int i = Convert.ToInt32(TextBox1.Text); Label1.Text = i.ToString();

No need for this, Just write, Label1.Text = TextBox1.Text;

He wants to write a calculator, where he can type into a textbox "1+2-3*4" and it does the calculating for him. ie/ you've totally misunderstood the point!

If you'd followed the link you'd have found a whole article about one. I'm curious as to why you voted me down for pointing you towards the answer.

Include a reference to his assembly in your project and then do the following:

ExpressionEval eval = new ExpressionEval(txtFunction.Text);
object output = eval.Evaluate();
if (output != null)
{
  // You have your answer. Do what you want with it.
}
