設定為。disposingDispose invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize使用設定disposingfalse的叫用。 DisposeFinalize invokes Dispose with disposing set to false.

當參數為 true 時,這個方法會釋放此Label參考之任何 managed 物件所持有的所有資源。 disposingWhen the disposing parameter is true, this method releases all resources held by any managed objects that this Label 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Dispose(Boolean)寫時, 請小心不要參考先前已在先前的Dispose呼叫中處置過的物件。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Dispose(Boolean)的詳細資訊, 請參閱[執行 Dispose 方法](~/docs/standard/garbage-collection/implementing-dispose.md)。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](~/docs/standard/garbage-collection/implementing-dispose.md). 如需DisposeFinalize()的詳細資訊,請參閱[清除非受控資源](~/docs/standard/garbage-collection/unmanaged.md)和覆[寫 Finalize 方法](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ddae83kx(v=vs.100))。For more information about Dispose and Finalize(), see [Cleaning Up Unmanaged Resources](~/docs/standard/garbage-collection/unmanaged.md) and [Overriding the Finalize Method](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ddae83kx(v=vs.100)).
