    private void txtBfrLeft1_Leave(object sender, EventArgs e)
    {
        if (txtBfrRight1.Text != "" || txtBfrLeft1.Text != "")
        {
            int befrAvg1 = (Convert.(txtBfrRight1.Text) + Convert.ToDouble(txtBfrLeft1.Text)) / 2;
            txtBfrAvg1.Text = befrAvg1.ToString();
        }
    }       

Answer 1

Try this:

double befrAvg1 = (new []
{
    double.Parse(txtBfrRight1.Text),
    double.Parse(txtBfrLeft1.Text)
}).Average();

Or if you do actually want the result as an integer then this:

int befrAvg1 = (int)((new []
{
    double.Parse(txtBfrRight1.Text),
    double.Parse(txtBfrLeft1.Text)
}).Average());
