How to take a snapshot with Ozeski SDK USB Camera?

Question

I'm quite newbie in programming, but triyng to run my first app in VS2019, C# .NET. I want to take a snapshop from my USB microscope. I've found OZEKI SDK library and I'm able to connect and view image from microscope. Ozeki has a tutorial on youtube:

https://www.youtube.com/watch?v=xjMAfMAix9c

and their website,

https://www.camera-sdk.com/p_6553-how-to-take-a-picture-snapshot-and-save-it-as-.jpg-in-c-.html

but when I tried to run app, I got message: " images.save(curentpath)" object does not contain a definition for 'save' and no accesible...."

Thanks in advance for any help.

OK, I did it. Change:

var snapShotImage = _snapshotHandler.TakeSnapshot().ToImage();

to

var snapShotImage = _snapShot.TakeSnapshot().ToImage() as System.Drawing.Image;
