Converting function variable to CS

Hello guys, usually I don't ask question like this but I'm stuck and could not find any help. I have an enemy AI javascript code and I try to add it's attack function to other C# code. I'm stuck in some place I don't know how to write it in c# so I need help guys.

Js :

 function Attack(){
 
 var Hit : RaycastHit;
 var direction = bulletAccuracy();  // I couldn't know how to write this in CS
 
 // and raycast stuff that I think I can convert
 }
 
 function bulletAccuracy(){
 
 var spX = (1 - 2 * Random.value) * bulletAccuracy; // and this 
 
 // other stuff that I can covert
 }

I tried

 RaycastHit Hit;

for that, and

 Vector3 direction = bulletAccuracy();

but then I couldn't know how to write function bulletAccuracy in js, if I try

 void bulletAccuracy(){
 
 }

and

 IENumarator bulletAccuracy(){
 
 }

I get errors, how can I write I need only these 2-3 lines guys sorry to ask a question like that but I have no choice.
