Reading and storing variables from data files

[C# Programming]

Hello I am trying to read several different integers from a data file and then store each integer into a different variable.Does anyone know how to do this?

This is my program so far:
class Program
{
static void Main(string[] args)
{
string fileName, num;
int temp;
Console.Write("ENTer filename: ");
fileName = Console.ReadLine();
StreamReader inputFile = new StreamReader(fileName);
num = inputFile.ReadLine();
while (num != null)
{
temp= Convert.ToInt32(inputFile.Read());
Console.WriteLine(num);
num =inputFile.ReadLine();
}
Console.WriteLine("Press enter to end Program");
Console.ReadLine();
}
}
