How to read data from console ?

One of my friend asked me this question today morning and I was bit surprised. I mixed up things saying it must be something like scanf statements. Then I searched it and figured out the steps to do so.

In this code, Console.ReadLine() will accept an input from the keyboard and it will store it in specified variable. Here I wanted to read an integer value from keyboard, so I used Console.Read() first. Console.Read() accepts one character at a time. So it is of new use for accepting integer value. Int32.TryParse() function accepts the value and tries to convert it to integer. This function returns boolean value as success or failure.
