You can use reflection to iterrate through methods, properties, etc. Using
this information, you could easily add these items as entries in a ListView
or a TreeView (then serialize it to XML, if so desired).

Here's a quick snippet that gets methods and properties from a TextBox
object, and adds them to a ListView (Be sure to include the System.Reflection
namespace):

private void button1_Click(object sender, System.EventArgs e)
{
    Type t = typeof(TextBox);
    //Get method info for an object
    MethodInfo[] mI = t.GetMethods();
    for (int x=0; x<mI.Length; x++)
    {   
        ListViewItem lvi = new ListViewItem();
        lvi.Text = mI[x].Name;
        this.listBox1.Items.Add(lvi);
    }
    //Get properties for an object
    PropertyInfo[] pI = t.GetProperties();
    for (int x=0; x<pI.Length; x++)
    {   
        ListViewItem lvi = new ListViewItem();
        lvi.Text = pI[x].Name;
        this.listBox1.Items.Add(lvi);
    }
}

Hope it helps.
