Allow 2 decimal points / dots in textbox using c#

I am developing a windows application using c#.

The user enters a website name which should allow only 2 dots for eg www.google.com

I have written but that is accepting only 1 dot. The code I have written is :-

if ((e.KeyChar == '.') && ((sender as TextBox).Text.IndexOf('.') > -1))
{
e.Handled = true;
}

Thanks in Advance ...!!!

 e.Handled = true;
}

Hi Dear,

private void txtPrice_KeyPress(object sender, KeyPressEventArgs e)
{
// To disallow typing in the beginning writing
if (txtPrice.Text.Length == 0)
{
if (e.KeyChar == '.')
{
e.Handled = true;
}
}
if (!char.IsDigit(e.KeyChar) && e.KeyChar != 8 && e.KeyChar != 46)
{
e.Handled = true;
}
if (e.KeyChar == '.' && txtPrice.Text.IndexOf('.') > -1)
{
e.Handled = true;
}
}
