Is there a way to detect if an object is already disposed? An an example would be

```auto
$Watcher=New-Object -TypeName System.IO.FileSystemWatcher -Property @{
    Path="C:\"
    Filter="Test.txt"
    IncludeSubdirectories=$false
    NotifyFilter=[IO.NotifyFilters]::FileName, [IO.NotifyFilters]::LastWrite
}

```

I checked a few other forums and some came up with this:

```auto
$watcher -is [System.IDisposable]

```

But I believe that only detects if an object has the Dispose method. Does anyone have any ideas?

You would want to put a try/catch block around the code where an object may already be disposed. The catch type should be `catch [System.ObjectDisposedException] {...` then reinitialize the object for use.

When I dispose that object, I use:

```auto
$Watcher.Dispose()

```

I wouldn’t get an exception cause the Dispose method’s definition is:

```auto
void Dispose()
void IDisposable.Dispose()

```

I tried it to verify it was gonna work using this:

```auto
Try
{
    $Watcher.Dispose()
} 

Catch [System.ObjectDisposedException] {
    "An exception has been caught 1"
}

Catch {
    "An exception has been caught 2"
}

```

My console is blank and do not see any messages.
