嗨
为此:
1.在Windows窗体设计器中，转到组合框属性.
2.找到数据源属性并将其展开
3.单击添加新的项目数据源".
4.在向导中，选择对象"，然后选择下一步".
5.在树中选择Person类(如果没有，请尝试使用Person类构建项目).
6.单击完成(新组件将添加到名为personBindingSource的表单中)
7.找到组合框属性DisplayMember.
8.从属性列表中选择以显示(名称)或键入它.

9.在Form_Load中放置:

Hi
To Do this:
1. In Windows Forms designer go to combobox properties.
2. Find datasource property and expand it
3. Click "Add new Project datasource".
4. In the wizard select Object and then Next.
5. Select Person class in the tree ( if you does not have it try to build project with Person class ).
6. Click finish ( New component will be added to the form named personBindingSource )
7. Find combobox property DisplayMember.
8. Select from the list you property to display ( Name ) or type it.

9. In the Form_Load put:

personBindingSource.DataSource = person; // initialized list of your persons

就是这样.

Thats it.

尝试这种方式

Try this way

List<Person> person = new List<Person>()
            {
                new Person(){Name="Anna", Birthday=new DateTime(2006, 10, 01), Age=12},
                new Person(){Name="Ben", Birthday=new DateTime(2006, 11, 02), Age=13},
                new Person(){Name="Cora", Birthday=new DateTime(2006, 01, 03), Age=11},
                new Person(){Name="Dan", Birthday=new DateTime(2006, 02, 04), Age=11},
                new Person(){Name="Eve", Birthday=new DateTime(2006, 12, 20), Age=14},
                new Person(){Name="Fe", Birthday=new DateTime(2006, 12, 05), Age=15},
                new Person(){Name="George", Birthday=new DateTime(2006, 12, 06), Age=12},
                new Person(){Name="Helen", Birthday=new DateTime(2006, 12, 30), Age=13},
                new Person(){Name="Ivan", Birthday=new DateTime(2006, 12, 30), Age=15},
            };
            comboBox1.DataSource = person;
            comboBox1.DisplayMember = "Name";
