Need help converting Java Array to C# Arrays

So basically im just trying to draw a line between some points, I have never used Array's and Im a little confused to weither c# even accepts them....

I get this error at the moment

Obviously im doing something wrong but i dont know what..

Tutorials, Example Code, General Comments any help welcome

Here is my code so far

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4.  
5. public class AIPath : MonoBehaviour {
6.  
7.     public Transform[] paths;
8.     public Color rayColor;
9.  
10.     void OnDrawGizmos()
11.     {
12.         Gizmos.color = rayColor;
13.         Transform[] paths_objs = transform.GetComponentInChildren<Transform>();
14.  
15.         foreach (Transform path_obj in paths_objs)
16.         {
17.             if(path_obj != gameObject.transform);
18.             {
19.                 paths[paths.Length] = path_obj;
20.             }
21.         }
22.  
23.         for (int i = 0; i < paths.Length; i++)
24.         {
25.             Vector3 pos = new Vector3(paths[i-1].position.x, paths[i-1].position.y, paths[i-1].position.z);
26.             if(i > 0)
27.             {
28.                 Vector3 prev = new Vector3(paths[i-1].position.x, paths[i-1].position.y, paths[i-1].position.z);
29.                 Gizmos.DrawLine(prev,pos);
30.             }
31.    
32.    
33.         }
34.     }
35.  
36. }
37.

Thanks for the reply and the info.

Thanks i got the arrays working but now its spamming the paths array, over and over.
How can I run the loop just once?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4.  
5. public class AIPath : MonoBehaviour {
6.  
7.     public List<Transform> paths = new List<Transform>();
8.     public Color rayColor;
9.     public List<Transform> paths_objs = new List<Transform>();
10.  
11.     void Start()
12.     {
13.         foreach (Transform trans in transform.GetComponentInChildren<Transform>())
14.         {
15.             paths_objs.Add(trans);
16.         }
17.     }
18.  
19.     void OnDrawGizmos()
20.     {
21.         Gizmos.color = rayColor;
22.  
23.  
24. // JUST NEED TO THIS RUN ONCE BUT IT SPAMS OVER AND OVER
25.         foreach (Transform path_obj in paths_objs)
26.         {
27.             if(path_obj != this.gameObject.transform);
28.             {
29.                 paths.Add(path_obj);
30.             }
31.         }
32.  
33.         for (int i = 0; i < paths.Count; i++)
34.         {
35.             Vector3 pos = new Vector3(paths[i].position.x, paths[i].position.y, paths[i].position.x);
36.             if(i > 0)
37.             {
38.                 Vector3 prev = new Vector3(paths[i-1].position.x, paths[i-1].position.y, paths[i-1].position.z);
39.                 Gizmos.DrawLine(prev,pos);
40.             }
41.  
42.  
43.         }
44.     }
45.  
46. }
47.  

*edit*
Durp I just moved the code into start and it fixed it.
