A faster way to compare point to each corner?

Is there a nicer way to compare a point to each corner of a rect? I need to check if the green point is within the rect before allowing code to run.

Comparing four corners one by one at the moment :

 ...
                if (x > _contraintCorners[0].x && y > _contraintCorners[0].y &&
                    x < _contraintCorners[1].x && y > _contraintCorners[1].y &&
                    x > _contraintCorners[2].x && y < _contraintCorners[2].y &&
                    x < _contraintCorners[3].x && y < _contraintCorners[3].y)
                {
                    //Do movement
                }

Unity has an in-built function:

I don’t know if it’s more performant, but it’s certainly faster to type.

Don’t you only need to compare with two of the four corners (any two corners diagonal from each other)?

Yes you’re right, thank you!
