Detecting when a SerialPort gets disconnected

Question

I have an open SerialPort and receive data through the DataReceived event.

Is there any way to detect if the SerialPort gets d

Answer 1

I also faced the problem of an unhandleable exception (and not being able to detect/circumvent the problem in code) as soon as the USB-Serial adapter had been disconnected. I can confirm that the solution from Mattt Burland works.

Simplified version:

class SafeSerialPort : SerialPort {
    public new void Open() {
        if (!base.IsOpen) {
            base.Open();
            GC.SuppressFinalize(this.BaseStream);
        }
    }

    public new void Close() {
        if (base.IsOpen) {
            GC.ReRegisterForFinalize(this.BaseStream);
            base.Close();   
        }           
    }

    protected override void Dispose(bool disposing) {
        try {
            base.Dispose(disposing);
        } catch (Exception ex) {
            Debug.WriteLine(ex.Message);
        }

    }
}
