Interacting with the User

To make programs interactive, we need to take input from the user.

Using Console.ReadLine()

This method reads a line of text as a string.

csharp Console.WriteLine("Enter your name:"); string userName = Console.ReadLine(); Console.WriteLine("Hello " + userName);

Important: Type Conversion

Since ReadLine() returns a string, you must convert it if you want numbers: csharp Console.WriteLine("Enter age:"); int age = Convert.ToInt32(Console.ReadLine());
