visual studio - Im trying to make a write to text file in c# -

i have code doesn't seem doing bit stuck

const string spath = "movieadd.txt"; system.io.streamwriter savefile = new system.io.streamwriter(spath); if (listbox1.selecteditems.count ==1) {      foreach (var item in listbox1.selecteditems)      {           savefile.writeline(item);      }      savefile.close(); } 

the code writes lines when 1 entry in list selected. i'm unsure whether want, considering you're trying write 1 line per selected item. may want rewrite code following, allows more 1 row selected. also, file closed in case in following code.

const string spath = "movieadd.txt"; if (listbox1.selecteditems.count >= 1) {     using (system.io.streamwriter savefile = new system.io.streamwriter(spath))     {         foreach (var item in listbox1.selecteditems)         {             savefile.writeline(item);         }     } } 

another issue may don't have explicit path in spath variable. may cause problems, depending on current working directory, may different directory executable resides in! safer add directory explicitly, this:

const string spath = @"c:\temp\movieadd.txt"; if (listbox1.selecteditems.count >= 1) {     using (system.io.streamwriter savefile = new system.io.streamwriter(spath))     {         foreach (var item in listbox1.selecteditems)         {             savefile.writeline(item);         }     } }
