C# Calculator, textbox coding.

flaxe · 09-11-2009, 09:32 AM

Hello!

I've just learned some C# programming at school and today we did a very simple calculator ;)

Well, when I came home today I was thinking of learn me some more C#, and specially make my calculator more advanced.

Well, my code works, but I wan't it to be some shorter. I've tried it pretty much different until I even got it to work correctly ^^

This is my code line for the button:

Code:

textBox3.Text = Convert.ToString(double.Parse(textBox1.Text) + (double.Parse(textBox2.Text)));

What I want is to shorten that line some, I think it possible...

Anyone know how to make that code shorter but still with the same function/"base code"?

I would also like to know how I can make like when I'm writing '10' in the textBox1, and pressed the PLUS button, then the number '10' in the textBox will be removed so I can write another, and then press the Answear button, I think I have to set an variable for that to work, so the numbers got a place to save. I hope you understand what I mean ;P
