Welcome to The Coding College! At thecodingcollege.com, we believe in making coding concepts simple and practical. In this tutorial, we’ll focus on C# Output—how to display information using one of the most commonly used methods: Console.WriteLine
.
What is C# Output?
In C#, output refers to the process of displaying information from your program to the user. This is typically done using the console, which is a text-based interface for interacting with your program.
The Console Class
The Console
class, part of the System
namespace, is used for input and output operations in a C# program. The two primary methods for output are:
Console.WriteLine
: Outputs text followed by a new line.Console.Write
: Outputs text without adding a new line.
Example of Console.WriteLine
Here’s a basic example to display a message:
using System;
class Program
{
static void Main()
{
Console.WriteLine("Welcome to The Coding College!");
}
}
Output:
Welcome to The Coding College!
Using Console.Write
The Console.Write
method prints text without adding a new line:
using System;
class Program
{
static void Main()
{
Console.Write("Hello, ");
Console.Write("World!");
}
}
Output:
Hello, World!
Formatting Output
C# allows you to format output by embedding variables or expressions within strings using placeholders or interpolation.
1. Using Placeholders
using System;
class Program
{
static void Main()
{
int age = 24;
Console.WriteLine("I am {0} years old.", age);
}
}
Output:
I am 24 years old.
2. Using String Interpolation
String interpolation provides a cleaner way to include variables directly in a string.
using System;
class Program
{
static void Main()
{
string name = "Naman";
Console.WriteLine($"Hello, {name}! Welcome to The Coding College.");
}
}
Output:
Hello, Naman! Welcome to The Coding College.
Printing Multiple Lines
You can print multiple lines using \n
(newline character) or separate Console.WriteLine
statements.
Example:
using System;
class Program
{
static void Main()
{
Console.WriteLine("Welcome to The Coding College.\nLearn to code step by step.");
Console.WriteLine("Happy Coding!");
}
}
Output:
Welcome to The Coding College.
Learn to code step by step.
Happy Coding!
Printing Special Characters
C# provides escape sequences to print special characters:
- New Line (
\n
): Moves to the next line. - Tab (
\t
): Adds a tab space. - Backslash (
\\
): Prints a backslash. - Double Quotes (
\"
): Prints double quotes.
Example:
using System;
class Program
{
static void Main()
{
Console.WriteLine("This is a backslash: \\");
Console.WriteLine("This is a tab:\tHello!");
Console.WriteLine("This is a quote: \"C#\"");
}
}
Output:
This is a backslash: \
This is a tab: Hello!
This is a quote: "C#"
Output Best Practices
- Use Descriptive Messages: Ensure your output provides clear and meaningful information.
- Format Dynamically: Use string interpolation for readability.
- Add Line Breaks: Make output more readable by spacing logically.
