How to Properly Handle Backslashes in C# Strings?

Writing Backslashes in Strings

You encounter an "Unrecognized escape sequence" error when attempting to use a backslash character () in a string, such as in a file path. This occurs because the backslash is an escape character reserved for special characters like newlines and tabs.

Solution 1: Double Backslashes or Verbatim String

To include a backslash character itself in a string, you can use two backslashes () or utilize the @ verbatim string syntax, which ignores escape characters:

var s = "\Tasks";
// or 
var s = @"\Tasks";

Solution 2: Path.Combine

Another approach is to utilize the Path.Combine utility method. It seamlessly combines path segments, automatically handling backslashes:

var folderPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filePath = Path.Combine(folderPath, "Tasks");

Recommended Practice: Verbatim Strings

Most C# developers prefer using verbatim strings for building paths since it eliminates the need for double backslashes and allows for straightforward path copying and pasting.

Note on Path.Combine

While using verbatim strings is generally advisable, Path.Combine offers an alternative solution that alleviates concerns about incorrect backslash handling when combining path segments.
