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 Pattern
Lets 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
}
