i'm using code saving logs in may c# monotouch application:

public static void  writeexeption(string message){         string path= storageclass .logspath ;         string filepath= path.combine (path ,"log.txt");         if(!file.exists (filepath )){             using (streamwriter sw = file.createtext(filepath))              {                 sw.writeline ("--------------------------------------------------------------------------" +                               "--------------------");                 sw.writeline("blahblah...");                 sw.writeline ("--------------------------------------------------------------------------" +                               "--------------------");             }            }         using (streamwriter w = file.appendtext(filepath ))         {             log(message , w);         }     }      public static void log(string logmessage, textwriter w)     {         w.write("\r\nlog entry : ");         w.writeline("{0} {1}", datetime.now.tolongtimestring(),                     datetime.now.tolongdatestring());         w.writeline("  :");         w.writeline("  :{0}", logmessage);         w.writeline ("--------------------------------------------------------------------------" +                       "--------------------");     } 

but in application error:

 sharing violation on path 'file path' 

try adding enclose streamwriter appends data in lock statement. first, add object refer to:

static object _locker = new object(); 

then, modify writeexeption method locking last using statement:

lock (_locker) {     using (streamwriter w = file.appendtext(filepath))     {         log(message, w);     } } 

if still doesn't work, means other application using file. if works, means logging on multiple threads.
