When to use IDispose

[ssg31415926]

If I have a class which wraps a class which implements IDisposable,
should I implement IDisposable, too, in the wrapping class, and call
the wrapped class Dispose() from the wrapping class Dispose()?

E.g.

Public Class Widget : IDisposable
{
private DisposableObject disposableObject;

public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (disposing)
{
disposableObject.Dispose()
}
}
~Widget()
{
Dispose(false);
}

yes. if you read .net framework library documentation, the example in the
IDisposable.Dispose() method does same thing as yours. (example uses
private Component component; rather then DisposableObject. this is the only
difference with yours)

I think I must be having an off-day - I didn't spot the sample code in
there until your reply made me go and look again!

Thanks very much
