Usage of @ in c#

The @ symbol in C# is used to create verbatim strings, that is, strings that do not escape special characters, including double quotes, backslashes, tabs, newlines, and carriage returns. This simplifies the content of strings containing special characters and improves readability, but compiler behavior will be affected. When using @ strings, be careful not to use string interpolation to create or concatenate with non-verbatim strings.

Advantages:

Using verbatim strings can simplify strings that contain special characters. It also improves readability because escape sequences are not required to escape the characters. Disadvantages:

Since the @ symbol indicates that the string is a verbatim string, it affects the behavior of the compiler. Therefore, you need to pay attention to the following points when using verbatim strings:

Cannot use string interpolation to create verbatim strings

Cannot concatenate verbatim strings with non-verbatim strings
• ##Example:

Create a verbatim string containing double quotes:

<code class="csharp">string verbatimString = @"字符串包含 ""双引号""";</code>
