How to loop array of objects using forEach?

I want to display the fields of objects using forEach, but something is not working for me.It doesn’t show me the values ??that I entered, but only the type of Object

Transportation[] companys = new Transportation[2];
for (int i = 0; i <=companys.Length-1; i++)
{
    companys[i] = new Transportation();
    Console.WriteLine("Enter company: ");
    companys[i].Name = Console.ReadLine();
    Console.Write("Enter unit price: ");
    companys[i].Cost = Convert.ToDouble(Console.ReadLine());
    Console.Write("Weight: ");
    companys[i].Weight = Convert.ToDouble(Console.ReadLine());

}
Console.Clear();
foreach (Transportation key in companys)// here is problem
{
   Console.WriteLine("List "+companys[key]);
}
