How Can I Easily Create Multiline Strings in C#?

Multiline string literals in C#

Creating multi-line string literals in C# can be tedious and requires string concatenation like in the example. However, this is more conveniently achieved using a verbatim string literal.

Verbatim string literal

Verbatim string literals are represented by adding the @ symbol before the opening quote. This allows you to include newlines and other special characters without using escape sequences.

For example, the following code defines a multiline string literal using verbatim syntax:

<code class="language-c#">string query = @"SELECT foo, bar
FROM table
WHERE id = 42";</code>

Advantages of verbatim string literals

• No need to escape newlines and other special characters.
• Make multi-line strings easier to read and maintain.
• Can be used to embed raw data or code snippets.

Restrictions

• Double quotes must still be escaped using characters.
• Verbatim string literals cannot span multiple lines of source code. If you need a string that spans multiple lines, you must use string concatenation.

Example usage

Verbatim syntax can be used in a variety of scenarios, such as defining SQL queries, constructing HTML or XML documents, or embedding code snippets. Here is an example of how to define a multi-line query using verbatim syntax:

<code class="language-c#">string query = @"SELECT *
FROM Users
WHERE Status = 'Active'";</code>

By using verbatim string literals, you can simplify the process of creating multi-line strings in C#, making your code easier to read and maintain.
