How to print a line on the console using C#?

To display a line on the console in C#, we use the Console.WriteLine() method. This method prints text to the console and automatically adds a new line at the end.

Syntax

Following is the syntax for printing a line to the console −

Console.WriteLine(value);

Where value can be a string, variable, or any expression that can be converted to a string.

Using Console.WriteLine() with Strings

The most common use is to print string literals or string variables −

using System;

public class Program {
   public static void Main() {
      string str = "Tom Hanks is an actor";
      Console.WriteLine("Displaying a line below");
      Console.WriteLine(str);
   }
}

The output of the above code is −

Displaying a line below
Tom Hanks is an actor

Using Console.WriteLine() with Different Data Types

The Console.WriteLine() method can print various data types directly −

using System;

public class Program {
   public static void Main() {
      int age = 65;
      double salary = 45000.75;
      bool isActive = true;
      
      Console.WriteLine("Age: " + age);
      Console.WriteLine("Salary: " + salary);
      Console.WriteLine("Active: " + isActive);
   }
}

The output of the above code is −

Age: 65
Salary: 45000.75
Active: True

Console.WriteLine() vs Console.Write()

The difference between Console.WriteLine() and Console.Write() is that WriteLine() adds a new line after printing, while Write() does not −

using System;

public class Program {
   public static void Main() {
      Console.Write("Hello ");
      Console.Write("World!");
      Console.WriteLine();
      Console.WriteLine("Next line starts here");
   }
}

The output of the above code is −

Hello World!
Next line starts here

Comparison of Console Output Methods

Conclusion

The Console.WriteLine() method is the primary way to print lines to the console in C#. It automatically adds a new line after the output, making it perfect for displaying text that should appear on separate lines. Use Console.Write() when you want to print multiple items on the same line.
