What is C# Escape / Unescape?

C# Escape / Unescape converts text to and from the escaped form used inside C# string literals. When you paste raw text, it adds the backslash escapes C# requires — \\ for a backslash, \" for a quote, \n, \r, \t, plus C#-specific escapes like \0, \a and \v — so the result can be dropped straight into double-quoted C# source. Unescape does the reverse, decoding \n, \uXXXX, \xH..H and \UXXXXXXXX back to the original characters.

Everything runs locally in your browser, so code and secrets never leave your machine.

How to Use C# Escape / Unescape

1

Paste your text into the input box

2

Choose Escape to build a C# literal, or Unescape to decode one

3

Optionally enable \uXXXX escaping for non-ASCII characters

4

Copy the output into your C# code

Common Use Cases

  • Embedding a Windows file path or regex into a C# string without breaking it.
  • Pasting multi-line text into a C# string literal safely.
  • Decoding an escaped C# string from a log or config back to readable text.
  • Converting non-ASCII characters to \uXXXX for ASCII-only C# source.

Example Input and Output

Escape a Windows path and a multi-line message for a C# string literal.

Raw text
C:\temp\log.txt
Line two
Escaped C#
C:\\temp\\log.txt\nLine two

How This Tool Works

The tool scans your text character by character, replacing characters that are special in C# string literals with their escape sequences (or reversing that mapping when unescaping), entirely in the browser.

Technical Stack

TypeScriptC# string-literal rulesClient-side processing

C#-specific escapes

Unlike many languages, C# supports \a (bell), \v (vertical tab) and \0 (null), all of which this tool handles.

Privacy

Processing is fully client-side — nothing is sent to a server.

Frequently Asked Questions

Which escapes does it support?

Escaping emits \\ \" \n \r \t \b \f and C#-specific \0, \a, \v. Unescaping also decodes \uXXXX, \xH..H and \UXXXXXXXX.

Does it produce verbatim (@"...") strings?

No. It produces standard double-quoted C# literals. Verbatim strings use different rules and are not generated here.

Will it escape Unicode characters?

Only if you enable the non-ASCII option; otherwise printable Unicode is left as-is, which valid C# source supports.

Is my input uploaded?

No. Escaping and unescaping run entirely in your browser.
