I am using a serialized object to maintain state and to back up a database
incase the SQL server isn't available. I would like to delete the
database.state file I create programmatically when I reinitialize it. I do
this with the File.Delete(String path); static method. I am getting the
following error, even if I close the console application and restart it:
The process cannot access the file
"C:\RAFT.NET\Service\State\Database\Database.state" because it is being used by
another process. System.IO.IOException: The process cannot access the file
"C:\RAFT.NET\Service\State\Database\Database.state" because it is being used by
another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String str)
at System.IO.File.Delete(String path)
at com.TheHartford.HTSC.RAFT.FileWatcher.FileWatcher.loadDatabaseItems() in
c:\raft\filewatcher\code\filewatcher.cs:line 123 mscorlib
This is my serialization method, in which I try to delete the file if it is
present.
public void DoSerialize(String Path, object o) {
lock (syncRoot2) {
try {
DoMessaging("FW000016", Path, DateTime.Now);
FileStream myFileStream = null;
if (!myInstance.DoesFileExist(Path))
myFileStream = File.Create(Path);
else {
if
(Path.Equals(_MyApplicationInitializedData.DatabaseStatePath)) {
File.Delete(Path);
myFileStream = File.Create(Path);
}
else
myFileStream = File.OpenWrite(Path);
}
BinaryFormatter serializer = new BinaryFormatter();
serializer.Serialize(myFileStream, o);
serializer = null;
myFileStream.Close();
myFileStream = null;
DoGarbageCollection();
}
catch (Exception ex) {}
}
}
My question is how can I force a delete or, how can I make sure the file is not
being used by someone. I am positive that at start up, my application is not
using this file; I don't know why it thinks it is being used.
