CoreGraphics.CGContext.Dispose Method

Releases the resources used by the CGContext object.


protected virtual Void Dispose (Boolean disposing)


If set to true, the method is invoked directly and will dispose manage and unmanaged resources; If set to false the method is being called by the garbage collector finalizer and should only release unmanaged resources.


This Dispose method releases the resources used by the CGContext class.

This method is called by both the Dispose() method and the object finalizer (Finalize). When invoked by the Dispose method, the parameter disposing disposing is set to true and any managed object references that this object holds are also disposed or released; when invoked by the object finalizer, on the finalizer thread the value is set to false.

Calling the Dispose method when the application is finished using the CGContext ensures that all external resources used by this managed object are released as soon as possible. Once developers have invoked the Dispose method, the object is no longer useful and developers should no longer make any calls to it.
