C# String.Length from Microsoft Documentation

Question

Microsoft documentation states that this code will return 7 characters

The Length property returns the number of Char objects in this instance, not

Answer 1

You would have to prevent the interpretation of the literal by the compiler. This can be done with the @ prefix, like this:

var characters = @"abc\u0000def";

The Length property of this string will then return 12, but there will no longer be an actual unicode character in the string.
