Help me please to convert from UnityScript to C#

Hello, everybody!

Just one thing this converter

couldn't convert:

public var convergenceMethod = converge.center;

there is also an enum: enum converge {none,percent,center,click,mouse,object};

and a switch loop going through this enum:

 switch (convergenceMethod) {
             case converge.percent:
                 // calculate negative parallax from percentage
                 cameraParallaxNegative = cameraParallaxTotal*percentageNegativeParallax/100; etc...

I do not understand of which data type is this "convergenceMethod". I will appreciate any help and thank you in advance!
