In this source code example, we demonstrate how to read values from the console or how to get user input.

We use the Console class to read values.

C# User Input Example

The below C# program reads a value from a console and prints it:

using System;

class Program {
  static void Main() {
    Console.Write("Enter your first name: ");
    string firstName = Console.ReadLine();
    
    Console.Write("Enter your last name: ");
    string lastName = Console.ReadLine();
    
    Console.Write("Enter your age: ");
    string age = Console.ReadLine();
    int intAge = Convert.ToInt32(age);
    
    Console.WriteLine($" First name : {firstName}");
    Console.WriteLine($" Last name : {lastName}");
    Console.WriteLine($" Age : {intAge}");
  }
}

Output:

Enter your first name: Ramesh
Enter your last name: Fadatare
Enter your age: 30
 First name : Ramesh
 Last name : Fadatare
 Age : 30

The {firstName}, {lastName} and {intAge} specifier is replaced with the value of the firstName, lastName and intAge variable.
