		{
            //Equal sign

            n2 = decimal.Parse(textBox1.Text = textBox1.Text);
            
            if (fun == "+")
			 n1 = n1 + n2;

			else
			if (fun == "-") 
			 n1 = n1 - n2;

			else
				if (fun == "*") 
				n1 = n1 * n2;

			else
				if (fun == "/") 
				n1 = n1 / n2;
			textBox1.Text = n1.ToString();

1. what does 'isnt working...notsure why' mean ? if you cant describe the problem adequately, how do you expect us to help ? (Use "Improve solution")

2. this code

if (fun == "+")
 n1 = n1 + n2;

else
if (fun == "-")
 n1 = n1 - n2;

else
    if (fun == "*")
    n1 = n1 * n2;

else
    if (fun == "/")
    n1 = n1 / n2;

one word .. "awful" .. may I suggest

switch(fun)
{
  case "+" : 
    n1 = n1 + n2;
    break;
  case "-" : 
    n1 = n1 - n2;
    break;
  case "*" : 
    n1 = n1 * n2;
    break;
  case "/" : 
    n1 = n1 / n2;
    break;
}

Solution 2

What is this statement supposed to do?

C#

n2 = decimal.Parse(textBox1.Text = textBox1.Text);

Particularly the expression in parentheses.
