A quick question. How do you allow a user to enter in a number through the command window? (This is for a basic addition console program I am creating in C#)

Look up Console.ReadLine().

You could also use Console.In if you prefer more control.

If you decide to read it as a string, you can use Convert.ToInt32() or int.Parse() to try to convert it.

There's also:

int number = Integer.Parse(Console.ReadLine());


It'll throw an exception if they enter the incorrect formatting. So I'd use something like:


int number = 0;
bool done = false;
while(done == false)
{
try
{
Console.Write("Enter a number: ");
number = Integer.Parse(Console.ReadLine());
done = true;
}
catch
{
Console.WriteLine("I said enter a number, silly!");
}
}
Console.WriteLine("You entered: " + number);

Just wondering if there's a TryParse in Integer or perhaps double that you can use instead? That's the preferred way.
