c# - 如何将自定义对象列表绑定(bind)到 ComboBox？

Question

如何将自定义对象列表绑定(bind)到组合框？这是我目前拥有的:

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

我要显示什么“名称”，但我希望“Id”是与选择关联的值。你如何在 winforms 中做到这一点？

这是粗糙的对象:

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

谢谢...

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";

希望对你有帮助...
