c# error in the official documentation

Unity Engine
1

See here, c# code version :

      i = 0;

should be

  int i = 0;

 CombineInstance[] combine = new CombineInstance[meshFilters.length];

should be

 CombineInstance[] combine = new CombineInstance[meshFilters.Length];

   while (i < meshFilters.length) {

should be

   while (i < meshFilters.Length) {

and still having errors :

Type `UnityEngine.Component' does not contain a definition for `sharedMesh' and no extension method `sharedMesh' of type `UnityEngine.Component' could be found (are you missing a using directive or an assembly reference?)

Please replace the wrong c# code from the documentation by :

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(MeshFilter))]
[RequireComponent(typeof(MeshRenderer))]

public class example : MonoBehaviour 
{
    void Start() 
	{
        MeshFilter[] meshFilters = GetComponentsInChildren<MeshFilter>();
        CombineInstance[] combine = new CombineInstance[meshFilters.Length];
        int i = 0;
		
        while (i < meshFilters.Length) 
		{
            combine[i].mesh = meshFilters[i].mesh;
            combine[i].transform = meshFilters[i].transform.localToWorldMatrix;
            meshFilters[i].gameObject.active = false;
            i++;
        }
		
        transform.GetComponent<MeshFilter>().mesh = new Mesh();
        transform.GetComponent<MeshFilter>().mesh.CombineMeshes(combine);
        transform.gameObject.active = true;
    }
}
