要复制的行的索引超出范围

从我的代码开始，然后解释问题。

 var customerAddresses = new CustDeliveryAddresses();
        // Select Columns
        customerAddresses.Query.Columns.Add(new Column(CustDeliveryAddress.FIELD_DESCRIPTION));
        customerAddresses.Query.Columns.Add(new Column(CustDeliveryAddress.FIELD_POSTCODE));
        // Filter by Customer.
        customerAddresses.Query.Filters.Add(new Filter(CustDeliveryAddress.FIELD_CUSTOMERDBKEY, customerLookup.Customer.SLCustomerAccount));
        // Find
        customerAddresses.Find();

        var addresses = from CustDeliveryAddress address in customerAddresses
                        select new
                        {
                            address.Description,
                            address.PostCode
                        };
        //customerDeliveryAddesses.AutoGenerateColumns = false;
        customerDeliveryAddesses.DataSource = addresses.ToList();

所以，当地址。ToList（） 被分配给 DataGridView 的 DataSource 属性 （customerDeliveryAddresses） 我收到一个错误，指出"要复制的行的索引超出范围"，我无法找到原因。

请有人指出我正确的方向。
