Regular Strings vs. Verbatim Strings in C#: When Should I Use Which?

Normal strings and verbatim strings in C#

Ordinary strings in C# are enclosed in double quotes and can contain escape characters, such as n for newline and t for tab. Escape characters allow you to represent special characters that the compiler otherwise cannot interpret correctly.

Verbatim strings, on the other hand, start with the @ symbol and are interpreted literally. They are useful when you need to include special characters without having to escape them. For example, to represent a filename that contains special characters, you can use a verbatim string:

<code class="language-csharp">string myFileName = "C:\myfolder\myfile.txt"; // 普通字符串</code>

This code will not compile because the backslash character () is an escape character. To interpret backslashes literally, use a verbatim string like this:

<code class="language-csharp">string myFileName = @"C:\myfolder\myfile.txt"; // 逐字字符串</code>

In this example, the @ symbol tells the compiler to ignore any special meaning of the characters in the string. Therefore, backslashes are interpreted literally as path separators.

Use verbatim strings without escaping special characters, making your code more concise and readable. This is especially useful when working with complex strings or paths that contain multiple special characters.
