How to implement the disposable pattern in a class that inherits from another disposable class?
- by TheRHCP
Hi,
I often used the disposable pattern in simple classes that referenced small amount of resources, but I never had to implement this pattern on a class that inherits from another disposable class and I am starting to be a bit confused in how to free the whole resources.
I start with a little sample code:
public class Tracer : IDisposable
{
bool disposed;
FileStream fileStream;
public Tracer()
{
//Some fileStream initialization
}
public void Dispose()
{
this.Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (!disposed)
{
if (disposing)
{
if (fileStream != null)
{
fileStream.Dispose();
}
}
disposed = true;
}
}
}
public class ServiceWrapper : Tracer
{
bool disposed;
ServiceHost serviceHost;
//Some properties
public ServiceWrapper ()
{
//Some serviceHost initialization
}
//protected override void Dispose(bool disposing)
//{
// if (!disposed)
// {
// if (disposing)
// {
// if (serviceHost != null)
// {
// serviceHost.Close();
// }
// }
// disposed = true;
// }
//}
}
My real question is: how to implement the disposable pattern inside my ServiceWrapper class to be sure that when I will dispose an instance of it, it will dispose resources in both inherited and base class?
Thanks.
