组合框数据绑定引起的ArgumentException [英] ComboBox DataBinding causes ArgumentException

问题描述

结果
我几类对象：

I several objects of class:

class Person
{
    public string Name { get; set; }
    public string Sex { get; set; }
    public int Age { get; set; }

    public override string ToString()
    {
        return Name + "; " + Sex + "; " + Age;
    }
}

和具有类型的属性<一类code>人：

class Cl
{
    public Person Person { get; set; }
}

和我要绑定 Cl.Person 来组合框。当我尝试做这样的：

And I want to bind Cl.Person to combobox. When I try to do it like this:

Cl cl = new cl();
comboBox.DataSource = new List<Person> {new Person{Name = "1"}, new Person{Name = "2"}};
comboBox.DataBindings.Add("Item", cl, "Person");

我得到一个的ArgumentException 。我应该如何修改我的结合来获得正确的程序的行为吗？结果
提前感谢！

I get an ArgumentException. How should I modify my binding to get the correct program behavior?
Thanks in advance!

推荐答案

绑定为的SelectedItem：

Bind to "SelectedItem":

        var persons = new List<Person> { new Person() { Name = "John Doe"}, new Person() { Name = "Scott Tiger" }};
        comboBox1.DisplayMember = "Name";
        comboBox1.DataSource = persons;
        comboBox1.DataBindings.Add("SelectedItem", cl, "Person");
