I have the following method in a utility class I created that is instantiated
via a singleton. I think begin my file work load that can be 100 files... I
start 10 threads that do a copy, rename, delete, script work load. During
these threads I create files based on the work item's ID for example
S053R.state with the method below. Every step of the way I call the below
method to serialize an object to maintain state incase the system goes down or
the transfer fails.
My questions:
1. Why do I keep getting the:
2005-11-17 14:22:40,305 [2096] ERROR
com.TheHartford.HTSC.RAFT.FileWatcher.Utilities [(null)] -EXCEPTION: Access to

at com.TheHartford.HTSC.RAFT.FileWatcher.Utilities.DoSerialize(String Path,
String Name, Object o) in c:\raft\filewatcher\code\utilities.cs:line 438
2. would it be better to create a state engine using MSMQ instead?
Any help would be greatly appreciated; I have been struggling with this one for
a while. I feel like I am closing everything and I know this is the only
method and process that creates and deletes these files.
public void DoSerialize(String Path, String Name, object o) {
lock (syncRoot2){
try{
object j = new object();
j = o;
DirectoryInfo di = new DirectoryInfo(Path);
FileInfo[] finfos = di.GetFiles(Name);
for(int i = 0; i < finfos.Length; i++){
FileInfo file = finfos[i];
try{
file.Delete();
}
catch (FileNotFoundException fnfe){
log.Error("FILE NOT FOUND: " +
fnfe.ToString() + " " + fnfe.Message);
}
catch (IOException fnfe){
log.Error("IO EXCEPTION: " +
fnfe.ToString() + " " + fnfe.Message);
}
}
FileInfo fi = new FileInfo(Path + Name);
using (Stream myFileStream = fi.Create()){
SoapFormatter serializer = new SoapFormatter();
serializer.Serialize(myFileStream, j);
DoGarbageCollection();
}
}
catch (Exception ex){
DoMessaging("FWE00017", ex.Message + " " + ex.ToString(),
GetDateNowDateTime());
log.Error("EXCEPTION: " + ex.Message + " " + ex.ToString());
}
}
