The IDisposable pattern isn't one of the a classic patterns. It's a pattern suggested in
MSDN to implement the IDisposable interface. You should be familiar with the pattern
or with the interface because it's a basic thing to know about the .Net framework.
How to Use IDisposable PatternLets look at a code example.
public class DisposeObject : IDisposable
{
#region Members
private bool _disposed = false;
#endregion
#region IDisposable Members
~DisposeObject()
{
Dispose(false);
}
/// <summary>
/// Dispose the current object
/// </summary>
public void Dispose()
{
Dispose(true);
}
private void Dispose(bool disposing)
{
if (!_disposed)
{
if (disposing)
{
// clean up resources
CleanUp();
// The object will be cleaned up only if the method
// gets true - we are in the Dispose method.
// Therefore, you should call GC.SupressFinalize to
// take this object off the finalization queue
// and prevent finalization code for this object
// from executing a second time.
// Taken from MSDN.
GC.SuppressFinalize(this);
}
// dispose occurred
_disposed = true;
}
}
private void CleanUp()
{
// put here the code to dispose all managed
// and unmanaged resources
}
#endregion
}
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
