# Change citation style from square brackets to forward slashes with Biblatex

How can I change the style of citation in Biblatex from [1] to /1/ in both citing within the document as well as in the references at the end of the document? I found some Information ragarding changes for BibTex, but not for BibLaTex. I also managed to change it to backslashes.

MWE for standard numeric-comp:

\documentclass{scrreprt}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage[style=numeric-comp]{biblatex}

\begin{document}
\cite{spiegelberg}
\printbibliography
\end{document}


This is easy if you don't need to change \textcite as well

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage[style=numeric-comp]{biblatex}

\newrobustcmd*{\mkbibpairedslashes}[1]{/#1/}

\DeclareFieldFormat{labelnumberwidth}{\mkbibpairedslashes{#1}}
\DeclareFieldFormat{shorthandwidth}{\mkbibpairedslashes{#1}}

\DeclareCiteCommand{\cite}[\mkbibpairedslashes]
{\usebibmacro{cite:init}%
\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{cite:comp}}
{}
{\usebibmacro{cite:dump}%
\usebibmacro{postnote}}

\begin{document}
\cite{spiegelberg}
\printbibliography
\end{document}
