Reading a Text from the Console

To read a text (string) from the console, again, we have to declare a new variable and use the standard command for reading a text from the console:

var str = Console.ReadLine();

By default, the Console.ReadLine(…) method returns a text result – a text line, read from the console.

  • After you read a text from the console, additionally, you can parse the text to an integer by int.Parse(…) or a floating-point number by double.Parse(…).
  • If parsing to a number is not done, each number will simply be text, and we cannot do arithmetic operations with it.

var name = Console.ReadLine();
Console.WriteLine("Hello, {0}!", name);

In this case the {0} expression is replaced with the first passed argument, which holds the variable name. If we enter "John", the output will be as follows:
