c# - 从 DataSet 将组件数据绑定到表

Question

我创建了一个将组件与数据源中的表进行数据绑定的方法。：

private void AddDataBinding()
    {
        txtID.DataBindings.Add("Text", ds, "Ticket.RaffleID");
        cboName.DataBindings.Add("Value", ds, "Ticket.CustomerID");
        dtpDate.DataBindings.Add("Value", ds, "Ticket.Date");
        txtStore.DataBindings.Add("Text", ds, "Ticket.Store");
        txtAmount.DataBindings.Add("Text", ds, "Ticket.Amount");
        txtStub.DataBindings.Add("Text", ds, "Ticket.NoStub");

        cm = (CurrencyManager)this.BindingContext[ds, "Ticket"];
    }

private void frmCustomerTicket_Load(object sender, EventArgs e)
    {
        OpenConnection();
        AddDataBinding();
    }

当我运行代码时，出现了这条消息：“无法创建字段 Ticket 的子列表。”
