                    tblBooking booking = datacontext.tblBookings.SingleOrDefault(x => x.BookingID == id);
                    tblVenue venue = datacontext.tblVenues.SingleOrDefault(x => x.VenueID == booking.Venue);
                    List<tblCustomer> customers = new List<tblCustomer>();
                    List<tblBookingGuest> guests = booking.tblBookingGuests.ToList();

                        foreach (tblBookingGuest guest in guests)
                        {

                            customers.Add(newcust);
                        }
                        int count = customers.Count;
                        CustFirstName.Text = Convert.ToString(customers);

推荐答案

您是要在客户列表上使用ToString()还是仅仅是伪代码?

Are you trying to use a ToString() on the customers List, or is that just meant to be pseudocode?

尝试使用类似于以下内容的内容:将列表转换为字符串在C#中

Try using something similar to this: Convert a list to a string in C#

这可能包括给tblCustomer类一个ToString()覆盖，然后使用它为文本框提供所需的字符串:

This will probably include giving the tblCustomer class a ToString() override, then use that to provide the strings you need to your text boxes:

class tblCustomer
{
    public override string ToString()
    {
        return this.name;
    }
}
