Filter records from database using Where function in Linq using C# in ASP.Net MVC

How to select query on table via a function

I tried this syntax but it does not work.

I would like to know the correct syntax

public ActionResult GetName(string name)
{
    if (!string.IsNullOrWhiteSpace(name))
    {                
        List<Models.table> resultats = db.table.Where(table => db.table.Nom_de_site == name).ToList();
        return Json(resultats, JsonRequestBehavior.AllowGet);
    }
    return null;
}
