Answer 1

You need to excape it with \

string example = "\"";

or with @ (as Daniel suggested)

string example = @"""";

Answer 2

You need to escape it like this:

var example = "\"";

Or use a verbatim string literal with a double ":

var example = @"""";

Answer 3

" is an escape sequence character.

You need to escape it with \ like;

string example = "\"";

From Escape Sequences

Escape Sequence -- Represents
\"              -- Double quotation mark 

From Wikipedia

In many programming languages escape sequences are used in character literals and string literals, to express characters which are not printable or clash with the syntax of characters or strings. The escape character is usually the backslash. For example the single quotation mark character might be expressed as '\'' since writing ''' is not acceptable.

As an alternative, you can use your string as a verbatim string literal.

From 2.4.4.5 String literals

A verbatim string literal consists of an @ character followed by a double-quote character, zero or more characters, and a closing double-quote character. A simple example is @"hello". In a verbatim string literal, the characters between the delimiters are interpreted verbatim, the only exception being a quote-escape-sequence.

string example = @""";
