Re: ASP.NET Application and FileSystemWatcher

Here is what I have done .I have created a class and I instanciate that
class in Application_Start method of my Global.asax ere is the code:

********Gloabl.asax:
//Sets up a wacher on an specific shared folder to pickup zip files

IFPWatcherComponent ifpWacher=new
IFPWatcherComponent(ConfigurationSettings.AppSettings[ "MonitorPath"]);



********MyClass:

/// </summary>
public class IFPWatcherComponent:BusinessObject
{
string PathToMonitor=null;

public IFPWatcherComponent(string PathToMonitor)
{

try
{
this.PathToMonitor = PathToMonitor;
//Check to see if Web.config has appropriate settings
if (this.PathToMonitor.Trim().Length==0 ) return;
// Make a reference to a directory.
DirectoryInfo di = new DirectoryInfo(this.PathToMonitor);
// Create the directory only if it does not already exist.
if (di.Exists == false)
di.Create();
// create an instance of FileSystemWatcher object and assign path to
monitor
FileSystemWatcher watcher = new FileSystemWatcher();
// set necessary filters
watcher.Path = this.PathToMonitor;
//Watch for changes in FileName
watcher.NotifyFilter = NotifyFilters.FileName;
// watch zip files
watcher.Filter = "*.zip";
//Add appropriate event handler
watcher.Created += new FileSystemEventHandler(OnCreated);
watcher.EnableRaisingEvents = true;
}
catch
{
throw;
}
}
private void OnCreated(object source, FileSystemEventArgs e)
{
FileStream oImg=null;
BinaryReader oBinaryReader=null;

Uploader uploader=new Uploader();
uploader.ComeFrom="88";
uploader.Comments="comment";
uploader.CreatedByUser="test";
uploader.FileName=e.Name;

try
{

oImg = new FileStream (e.FullPath,FileMode.Open,FileAccess.Read);
oBinaryReader = new BinaryReader(oImg);
byte[] oImgByteArray = oBinaryReader.ReadBytes((int) oImg.Length);
uploader.FileBody=oImgByteArray;

uploader.RecordType=Business.IFP.RecordType.IFP_UPLOAD;
uploader.Upload();
uploader=null;

}
catch(Exception ee)
{
*******************I don't know how to handle the exception
here??***********************
}
finally
{
if (oBinaryReader!=null) oBinaryReader.Close();
if (oImg!=null) oImg.Close();

}
}
