C# User Interactive Inputs

C# User Interactive Inputs

Different ways for giving value to the variable are,

  • Using an assignment statement
  • Using command line arguments
  • Using user interactive input

System.Console class provides Read, ReadLine and ReadKey methods to read user inputs.

    System.Console.ReadLine();

C# Program for User Interactive Input Example

This C# program uses Console.ReadLine method to read the string value and assigns to string text variable.

    /*
 This C# program for user input
 Also added single and multiline comments.
 */
using System; // System is a namespace

public class InteractiveInput
{
    // Main method which starts the program execution.
    public static void Main()
    {
        Console.Write("Enter text: ");
        string text = Console.ReadLine();
        // Prints welcome text
        Console.WriteLine("Text : " + text);
        // Waits till any key press
        Console.ReadKey();
        
    }
}

Output:

C:> csc InteractiveInput.cs
C:> InteractiveInput
Enter text: Welcome to codingpointer.com to learn C#
Text : Welcome to codingpointer.com to learn C#

C# Program with Multple User Inputs

This C# program reads multiple user inputs and prints the user inputs.

    /*
 This C# program Using alias for System namespace classes
 Also added single and multiline comments.
 */
using System; // System is a namespace

public class InteractiveInput
{
    // Main method which starts the program execution.
    public static void Main()
    {
        Console.Write("Enter text1: ");
        string text1 = Console.ReadLine();
        Console.Write("Enter text2: ");
        string text2 = Console.ReadLine();
        // Prints text1
        Console.WriteLine("Text1 : " + text1);
        // Prints text2
        Console.WriteLine("Text2 : " + text2);
        // Waits till any key press
        Console.ReadKey();
        
    }
}

Output:

C:> csc InteractiveInput.cs
C:> InteractiveInput
Enter text1: welcome to codingpointer.com
Enter text2: testing interactive input program
Text1 : welcome to codingpointer.com
Text2 : testing interactive input program
