Just create a new list for each polygon, or convert the list to an array:

polygon = new OnlineMapsDrawingPoly(Polygon_LatLong.ToArray(), Color.blue, 2, new Color(1, 1, 1, 0.3f));

Thanks for replay

I have got your point ,but I need more clearance
your main should be make every polygon one array like this

public OnlineMaps map; //
public Texture2D markerTexture;
public List markers = new List();//
public OnlineMapsDrawingPoly polygon;//
public List Polygon_S = new List();

public List Polygon_LatLong;
public List Polygon_LatLong2;

Polygon_LatLong.Add(new Vector2(58.23256f, 23.59701f));
Polygon_LatLong.Add(new Vector2(58.23246f, 23.59685f));
Polygon_LatLong.Add(new Vector2(58.23221f, 23.59699f));
Polygon_LatLong.Add(new Vector2(58.23231f, 23.59715f));

OnlineMaps api = OnlineMaps.instance;
polygon = new OnlineMapsDrawingPoly(Polygon_LatLong, Color.blue, 2, new Color(1, 1, 1, 0.3f));
OnlineMapsDrawingElementManager.AddItem(polygon);

Polygon_LatLong2.Clear();
Polygon_LatLong2.Add(new Vector2(58.2326f, 23.59728f));
Polygon_LatLong2.Add(new Vector2(58.2326f, 23.59707f));
Polygon_LatLong2.Add(new Vector2(58.23256f, 23.59701f));
Polygon_LatLong2.Add(new Vector2(58.23231f, 23.59715f));
Polygon_LatLong2.Add(new Vector2(58.23231f, 23.59728f));

polygon = new OnlineMapsDrawingPoly(Polygon_LatLong2, Color.red, 2, new Color(1, 1, 1, 0.3f));
OnlineMapsDrawingElementManager.AddItem(polygon);

but if I have 1000 polygons how to deal with that
I try make list in list but only draw only one Polygon

Hello.

The polygon and line store reference to original IEnumerable (in this case, the list) that you passed them.
You reuse the list, so you have two polygon with the same points, because both polygons refer to the same list.

I am using Unity application I try to Draw multi polygon but only show last poly in array
This is my code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MPolygon : MonoBehaviour
{

public OnlineMaps map; //
public Texture2D markerTexture;
public List markers = new List();//
public OnlineMapsDrawingPoly polygon;//
public List Polygon_S = new List();

public List Polygon_LatLong;

// Start is called before the first frame update
void Start()
{

Vector2 cursorCoords;
// Frist Poly
Polygon_LatLong.Clear();
Polygon_LatLong.Add(new Vector2(58.23256f, 23.59701f));
Polygon_LatLong.Add(new Vector2(58.23246f, 23.59685f));
Polygon_LatLong.Add(new Vector2(58.23221f, 23.59699f));
Polygon_LatLong.Add(new Vector2(58.23231f, 23.59715f));

polygon = new OnlineMapsDrawingPoly(Polygon_LatLong, Color.blue, 2, new Color(1, 1, 1, 0.3f));
OnlineMapsDrawingElementManager.AddItem(polygon);
//Polygon_S.Add(polygon);
//OnlineMapsDrawingElementManager.AddItems(Polygon_S);

///'''''''''''''''''''''''''''''''''''''''''''''''''''''''''
///Second Poly
Polygon_LatLong.Clear();
Polygon_LatLong.Add(new Vector2(58.2326f, 23.59728f));
Polygon_LatLong.Add(new Vector2(58.2326f, 23.59707f));
Polygon_LatLong.Add(new Vector2(58.23256f, 23.59701f));
Polygon_LatLong.Add(new Vector2(58.23231f, 23.59715f));
Polygon_LatLong.Add(new Vector2(58.23231f, 23.59728f));

polygon = new OnlineMapsDrawingPoly(Polygon_LatLong, Color.red, 2, new Color(1, 1, 1, 0.3f));
OnlineMapsDrawingElementManager.AddItem(polygon);
//Polygon_S.Add(polygon);
// //OnlineMapsDrawingElementManager.AddItems(Polygon_S);

Vector2 center = new Vector2(58.2326f, 23.59728f);
int zoom = 10;
OnlineMaps.instance.position = center;
OnlineMaps.instance.zoom = zoom;
}

My code is file attched

Please I need help Guys
