Problem trying to convert a JS script to C#. The below JS has been converted to C#

JS

static function check_res(g:GameObject):float
{
    var map:_mapObject = g.GetComponent("_mapObject");
   
    var w2s = Camera().main.WorldToScreenPoint;        
    var m:MeshFilter = g.GetComponent(MeshFilter);     
    var mv:Vector3[] = m.mesh.vertices;    
    var t   = g.transform.position;    
    var d   = Vector3.Distance(w2s(mv[0]+t), w2s(mv[8]+t));
        d  += Vector3.Distance(w2s(mv[2]+t), w2s(mv[6]+t));
    return d;
}

C#

public static float check_res(GameObject g)
{
	_mapObject map= (_mapObject) g.GetComponent("_mapObject");

	Camera w2s = new Camera().main.WorldToScreenPoint;      
	
	MeshFilter m= (MeshFilter)g.GetComponent(typeof(MeshFilter));
	Vector3[] mv= m.mesh.vertices;
	var t   = g.transform.position;    
	var d   = Vector3.Distance(w2s(mv[0]+t), w2s(mv[8]+t));
	d  += Vector3.Distance(w2s(mv[2]+t), w2s(mv[6]+t));
	return d;
}

The issue is Static member UnityEngine.Camera.main’ cannot be accessed with an instance reference, qualify it with a type name instead`

I am partly guessing but is that what you want?

public static float check_res(GameObject g)
{
    MeshFilter m = (MeshFilter)g.GetComponent(typeof(MeshFilter));
    Vector3[] mv = m.mesh.vertices;
    var t = g.transform.position;
    var d = Vector3.Distance(Camera.main.WorldToScreenPoint(mv[0] + t), Camera.main.WorldToScreenPoint(mv[8] + t));
    d += Vector3.Distance(Camera.main.WorldToScreenPoint(mv[2] + t), Camera.main.WorldToScreenPoint(mv[6] + t));
    return d;
}
