c＃WPF从绑定到类对象的List <>获取值

Question

How to get value from a list that is binded to a class object? I have a class and a List of that class. im adding to list like this

private void loadAccountBalance(string total, string amount, string transaction, string date)
    {
        accountBalance_lst.Add(new accountBalanace_cls()
        {
            accountBalanceTotal = total,
            accountBalanceAmount = amount,
            accountBalanceTransaction = transaction,
            accountBalanceDate = date
        });
        accountsBalance_grd.Items.Refresh();
    }

this is my class

     public class accountBalanace_cls
    {
        public string accountBalanceTotal { get; set; }
        public string accountBalanceAmount { get; set; }
        public string accountBalanceTransaction { get; set; }
        public string accountBalanceDate { get; set; }
    }

and this is my declaration of List

      List<object> accountBalance_lst = new List<object>();

What I want to do is something like this I hope you'll understand what i'm trying to accomplish here

      int total = accountBalance_lst[1].AccountBalanceTotal;

Answer 1

The accountBalance_lst is of type List<object> it doesn't contains definition for AccountBalanceTotal . if doesn't have any specific reason for List<object> then make it as List<accountBalanace_cls> instead. Or else you can do some casting like the following:

  int total = ((accountBalanace_cls)accountBalance_lst[1]).AccountBalanceTotal;

Answer 2

Not sure I fully understand your question, but instead of doing this:

List<object> accountBalance_lst = new List<object>();

Why not do this:

var accountBalance_lst = new List<accountBalance_cls>();

So that you can do you can use the list objects like you wanted:

int total = accountBalance_lst[1].AccountBalanceTotal;
