i'm trying write file names in "filelist.txt".the file has been created when seek write in , shows me error above. should do?

string strfilepath; //the current path : "r:\mft classes\c# fundamental\c#.net apps\employeeinfo\windowsformsapplication2\bin\debug" strfilepath = directory.getcurrentdirectory(); strfilepath = directory.getparent(strfilepath).tostring(); strfilepath = directory.getparent(strfilepath).tostring(); strfilepath = directory.getparent(strfilepath).tostring(); strfilepath = strfilepath + "\\filelist.txt"; file.create(strfilepath); foreach (string saveme in listbox1.items) { file.writealltext(strfilepath, saveme); }

use stream author instead.

string strfilepath; //the current path : "r:\mft classes\c# fundamental\c#.net apps\employeeinfo\windowsformsapplication2\bin\debug" strfilepath = directory.getcurrentdirectory(); strfilepath = strfilepath + "\\filelist.txt"; using (streamwriter sw = new streamwriter(strfilepath, true)) { foreach (string saveme in listbox1.items) { sw.write(saveme); } }
