 Posted: Sat Oct 25, 2008 9:47 am Post subject: C# int conversion. |
 |
|
| Code: |
Console.WriteLine(
" *****************************************************"
);
Console.WriteLine(
" * [Stefon]'s Addition *"
);
Console.WriteLine(
" * Calculator *"
);
Console.WriteLine(
" *****************************************************"
);
Console.WriteLine("");
Console.WriteLine("Please enter two numbers that will be added together");
Console.WriteLine(" ");
Console.Write("Number 1: ");
string num1 = Console.ReadLine();
Console.Write("Number 2: ");
string num2 = Console.ReadLine();
string sum = num1 + num2;
Console.WriteLine(sum);
Console.ReadLine(); |
If you ran this code and the two numbers you entered were "4" and "5" the output would be "45". The output I want is "9". I know what I got to do. I got to get num1 and num2 and sum to be a int. But the contents of a Console.ReadLine(); cannot be an int. So I have it as as string right now.
So how do I convert my strings into an int.

A simple google search would have sufficed.  ToDecimal(String) or Int32.Parse(input); or ToUInt32(String)

Not quite.
Console.Read() returns one char, and it'll return the ASCII value, not the actual integer that the symbol represents.

Really? Mine's returning the numerical value..
If i type in 1337, it doesn't come out as 49(ASCII for 1), it comes out 1337.
Weird.
