How to Properly Escape Double Quotes in Strings for Display?

Cleverly handle double quotes in variable strings

In programming, it is often necessary to enclose the string stored in a variable in double quotes and display it in other strings. This article explores effective ways to achieve this goal.

Suppose you have a string variable title that is initially an empty string. To display its content inside a <div> element, you try concatenating double quotes and the variable like this:

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

However, this approach results in the double quotes not being escaped, resulting in unexpected behavior. To display quotes correctly, they need to be escaped.

Escape of double quotes

Use verbatim string literals:

One solution is to use a verbatim string literal, which starts with an @ symbol followed by a double quote. They allow special characters (including double quotes) to be used without escaping.

<code>string str = @""""How to add doublequotes""""";</code>

Use standard string literals and escape sequences:

If you prefer standard string literals, you can escape double quotes using the backslash () character.

<code>string str = "\""How to add doublequotes\""";</code>

Update: C# 11 native string literals

In C# 11 and later, you can use native string literals to simplify the process of embedding double quotes. They allow you to specify strings without escape sequences.

<code>string str = """
"How to add doublequotes"
""";</code>

These methods allow you to successfully display strings containing double quotes in your code, ensuring accurate representation of the data.
