.NET Framework Class Library

Control..::.Dispose Method (Boolean)

Releases the unmanaged resources used by the Control and its child controls and optionally releases the managed resources.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Syntax

Visual Basic

Protected Overrides Sub Dispose ( _
    disposing As Boolean _
)

protected override void Dispose(
    bool disposing
)

Visual C++

protected:
virtual void Dispose(
    bool disposing
) override

abstract Dispose : 
        disposing:bool -> unit 
override Dispose : 
        disposing:bool -> unit

Parameters

disposing: Type: System..::.Boolean
true to release both managed and unmanaged resources; false to release only unmanaged resources.

Remarks

This method is called by the public Dispose() method and the Finalize method. Dispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize invokes Dispose with disposing set to false.

When the disposing parameter is true, this method releases all resources held by any managed objects that this Control references. This method invokes the Dispose() method of each referenced object.

Notes to Inheritors

Dispose can be called multiple times by other objects. When overriding Dispose(Boolean) be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. For more information about how to implement Dispose(Boolean), see Implementing a Dispose Method.

For more information about Dispose and Finalize, see Cleaning Up Unmanaged Resources and Overriding the Finalize Method.
