如何將自定義對象列表綁定到ComboBox？

Question

如何將自定義對象列表綁定到組合框？ 這就是我目前所擁有的：

            this.classCmbo.DataSource = _viewModel.Coarses;
            this.classCmbo.DisplayMember = "Name";
            this.classCmbo.ValueMember = "Id";

我要顯示什么“名稱”，但我希望“Id”是與選擇相關聯的值。 你怎么在winforms中做到這一點？

這是Coarse obj：

 public class Coarse
    {
        public virtual int Id { get; private set; }
        public virtual string Name { get;  set; }
    }

謝謝...

Answer 1

你可以嘗試這樣.....

public class Country
{
    public string Name { get; set; }
    public IList<City> Cities { get; set; }
    public Country(string _name)
    {
        Cities = new List<City>();
        Name = _name;
    }
}

List<Country> countries = new List<Country> { new Country("UK"), 
                                     new Country("Australia"), 
                                     new Country("France") };

bindingSource1.DataSource = countries;

comboBox1.DataSource = bindingSource1.DataSource;

comboBox1.DisplayMember = "Name";
comboBox1.ValueMember = "Name";

我希望它會幫助你......

Answer 2

不確定你的_viewModel.Coarses究竟是什么，但試試這個？

this.classCmbo.DataSource = _viewModel.Coarses;
this.classCmbo.DisplayMember = _viewModel.Coarses.Name;
this.classCmbo.ValueMember = _viewModel.Coarses.Id;

要不就

this.classCmbo.DataSource = _viewModel.Coarses;
this.classCmbo.DisplayMember = Coarses.Name;
this.classCmbo.ValueMember = Coarses.Id;

您通常可以使用ComboBoxItem.Tag進行此類操作。
