How Can I Properly Include a Backslash in a C# String?

Including backslashes in C# strings

When writing a string that contains a backslash character (), such as C:UsersUserNameDocumentsTasks, you may encounter an "unrecognized escape sequence" error.

The special status of backslash in strings

In C# strings, the backslash character acts as an escape character to represent special characters such as newlines and tabs. For example, "n" represents a newline character.

Escape backslash character

To include literal backslashes in a string, you have two options:

1. Double backslash: Use two backslashes, for example:

<code class="language-csharp">var s = "\Tasks";</code>

2. Verbatim string: Use a verbatim string, represented by the @ notation, which ignores escape sequences:

<code class="language-csharp">var s = @"\Tasks";</code>

While escaping backslashes is technically possible, it is generally recommended to use verbatim strings for file/folder paths as it simplifies the syntax and prevents errors.

Alternative: Path.Combine

An alternative to manually handling backslashes is to use the Path.Combine utility method. It automatically ensures that the path is correctly combined with the correct slashes:

<code class="language-csharp">var path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Tasks");</code>

This approach eliminates worries about escaping backslashes and ensures the path is constructed correctly.
