Ways to print escape characters in C#

The following are the escape characters in C# and the display column suggests how to use and print them in C# −

Common Escape Characters

The most commonly used escape characters in C# programming are
for new lines, \t for tabs, " for double quotes, and \ for backslashes −

using System;

class Demo {
    static void Main() {
        // Tab character
        Console.WriteLine("Name\tAge\tCity");
        Console.WriteLine("John\t25\tNew York");
        
        // New line character
        Console.WriteLine("First line\nSecond line");
        
        // Quote and backslash
        Console.WriteLine("He said, "Hello World!"");
        Console.WriteLine("File path: C:\Documents\file.txt");
    }
}

The output of the above code is −

Name    Age     City
John    25      New York
First line
Second line
He said, "Hello World!"
File path: C:\Documents\file.txt

Using Unicode Escape Sequences

Unicode escape sequences allow you to represent any Unicode character using \u followed by four hexadecimal digits −

using System;

class UnicodeDemo {
    static void Main() {
        // Unicode characters
        Console.WriteLine("\u0048\u0065\u006C\u006C\u006F"); // Hello
        Console.WriteLine("Copyright symbol: \u00A9");
        Console.WriteLine("Heart symbol: \u2665");
        Console.WriteLine("Degree symbol: 98.6\u00B0F");
    }
}

The output of the above code is −

Hello
Copyright symbol: ©
Heart symbol: ?
Degree symbol: 98.6°F

Verbatim Strings vs Escape Characters

C# provides verbatim strings (prefixed with @) as an alternative to escape characters, particularly useful for file paths and multi-line strings −

using System;

class VerbatimDemo {
    static void Main() {
        // Using escape characters
        string path1 = "C:\Program Files\MyApp\config.txt";
        
        // Using verbatim string
        string path2 = @"C:\Program Files\MyApp\config.txt";
        
        Console.WriteLine("With escapes: " + path1);
        Console.WriteLine("Verbatim: " + path2);
        
        // Multi-line verbatim string
        string multiLine = @"Line 1
Line 2
Line 3";
        Console.WriteLine("\nMulti-line string:");
        Console.WriteLine(multiLine);
    }
}

The output of the above code is −

With escapes: C:\Program Files\MyApp\config.txt
Verbatim: C:\Program Files\MyApp\config.txt

Multi-line string:
Line 1
Line 2
Line 3

Comparison of Methods

Conclusion

Escape characters in C# provide a way to include special characters in strings that would otherwise be difficult to represent. The most common ones are
, \t, ", and \, while Unicode sequences allow representation of any character. Verbatim strings offer an alternative approach for complex paths and multi-line text.
