What are Escape Sequences?

An escape sequence is a series of characters that begins with a backslash ( \ ), followed by combination of one or more letters or digits. To represent a newline character, single quotation mark, or certain other characters in a character constant, you must use Escape Sequences. 

Note: 

a. Escape sequence work only during run-time.

b. They always have to enclose within double quotes.

What are the various escape sequences that are available in C#?

The various escape sequences that are available in C# are as follows: 

1. To provide Single Quote

This escape sequence ( \' ) is used to put your string value or variable value into single quote.  

Practical Implementation:
 

using System;

namespace AspnetSolutions
{
    class stringEscapeSequences
    {
        public static void Main()
        {

            /*To provide Single Quote*/
            Console.WriteLine("\'Imaginationhunt\'");

            /*Or single quote to variables*/
            string str1 = "Imaginationhunt";
            Console.WriteLine("\'" + str1 + "\'");

         }
    }
}

2. To provide Double Quote

This escape sequence ( \" ) is used to put your string value or variable value into double quote.

Practical Implementation:

using System;

namespace AspnetSolutions
{
    class stringEscapeSequences
    {
        public static void Main()
        {

            /*Double Quote to hard coded string*/
            Console.WriteLine("\"Imaginationhunt\"");

            /*Or double quote to variables*/
            string str2 = "Imaginationhunt";
            Console.WriteLine("\"" + str2 + "\"");

        }
    }
}

3. To provide Backslash

This escape sequence ( \\ ) is mainly used in path. We input (\\) and at run-time it change to slash (\) between directories so as to separate them.
 

Practical Implementation:

using System;

namespace AspnetSolutions
{
    class stringEscapeSequences
    {
        public static void Main()
        {

            /*To provide Backslash*/
            Console.WriteLine("C:\\Abc\\Def");

        }
    }
}

If we directly give the path as C:\Abc\Def, we get a compile time error which says that unrecognized escape sequence.
