How do I do a RaiseEvent in csharp
I'm ok in VB but csharp confused me a lot.
******* code ********
private FileSystemWatcher watcher = new FileSystemWatcher();
public delegate void Changed(WatcherChangeTypes exch);
public delegate void Created(string fileName);
public delegate void ReCreated(string OldName, string newName);
public delegate void OverRun(string Message);
public FileWatcher()
{
watcher.Path = "C:\\";
//* Watch for changes in LastAccess and LastWrite times, and
// the renaming of files or directories. */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch text files.
watcher.Filter = "*.txt";
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnCreated);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
watcher.Error += new ErrorEventHandler(OnError);
// Begin watching.
watcher.EnableRaisingEvents = true;
}
protected virtual void OnChanged(object sender, FileSystemEventArgs e)
{
///////////////////////////////////////// THIS IS WHERE IT DOESN'T WORK
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//Changed(e.ChangeType);
}
protected virtual void OnCreated(object sender, FileSystemEventArgs e)
{
///////////////////////////////////////// THIS IS WHERE IT DOESN'T WORK
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//RaiseEvent Created(e.FullPath);
}
protected virtual void OnRenamed(object sender , RenamedEventArgs a)
{
///////////////////////////////////////// THIS IS WHERE IT DOESN'T WORK
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
//RaiseEvent ReCreated(e.OldFullPath, e.FullPath);
}
Thank you

You havent declared an event of type one of your delegates in your code.
eg
public event Changed FileWatcherChanged;
and you raise this
protected virtual void OnChanged(object sender, FileSystemEventArgs e)
{
changed(e.ChangeType);
}

Thanks, but now how do I call those functions from another form as all this
is in a dll now.
This is what I had in VB
////////////////// CODE \\\\\\\\\\\\\\\\\\\\
Imports it
Dim fw As New it_FileWatcher.FileWatcher()
AddHandler fw.Changed, AddressOf onChange
Sub onChange(ByVal changeType As System.IO.WatcherChangeTypes, ByVal
filename As String)
System.Diagnostics.Process.Start(filename)
End Sub
what should I do to get the same in csharp???
Thank you very much for the help.

Hi Nicolas
I think this is what your after.
it_FileWatcher.FileWatcher fw = new it_FileWatcher.FileWatcher();
fw.Changed += new it_FileWatcher.Changed(onChange);
private void onChange(System.IO.WatcherChangeTypes change, string filename)
{
System.Diagnostics.Process.Start(filename);
}
