Help Converting JS to C# please

Found some scripts I want to use but they're all in js and my entire project is C#.
Only one I am not sure of is this one for the crosshair.
If anyone could help please it would be great.

Code (JavaScript):

1. @script ExecuteInEditMode()
2. var crosshair : Texture2D;
3.  
4. function OnGUI () {
5.     var w = crosshair.width/2;
6.     var h = crosshair.height/2;
7.     position = Rect((Screen.width - w)/2,(Screen.height - h )/2, w, h);
8.  
9.     if (!Input.GetButton ("Fire2")) {
10.         GUI.DrawTexture(position, crosshair);
11.     }
12. }    

Only one part that I am not really sure what to do with is the 2 vars in the OnGUI function.

Code (JavaScript):

1. function OnGUI () {
2.     var w = crosshair.width/2;
3.     var h = crosshair.height/2;

Not sure what to call them in C#.

 

var should work

 

w and h are floats.

float w = crsoshair.width / 2;
etc

Automatic converter if you need (It doesn't do variable types, but like I said those 2 are floats)

you mean ints

 

Oops, my bad, I do

 

Thanks a bunch for the help both of you.

I knew about that converter already and use it when I get stumped but like you said it won't fix everything.
