Upload level details, variable always null.

I'm having a bit of of a trouble with my code. I wanted to check if a certain variable of a certain type could be null if not initialized. I'm afraid in this case it's always null. can anyone help me?

 using UnityEngine;
 using System.Collections;
 
 public class AppManager : MonoBehaviour {
 
     public GameObject GameController_Obj;
     
     private GameController_V3 GameController_Script;
 
     SceneList LevelList= new SceneList();
 
     public LevelStruct Level_1=new LevelStruct();
 
     // Use this for initialization
     void Start () {
 
         Level_1=LevelList.LevelPick (1);
     
         GameController_Script = GameController_Obj.GetComponent<GameController_V3> ();
 
         
 //        GameController_Script.LevelDetails = Level_1;
         //GameController_Script.SetLVLDetailvs(Level_1);
         //GameController_Script.LevelDetails.CopyLevel (Level_1);
 
     }
     
     // Update is called once per frame
     void Update () {
 
         if (GameController_Script.LevelDetails==null) {
 
                 GameController_Script.LevelDetails = Level_1;
         }
     
     }
 }
 

the variable in question is "LevelDetails" of the type LevelStruct.

 using UnityEngine;
 using System.Collections;
 
 public class LevelStruct : MonoBehaviour {
 
     public string Name;
     public int Number;
     public int Lives;
 
     public CameraPosSctruct GameCameraPos;
     public CameraPosSctruct MenuCameraPos;
 
     public LevelStruct(){
         Name = "";
         Number = new int();
         Lives = new int();
 
         GameCameraPos = new CameraPosSctruct ();
         MenuCameraPos = new CameraPosSctruct ();
     }
 
     public LevelStruct(string Name_, int Number_, int Lives_, CameraPosSctruct GameCameraPos_,CameraPosSctruct MenuCameraPos_){
         Name = Name_;
         Number = Number_;
         Lives = Lives_;
         
         GameCameraPos = GameCameraPos_;
         MenuCameraPos = MenuCameraPos_;
     }
 
     public void CopyLevel(LevelStruct FromLVL){
         
         Name = FromLVL.Name;
         Number = FromLVL.Number;
         Lives = FromLVL.Lives;
         
         GameCameraPos = FromLVL.GameCameraPos;
         MenuCameraPos = FromLVL.MenuCameraPos;
     }
 }
 

I really would like your help.

And thank you in advance.

PS: And I would appreciate if anyone can suggest a better way to get rid of that warning about "new Keyword".
