I gotta really ask you this ... why did you write your own scanner for 
C# ?.. I think you could have gotten away with a simple flex scanner 
and saved a lot of work and code as well.

You could have gotten away with just

#define CLOSE_AND_OPEN(stream,type,color) \
                do\
                {\
                        if(previous!=TOK_##type)\
                        { \
                                CSSrcGenClosingTag(previous);\
                                CSSrcGenOpeningTag(TOK_##type);\
                                previous = TOK_#type;\
                        }\
                }\
                while(0)

        switch(yylex())
        {
                case TOK_KEYWORD:
                        CLOSE_AND_OPEN(outStream, KEYWORD, "cs-keyword");
                        fputs(yytext,outStream);
                        break;
                        ...
        }

You have spent such a lot of work on the scanner , that HTML gen has 
suffered , so to speak . I can only say that I don't like the HTML it 
generates .. As far as possible , try to stick to XML compatible HTML 
syntax . Your code seems to have gone too deep into <font> hell :-)

Convert all \n into <br/> and all tabs into &nbsp;&nbsp;&nbsp;&nbsp;
etc...

You might even define the formatting as classes and use a .css file to 
set the colors & highlights instead of hard-coding them in HTML ..

<font class="lineno">1 </font>
<font class="cskeyword">using</font> <font class="csidentifier">System</font>
<font class="cspunct">;</font>

Modularize, Simplify and well -- Use the Force ;-)
