List添加值、取值

public static List<object> GData = new List<object>();
 
//增加值
(new
        {
            Date = (),
            Name = ,
            NameId = ,
            Price = ,
            Memo = 
        });

//获取值
for (int i = 0; i < ; i++)
        {
            string DateVal = GData[i].GetType().GetProperty("Date").GetValue(GData[i], null).ToString();
            string NameVal = GData[i].GetType().GetProperty("Name").GetValue(GData[i], null).ToString();
            string NameIDVal = GData[i].GetType().GetProperty("NameId").GetValue(GData[i], null).ToString();
            string PriceVal = GData[i].GetType().GetProperty("Price").GetValue(GData[i], null).ToString();
            string MemoVal = GData[i].GetType().GetProperty("Memo").GetValue(GData[i], null).ToString();
        }
