Disconnect, then reconnect pin

I'm using DirectShow.net and SlimDX to put a video texture on a quad. I've got a problem on device lost. I'm not able to reset my device. After hours of googling, I've find a forum topic where the solution was to disconnect the vmr9 pin, reset 开发者_运维知识库the device and reconnect the pin.

I know how to disconnect :

IPin pin;
vmr9.FindPin("VMR Input0", out pin);
pin.Disconnect();

and with this, reset is OK, but how can I connect again ?

OK, found this :

IPin pin;
IPin receivePin;
vmr9.FindPin("VMR Input0", out pin);
pin.ConnectedTo(out receivePin);
pin.Disconnect();
receivePin.Disconnect();

To reconnect :

pin.Connect(receivePin, null);

Seems to work.
