Dispose of objects in user control?

Question

I have a usercontrol that uses a DataSet objects. I would like to implement the IDisposable interface, however the usercontrol's designer class already has the following method:

    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

How can I correctly dispose of my DataSet object?

Answer 1

You can call that once the control is disposed. Just subscribe to the Disposed event of the control and dispose your own classes inside.

Answer 2

overriden Dispose method is not a part of Component Designer generated code

so you can modify it

protected override void Dispose(bool disposing)
{
    if (disposing)
    {
        if (components != null)
            components.Dispose();
        System.Diagnostics.Debug.WriteLine("Dispose DataSet Here");
    }
    base.Dispose(disposing);
}

Answer 3

Easiest way to safely handle disposing the Dataset object, is putting it in a using clause:

using (DataSet ds = new DataSet())
{
        // Put code that adds stuff to DataSet here.
        // ... The DataSet will be cleaned up outside the block.
}

This way you don't have to manually dispose the DataSet object afterwards. It will be disposed when leaving the using block.
