如何将自定义对象列表绑定到ComboBox？

Question

如何将自定义对象列表绑定到组合框？这就是我目前所拥有的：

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

我是什么＆＃34;姓名＆＃34;要显示但我想要＆＃34; Id＆＃34;是与选择相关的值。你怎么在winforms中做到这一点？

这是Coarse obj：

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

...谢谢

Answer 1

你可以这样试试......

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";

我希望它会帮助你...

Answer 2

确定您的_viewModel.Coarses究竟是什么，但试试这个？

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

或只是

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

您通常可以将ComboBoxItem.Tag用于此类事情。
