Need help converting js to C

Hi!

original js script:

 #pragma strict
 #pragma implicit
 #pragma downcast
 //this script is attached every ball and it must be disabled, clickdetecting script will enable this
 var particle:GameObject;
 private var count:boolean=true;
 
 function Start()
 {
 var container = GameObject.Find("Container"); //container which contains ball's objects
  rigidbody.position = Vector3(rigidbody.position.x,rigidbody.position.y, 0);
    var myPos : Vector3 = transform.position; 
  
    for (var child : Transform in container.transform) //check if there is same tagged ball near this ball 
    {  
       var t : Transform = child.transform; 
       t.position.z=0;
       myPos.z=0;
     distance = (t.position - myPos).sqrMagnitude;     
     
       if (distance>0.0001 && distance <0.1 &&  gameObject.tag==child.gameObject.tag) //if distance is less then 0.1 between same balls
       {
         child.gameObject.GetComponent.<chack>().enabled=true; //enable same ball's "chack" script
         var modifiedColors : Color[] = particle.GetComponent.<ParticleAnimator>().colorAnimation; //get particle color and modify it to match this ball's color
         modifiedColors[0] = renderer.material.color;
         modifiedColors[1] = renderer.material.color;
         modifiedColors[2] = renderer.material.color;
         modifiedColors[3] = renderer.material.color;
         modifiedColors[4] = renderer.material.color;
         particle.GetComponent.<ParticleAnimator>().colorAnimation = modifiedColors; //give particle modified color
         var particle=Instantiate(particle, transform.position, transform.rotation); //instantiate particle
 
         if(count){
         clickdetecting.destroyed++;
         if(Time.timeScale != 0){
         Camera.main.GetComponent.<clickdetecting>().scoresCalculation();//call clickdetecting script which is attached to main camera
         }
         count=false;
         }
         Destroy(gameObject);
          }
       } 
       
 }

Converted to C# ... fixed what i can:

 using UnityEngine;
 using System.Collections;
 
 public class chack : MonoBehaviour {
 
 
 
 //this script is attached every ball and it must be disabled, clickdetecting script will enable this
 GameObject particle;
 private bool  count=true;
 
 void Start (){
 GameObject container= GameObject.Find("Container"); //container which contains ball's objects
  rigidbody.position = new Vector3(rigidbody.position.x,rigidbody.position.y, 0);
    Vector3 myPos = transform.position; 
  
    foreach(Transform child in container.transform) //check if there is same tagged ball near this ball 
    {  
         Transform t = child.transform; 
         t.position = new Vector3(rigidbody.position.x,rigidbody.position.y, 0);
       
         //myPos.z=0;
         myPos = new Vector3(myPos.x,myPos.y, 0);
         
         //
         distance = (t.position - myPos).sqrMagnitude;     
         //error CS0103: The name `distance' does not exist in the current context
         //
         
       if (distance>0.0001f && distance <0.1f &&  gameObject.tag==child.gameObject.tag) //if distance is less then 0.1f between same balls
       {
         //

         if(count){

         count=false;
         }
         Destroy(gameObject);
          }
       } 
       
 }
