by saying:

richtextboxbrowsing.text= 

in each iteration of loop, keep on overwriting text. last call text property gets printed.

you need set richtextboxbrowsing.textmode property multiline, , instead call:

richtextboxbrowsing.appendtext(s + " contains " + val + "\n"); 

oh, , way, use: string val = rk.getvalue(s).tostring();

so can remove int = 0; declaration
