Sometimes, you want to store quotation marks within a string, as in the following example

"Alive", she cried!

In C#, there are at least 4 ways to embed a quote within a string:

1. Escape quote with a backslash
2. Precede string with @ and use double quotes
3. Use the corresponding ASCII character
4. Use the Hexadecimal Unicode character

Escape with backslash

You can precede any escaped character with a backslash ("\") to preserve that character.

For example:

var lyrics = "\"Alive\", she cried!"
  

Precede with @ and use double quotes

If you precede the string with the "@" character, you can use a double set of quotation marks to indicate a single set of quotation marks within a string.

For example:

var lyrics = @"""Alive"", she cried!"
  

Use the ASCII character

A double quote is the ASCII value 34, so you can append this to your string.

For example:

quote = (char)34 + "Alive" + (char)34 + ", she cried!";
  

Use the Hexadecimal Unicode character

You can escape Unicode characters by preceding the hexadecimal value with "\u". The hexadecimal value of a double quote is 0022, so you can include this in your string.

For example:

quote = "\u0022Alive\u0022, she cried!";
  

These techniques work for many other characters that are difficult to represent within quotation marks, such as line feeds, non-English characters, and non-printing characters.
