C#

Hello. i need a help to create a program with C#, which will work like calculator.
User will be able to multiply,subtract, add and so on. It will be even possible to zero it, i mean press a key and everything dissapears.

Implement it in Windows-forms instead of in Console.


I have tried with following, but i of course did not really manage with it.

with best regards Behruz

string number1=Console.ReadLine();
int number1Int=int.Parse(number1);
string number2=Console.ReadLine();
int number2Int=int.Parse(number2);
int answer=number1Int*number2Int;
Console.WriteLine(answer);
Console.ReadLine();
