问题描述

我想连接绑定源类对象的列表，然后对象的价值组合框任何人都可以提出如何做到这一点。

I want to connect a binding source to a list of class objects and then objects value to a combo box can anyone suggest how to do it

public class Country
    {
        public string Name { get; set; }
        public IList<City> Cities { get; set; }

        public Country()
        {
            Cities = new List<City>();
        }
    }

是我的班，我想它的名字字段绑定到可以用一个组合框，然后进行相关的绑定源

is my class and i want to bind its name field to a binding source which could be then associated with a combobox

推荐答案

你指的是一个组合框，我假设你不希望使用2路数据绑定（如果是这样，看看使用的BindingList ）

As you are referring to a combobox, I'm assuming you don't want to use 2-way databinding (if so, look at using a BindingList)

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

结果

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";
