  • 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:
     1 List<string> list = new List<string>();
     2  BindingSource bsource=new BindingSource();
     3 
     4  //Set list dataSource
     5  bsource.DataSource = list;
     6  comboBox1.DataSource = bsource;
     7 
     8  //Now add an element via Binding object
     9  bsource.Add("One");
    10  bsource.Add("Two");

    代码例子2:
     1 public class Country
     2 {
     3     public string Name { get; set; }
     4     public IList<City> Cities { get; set; }
     5     public Country(string _name)
     6     {
     7         Cities = new List<City>();
     8         Name = _name;
     9     }
    10 }
    11 
    12 
    13 
    14 List<Country> countries = new List<Country> { new Country("UK"), 
    15                                      new Country("Australia"), 
    16                                      new Country("France") };
    17 
    18 bindingSource1.DataSource = countries;
    19 
    20 comboBox1.DataSource = bindingSource1.DataSource;
    21 
    22 comboBox1.DisplayMember = "Name";
    23 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");


    其他
    ComboBox代码:
     1   void Form1Load(object sender, EventArgs e)
     2         {
     3             List<string> myitems = new List<string>
     4             {
     5                 "Item 1",
     6                 "Item 2",
     7                 "Item 3"
     8             };
     9 
    10             ComboBox box = new ComboBox();
    11             box.Bounds = new Rectangle(10, 10, 100, 50);
    12             source1.DataSource = myitems;
    13             box.DataSource = source1;
    14 
    15             ComboBox box2 = new ComboBox();
    16             box2.Bounds = new Rectangle(10, 80, 100, 50);
    17             source2.DataSource = myitems;
    18             box2.DataSource = source2;
    19 
    20             Controls.Add(box);
    21             Controls.Add(box2);
    22         }

    其他区别:

    private void btIATstop_Click(object sender, EventArgs e)

    private void btnStop_Click(object sender, RoutedEventArgs e) //WPF
