[Tex/LaTex] Syntax highlighting in listings for C# that it looks like in Visual Studio

highlightinglistingssyntax

Community,

I want to get my C# listings syntax highlighted like in Visual Studio but I did not get it so far.

Here's an image of the syntax highlighting of Visual Studio:

Here is the code I have:

\documentclass{article}

\usepackage{color}
\usepackage{listings}
\usepackage{courier}

            string path = Path.GetTempPath() + @"\temperatureapp";

            //check if the folder "temperatureapp" exist in the local temp folder (if not create it)
            bool folderExist = System.IO.Directory.Exists(path);
            if (!folderExist)
                System.IO.Directory.CreateDirectory(path);
        }

        private void saveObjectToTemp(object chart, string chartname)
        {
            //path to the tempfolder of this application.
            string path = Path.GetTempPath() + @"\temperatureapp";

            //check if the folder "temperatureapp" exist in the local temp folder (if not create it)
            bool folderExist = System.IO.Directory.Exists(path);
            if (!folderExist)
                System.IO.Directory.CreateDirectory(path);

            Chart tmpChart = (Chart)chart;

            tmpChart.SaveImage(path + @"\" + chartname, ChartImageFormat.Png);

        }
    }
}
\end{lstlisting}


\end{document}

The key words are not correctly identified and colored. Comments are also not identified and colored. (Comment lines in C# start with "//")

Any hints are taken gratefully by me!

You can have a try with my solution (which I found somewhere around this homepage I guess):

\setmonofont{Consolas} %to be used with XeLaTeX or LuaLaTeX
\definecolor{bluekeywords}{rgb}{0,0,1}
\definecolor{greencomments}{rgb}{0,0.5,0}
\definecolor{redstrings}{rgb}{0.64,0.08,0.08}
\definecolor{xmlcomments}{rgb}{0.5,0.5,0.5}
\definecolor{types}{rgb}{0.17,0.57,0.68}

\usepackage{listings}
\lstset{language=[Sharp]C,
captionpos=b,
%numbers=left, %Nummerierung
%numberstyle=\tiny, % kleine Zeilennummern
frame=lines, % Oberhalb und unterhalb des Listings ist eine Linie
showspaces=false,
showtabs=false,
breaklines=true,
showstringspaces=false,
breakatwhitespace=true,
escapeinside={(*@}{@*)},
commentstyle=\color{greencomments},
morekeywords={partial, var, value, get, set},
keywordstyle=\color{bluekeywords},
stringstyle=\color{redstrings},
basicstyle=\ttfamily\small,
}

To be used with:

\begin{lstlisting}[caption=a test for a C$^\sharp$ code, label=lst:test]
\end{lstlisting}

Keywords work just fine. However there are some things not working till now:

  • #region is not set as a keyword. Tried that but didn't succeed.
  • all bright blue stuff (objects) aren't recognized which will be a difficult point. Maybe there is a solution just to recognize e. g. Math. or other often used paths. As most objects are defined by the user, it would be a lot of handwork.
  • quotation marks in strings don't fit the chosen font

Things which could get improved here (but I don't have the time to do it):

  • set ///, <...> and <.../> grey if it doesn't appear after // (where it should keep green). The XML comment itself should stay green.
  • find objects and print them light blue. E. g. private enum Object, public class Object : Object, private virtual Object but private virtual double which are all keywords.
  • find attributes and print them light blue. E. g. [Serializable, CLSCompliant(false)].
  • remember found objects and treat them the same way all over the document.
  • Possibility to define objects manually or to recognize MSDN-objects like Math.

Looks like this until now:
