How can I combine these two similar methods into one?
<p>The methods below are just inverses of one another.  I suspect that I can combine the logic into one method.  I prefer to avoid Reflection.  Is it possible to combine them and maintain readability?</p>

<pre><code>    private void btnAdd_Click(object sender, EventArgs e)
    {
        LabEntity selectedItem = bindingSource1.Current as LabEntity;
        selectedLabsData.Add(selectedItem);
        availableLabsData.Remove(selectedItem);
    }

    private void btnRemove_Click(object sender, EventArgs e)
    {
        LabEntity selectedItem = bindingSource2.Current as LabEntity;//new binding source
        availableLabsData.Add(selectedItem);//called Add instead of remove
        selectedLabsData.Remove(selectedItem);//called Remove instead of Add
    }
</code></pre>
