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";

我要显示什么"名称",但我希望"Id"是与选择相关联的值.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

你可以尝试这样.....

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......

您通常可以使用 ComboBoxItem.Tag 来完成此类操作。
