In VB.NET you can write textBox.Text *= 1.25, but in C# I got this error:
Cannot implicitly convert type 'double' to 'string'

How do you multiply a textbox value with something?

 Hello,
  To convert between for example string and double, you can use these member functions of Double class:

    public static double Parse(string)
    public override string ToString()

private void getValue()
{
     double aa;
     aa = double.parse(this.textBox.text) * 1.25;
     this.textBox.text = aa.ToString();
     
}

That one was silly, I fixed it with this.

eTotal.Text = Convert.ToString(Convert.ToDouble(Convert.ToDecimal(eKWUsage.ToString()) + Convert.ToDecimal(eRate.ToString())));
