Escaping characters in C#

C# defines the following character escape sequences:

• \' - single quote, needed for character literals
• \" - double quote, needed for string literals
• \\ - backslash
• \0 – Null
• \a - Alert
• \b - Backspace
• \f - Form feed
• \n - New line
• \r - Carriage return
• \t - Horizontal tab
• \v - Vertical quote
• \u - Unicode escape sequence for character
• \U - Unicode escape sequence for surrogate pairs.
• \x - Unicode escape sequence similar to "\u" except with variable length.

We can also use the \ escape character to store the string He said "Hi" inside a string variable in C#. We would have to write a \ before each double quote like He said \"Hi\". The following code example shows us how we can escape double quotes with the \ escape character in C#.

string msg = "He said \"Hi\"";
Console.WriteLine(msg);

Output:

He said "Hi"

We saved the string msg with the value He said "Hi" by using the \ escape character in C#.
