How to create mesh collider for line renderer ?

Hi all, I have a 2D project and I want to build a mesh renderer for line renderer in a game object by C# script but I dont know how to do. Please help! Any commend is much appriciated. using UnityEngine; using System.Collections; using System.Collections.Generic;

public class DrawLineCollider : MonoBehaviour {

 LineRenderer line;
 bool mousePressed;
 List<Vector3> points;
 Vector3[] pointsMesh;
 Vector3 mousePos, endPoint;
 MeshCollider mc;
     
 // Use this for initialization
 void Start () {
     line = gameObject.AddComponent<LineRenderer> ();
     line.SetVertexCount(0);
     line.SetWidth(0.1f, 0.1f);

     mousePressed = false;
     points = new List<Vector3>();

     gameObject.AddComponent<MeshFilter>();
     mc = gameObject.AddComponent<MeshCollider>();
 }
 
 // Update is called once per frame
 void Update () {
     if(Input.GetMouseButtonDown(0)){
         mousePressed = true;
         line.SetVertexCount(0);
         //Clear all points
         points.Clear();
         //Save startpoint
         Vector3 startPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         startPoint.z = 0;
     }
     
     if(mousePressed){
         mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         mousePos.z = 0;
         if(!points.Contains(mousePos)){
             points.Add(mousePos);
             line.SetVertexCount(points.Count);
             line.SetPosition(points.Count-1, points[points.Count-1]);
         }
         //Convert list point of linerenderer to array for vertice of mesh
     }
     
     if(Input.GetMouseButtonUp(0)){
         mousePressed = false;
         //Save endpoint
         endPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         endPoint.z = 0;
         line.SetPosition(points.Count-1,points[0]);
         //createLineCollider();
     }
 }
