How Can I Add Double Quotes to Strings Inside Variables in C#?

Add double quotes to string variables in C#

When manipulating strings in C#, you may need to include double quotes in the string. This can get tricky when strings are stored in variables. A common problem is displaying strings in divs where double quotes are required to render the HTML correctly.

For example, given a string variable:

<code class="language-c#">string title = string.empty;</code>

To display the contents of this variable in a div with surrounding double quotes, a simple attempt might look like this:

<code class="language-c#">...
...
<div>" + title +@"</div>
...
...</code>

However, this approach does not produce the expected output because the double quotes in the string are not escaped. As a result, the HTML code will be invalid.

To properly add double quotes to a string inside a variable, they need to be escaped. This can be done in several ways:

1. Use verbatim string literals:

In verbatim string literals, embedded double quotes will be treated as literals, not string delimiters. This can be achieved by adding the @ symbol in front of the string, as shown below:

<code class="language-c#">string str = @""How to add doublequotes"";</code>

2. Use escaped double quotes:

In ordinary string literals, you can use the backslash character () to escape double quotes. For example:

<code class="language-c#">string str = "\"How to add doublequotes\"";</code>

3. Use raw string literals (C# 11 and above):

C# 11 introduces raw string literals, which provide a convenient way to define strings containing special characters without escaping. To use a raw string literal, just add three double quotes in front of the string:

<code class="language-c#">string str = """
    "How to add doublequotes"
    """</code>

By using these techniques, you can correctly add double quotes to strings stored in variables, ensuring proper HTML rendering and accurate string manipulation.
