Accepted answer
To make sure you don't get an error when the textbox is empty or doesn't contain a number, I'd write the code like this. Zero will then be substituted for an invalid value:

decimal a, b, c;
Decimal.TryParse(textBox1.Text, out a);
Decimal.TryParse(textBox2.Text, out b);
c = a + b;
label1.Text = c.ToString();

Writing above code on page load is not going to work as initially your text boxes are empty, which will give you error while conversion. You need to write your code either on some button click or on textchanged event.

Use this code

private void button1_Click(object sender, EventArgs e)
{
            double a, b,c;
            a = Convert.ToDouble(textBox1.Text );
            b = Convert.ToDouble(textBox2.Text);
            c = a + b;
            label1.Text = c.ToString();
}

I am embedding the Source Code also you can download it.

            decimal add;
            add=Convert.ToDecimal( textBox1.Text) +Convert.ToDecimal( textBox2.Text);
            label3.Text = add.ToString();

you can do like that

System.Decimal d = System.Decimal.Add(4.61m, 4.61m);
result is 9.22
