        public List<Address> lstaddress {get;set;}

    }


    public class Name
    {

        public string LName;
    }

    public class Address
    {
        public string address1 { get; set; }
        public string address2 { get; set; }
        public int pincode { get; set; }

    }

public  string  DisplayData()
     {
         try
         {
             Userinfo u = new Userinfo();
             Address a = new Address();
             Name N = new Name();
             List<Name> nn = new List<Name>();
             List<Address> aa = new List<Address>();


             a.address1 = "abc";
             a.address2 = "def";
             a.pincode = 000000;
             aa.Add(a);

             N.Fname = "test";
             N.LName = "data";

             nn.Add(N);
             u.lstaddress = aa;
             u.name = nn;

             string aaa= new JavaScriptSerializer().Serialize(u).ToString();







             return "True";
         }
         catch(Exception ex)
         {
             return "error";
         }
     }

sample String:-

{"name":[{"Fname":"test","LName":"data"}],"lstaddress":[{"address1":"abc","address2":"def","pincode":0}]}

Your string has two faults: "name" is incorrect, it should be "Name" as C# is case sensitive; and "lstaddress" should be "Address" to match the C# class:

{"Name":[{"Fname":"test","LName":"data"}],"Address":[{"address1":"abc","address2":"def","pincode":0}]}

Is correct and should deserialize OK to the C# classes you show.
