To obtain a number that is represented as a string, you can use the
Int32.Parse() method.

Example:

using System;

class Test
{
static void Main()
{
string s = "5";
int i = Int32.Parse(s);
Console.WriteLine(i);
Console.Read();
}
}

You don't cast a string to int - you parse a string to get an integer.
Look at Int32.Parse.

int i = int.Parse( strVar );

Glenn,

The Convert class would be pretty useless in this example, since
the Convert.ToInt32 is only a wrapper for the Int32.Parse method, so
you would only add another call on the equation. That is, unless you
need to convert from a specific base for which the ParseNumber
class will be used.
