Answer 1

This is the best way to make the transparent background of winform.

right after this:

public partial class frmTransparentBackcolor : Form
{
    public frmTransparentBackcolor()
    {
        InitializeComponent();
        //set the backcolor and transparencykey on same color.
        this.BackColor = Color.LimeGreen;
        this.TransparencyKey = Color.LimeGreen;
    }
    protected override void OnPaintBackground(PaintEventArgs e)
    {
        e.Graphics.FillRectangle(Brushes.LimeGreen, e.ClipRectangle);
    }
}

hope this will help.
