Field is never assigned to and will always have its default value.

With the help of the smart people here, I have an object pooling script converted from JS to C#. There are some final warnings though preventing the important fields from showing up in the inspector.

Here is the script:

 public class EasyObjectPool : MonoBehaviour {
     private class PoolInfo{
         
         public string poolName;
         public GameObject prefab;
         public int poolSize;
         public bool canGrowPoolSize = true;
         
     }
     
     private class Pool{
         
         private List<PoolObject> list = new List<PoolObject>();
         public bool  canGrowPoolSize;
         
         public void  Add (PoolObject poolObject){
             list.Add(poolObject);
         }
         
         public int Count (){
             return list.Count;
         }
         
         
         public PoolObject ObjectAt ( int index  ){
 
             PoolObject result = null;
             if(index < list.Count) {
                 result = list[index];
             }
             
             return result;
             
         }
     }
     static public EasyObjectPool instance ;
     PoolInfo[] poolInfo;
     
     private Dictionary<string, Pool> poolDictionary  = new Dictionary<string, Pool>();
 
     
     void Start () {
         
         instance = this;
         
         CheckForDuplicatePoolNames();
         
         CreatePools();
         
     }
     
     private void CheckForDuplicatePoolNames() {
         
         for (int index = 0; index < poolInfo.Length; index++) {
             string poolName= poolInfo[index].poolName;
             if(poolName.Length == 0) {
                 Debug.LogError(string.Format("Pool {0} does not have a name!",index));
             }
             for (int internalIndex = index + 1; internalIndex < poolInfo.Length; internalIndex++) {
                 if(poolName == poolInfo[internalIndex].poolName) {
                     Debug.LogError(string.Format("Pool {0} & {1} have the same name. Assign different names.", index, internalIndex));
                 }
             }
         }
     }
     
     private void CreatePools() {
         
         foreach(PoolInfo currentPoolInfo in poolInfo){
             
             Pool pool = new Pool();
             pool.canGrowPoolSize = currentPoolInfo.canGrowPoolSize;
             
             for(int index = 0; index < currentPoolInfo.poolSize; index++) {
                 //instantiate
                 GameObject go = Instantiate(currentPoolInfo.prefab) as GameObject;
                 PoolObject poolObject = go.GetComponent<PoolObject>();
                 if(poolObject == null) {
                     Debug.LogError("Prefab must have PoolObject script attached!: " + currentPoolInfo.poolName);
                 } else {
                     //set state
                     poolObject.ReturnToPool();
                     //add to pool
                     pool.Add(poolObject);
                 }
             }
             
             Debug.Log("Adding pool for: " + currentPoolInfo.poolName);
             poolDictionary[currentPoolInfo.poolName] = pool;
             
         }
     }
     
     public PoolObject GetObjectFromPool ( string poolName  ){
         PoolObject poolObject = null;
         
         if(poolDictionary.ContainsKey(poolName)) {
             Pool pool = poolDictionary[poolName];
             
             //get the available object
             for (int index = 0; index < pool.Count(); index++) {
                 PoolObject currentObject = pool.ObjectAt(index);
                 
                 if(currentObject.AvailableForReuse()) {
                     //found an available object in pool
                     poolObject = currentObject;
                     break;
                 }
             }
             
             
             if(poolObject == null) {
                 if(pool.canGrowPoolSize) {
                     Debug.Log("Increasing pool size by 1: " + poolName);
                     
                     foreach (PoolInfo currentPoolInfo in poolInfo) {    
                         
                         if(poolName == currentPoolInfo.poolName) {
                             
                             GameObject go = Instantiate(currentPoolInfo.prefab) as GameObject;
                             poolObject = go.GetComponent<PoolObject>();
                             //set state
                             poolObject.ReturnToPool();
                             //add to pool
                             pool.Add(poolObject);
                             
                             break;
                             
                         }
                     }
                 } else {
                     Debug.LogWarning("No object available in pool. Consider setting canGrowPoolSize to true.: " + poolName);
                 }
             }
             
         } else {
             Debug.LogError("Invalid pool name specified: " + poolName);
         }
         
         return poolObject;
     }
     
 }

For my public variables, I get the warning posted in the question topic: Field is never assigned to and will always have its default value. Changing the PoolInfo class from private to public fixes those warnings but the JS script has this class as private class PoolInfo extends System.Object {. Does JS treat private and public classes differently than C#?

For line 37 I get the warning: "Field 'EasyObjectPool.poolInfo' is never assigned to, and will always have its default value 'null'" and I don't know how to fix that. Any advice?
