WPF和winform区别 combobox 填充list例子

区别：

var deviceEnum = new MMDeviceEnumerator();
var devices = deviceEnum.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active).ToList();
combDevice.ItemsSource = devices;//wpf

combDevice.DataSource = devices;//WINFORM

------

comboBox1.DataSource = bindingSource1.DataSource;//WINFORM

生成ComboBox list代码例子：

List<string> list = new List<string>();
 BindingSource bsource=new BindingSource();

 //Set list dataSource
 bsource.DataSource = list;
 comboBox1.DataSource = bsource;

 //Now add an element via Binding object
 bsource.Add("One");
 bsource.Add("Two");

代码例子2：

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";

 

Or you may try ArrayList.Adapter method that creates Adapter wrapper of IList.

ArrayList items;

items=ArrayList.Adapter(comboBox1.Items);
items.Add("one");

代码：

  void Form1Load(object sender, EventArgs e)
        {
            List<string> myitems = new List<string>
            {
                "Item 1",
                "Item 2",
                "Item 3"
            };

            ComboBox box = new ComboBox();
            box.Bounds = new Rectangle(10, 10, 100, 50);
            source1.DataSource = myitems;
            box.DataSource = source1;

            ComboBox box2 = new ComboBox();
            box2.Bounds = new Rectangle(10, 80, 100, 50);
            source2.DataSource = myitems;
            box2.DataSource = source2;

            Controls.Add(box);
            Controls.Add(box2);
        }
