Hi I want to convert my Js code to c # It was correct when he wrote in js but not correct in c # Please tell me the correct way

void Brake () {

W_RL.GetGroundHit (out hit);
 var HH = Mathf.Abs (hit.sidewaysSlip);
	if (stop)
	{
	W_FL.brakeTorque = 100;
	W_FR.brakeTorque = 100;
    } 
	else
	{
	W_FL.brakeTorque = 0;
	W_FR.brakeTorque = 0;
	}
	if (C_Speed > 20 && stop && HH >0)
	{
	A_T.volume = 1;
	P_T_L.particleEmitter.emit = true;
	P_T_R.particleEmitter.emit = true;}

The problem is in line 2
How do I define HH?
As a variable

float HH = Mathf.Abs(hit.sidewaysSlip);

Technically your way should be correct in C# too, but I personally really dislike using var.
