C# Escape — A Literal That Compiles as Is

What this tool does

It escapes text for a regular C# string literal — the "..." form, not the verbatim @"..." form:

• backslashes are doubled;
• " is escaped; ' is left alone, since it delimits a char, not a string;
• \a (bell), \v (vertical tab) and \0 (NUL) are emitted as named sequences — these three are what distinguish the C# escape set from the JavaScript one;
• newline, carriage return, tab, backspace and form feed get their usual named forms;
• remaining control characters become \uXXXX.

Non-ASCII characters are left as they are: C# sources are UTF-8, and an escaped accent would only hurt readability.

When you need it

Hard-coding a connection fragment, a regex, a file path or a log template into a .cs file. Paths are the common case: \\server\share has to be doubled in a regular literal, and getting it wrong produces a tab or a form feed instead of a directory separator.

What it does not do

It does not choose the literal form for you. If your text is mostly backslashes — a Windows path, a regex — a verbatim @"..." literal is usually more readable than the escaped form this tool produces, and it follows a different rule.
