Brush.Dispose 方法

定义

释放 Brush 使用的所有资源。Releases all resources used by the Brush.

重载

Dispose()

释放由此 Brush 对象使用的所有资源。Releases all resources used by this Brush object.

Dispose(Boolean)

释放 Brush 使用的非托管资源,并选择性地释放托管资源。Releases the unmanaged resources used by the Brush and optionally releases the managed resources.

Dispose()

释放由此 Brush 对象使用的所有资源。Releases all resources used by this Brush object.

public:
 virtual void Dispose();
public void Dispose ();
abstract member Dispose : unit -> unit
override this.Dispose : unit -> unit
Public Sub Dispose ()

实现

注解

调用 Dispose 允许将此 Brush 对象使用的资源重新分配给其他目的。Calling Dispose allows the resources used by this Brush object to be reallocated for other purposes.

在完成使用 Dispose 后,应调用 BrushCall Dispose when you are finished using the Brush. Dispose 方法使 Brush 处于不可用状态。The Dispose method leaves the Brush in an unusable state. 调用 Dispose后,必须释放对 Brush 的所有引用,以便垃圾回收器可以回收 Brush 占用的内存。After calling Dispose, you must release all references to the Brush so the garbage collector can reclaim the memory that the Brush was occupying. 有关详细信息,请参阅清理非托管资源实现 Dispose 方法For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

备注

每次释放对 Dispose 的最后一个引用前,均应调用 BrushAlways call Dispose before you release your last reference to the Brush. 否则,在垃圾回收器调用 Brush 对象的 Finalize 方法之前,该对象正在使用的资源不会被释放。Otherwise, the resources it is using will not be freed until the garbage collector calls the Brush object's Finalize method.

Dispose(Boolean)

释放 Brush 使用的非托管资源,并选择性地释放托管资源。Releases the unmanaged resources used by the Brush and optionally releases the managed resources.

protected:
 virtual void Dispose(bool disposing);
protected virtual void Dispose (bool disposing);
abstract member Dispose : bool -> unit
override this.Dispose : bool -> unit
Protected Overridable Sub Dispose (disposing As Boolean)

参数

disposing
Boolean

若要释放托管资源和非托管资源,则为 true;若仅释放非托管资源,则为 falsetrue to release both managed and unmanaged resources; false to release only unmanaged resources.

注解

此方法由 public Dispose() 方法和 Finalize 方法调用。This method is called by the public Dispose() method and the Finalize method. Dispose() 调用受保护的 Dispose(Boolean) 方法,并将 disposing 参数设置为 trueDispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize 调用 disposing 设置为 falseDisposeFinalize invokes Dispose with disposing set to false.

如果 disposing 参数为 true,则此方法将释放此 Brush 引用的任何托管对象所持有的所有资源。When the disposing parameter is true, this method releases all resources held by any managed objects that this Brush references. 此方法调用每个引用对象的 Dispose() 方法。This method invokes the Dispose() method of each referenced object.

继承者说明

Dispose 可以由其他对象多次调用。 Dispose can be called multiple times by other objects. Dispose(Boolean) 重写时,请注意不要引用先前在调用 Dispose之前已释放的对象。When overriding Dispose(Boolean) be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. 有关如何实现 Dispose(Boolean)的详细信息,请参阅[实现 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). 有关 DisposeFinalize()的详细信息,请参阅[清理非托管资源](~/docs/standard/garbage-collection/unmanaged.md)和[重写 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)).
