Why can't we declare var a = new List at class level?

Question

I know we cannot do this at class level but at method level we can always do this.

var myList=new List // or something else like this
<

Pass List Type in Generic

class Class1
{
    public void genmethod(T i,int Count)
    {


        List list = i as List;

        for (int j = 0; j < Count; j++)
        {
            Console.WriteLine(list[j]);
        }
    }
    static void Main(string[] args)
    {
        Class1 c = new Class1();
        c.genmethod("str",0);
        List l = new List();
        l.Add("a");
        l.Add("b");
        l.Add("c");
        l.Add("d");
        c.genmethod>(l,l.Count);

        Console.WriteLine("abc");
        Console.ReadLine();
    }
}
