How to Include Double Quotes Inside String Variables in Programming?

Include double quotes in string variables

In programming, when dealing with string variables, you often need to include double quotes in the variable itself. However, this can be a challenge since double quotes are used to delimit strings.

Suppose there is an empty string variable named "title". The goal is to display its content inside a div element, enclosed in double quotes. A simple attempt might look like this:

<code>...
<div>"+ title +@"</div>
...</code>

However, this approach fails because the compiler interprets double quotes in the string as the end of the string delimiter. To solve this problem, you need to escape the double quotes by doubling them (a verbatim string literal):

<code>string title = @""""How to add double quotes"""";</code>

This instructs the compiler to treat double quotes as part of the string rather than as a delimiter. Alternatively, using a normal string literal, you can use backslash() to escape the double quotes:

<code>string title = "\"How to add double quotes\"";</code>

In C# 11, a new feature called raw string literals provides a convenient way to include double quotes in a string:

<code>string title = ""
    "How to add double quotes"
"";</code>

By leveraging these techniques, developers can effectively include double quotes in string variables, meeting the requirement to display specific content enclosed in quotes in HTML elements.
