The Convert Class

What's your name?

            string name;

     Console.WriteLine("What is your name");

     name = Console.ReadLine();// This will create the user input at enter

     Console.WriteLine("Hello " + name);

     Console.Read();

What's your number- ..hold up I gotta convert the string

            int celly;

     int homePhone;

     Console.WriteLine("What is your cell number?");

     celly = Convert.ToInt32(Console.ReadLine());// the readline is for text input, so any integers need to be converted.

     Console.WriteLine("What is your home number?");

     homePhone = Convert.ToInt32(Console.ReadLine());

     Console.WriteLine("Your cell number is " + celly + " and your home number is " + homePhone);
     Console.WriteLine("These numbers added together is " + (celly + homePhone));
// note "+ (celly + homePhone)" in parentheses  If this were done without parentheses, this would simply concatenate the variables to the writeline string instead of performing the math operation.

     Console.Read();

Double
     double myDoubleVar;
     myDoubleVar = Convert.ToDouble(Console.ReadLine());

Floats
     double myFloatVar;
     myFloatVar = (float)Convert.ToDouble(Console.ReadLine());
