绑定主要是通过设置静态数据源，然后设置绑定控件的DisplayMemberPath和SelectedValuePath

界面代码：

xmlns:c="clr-namespace:WPF1" >
<Page.Resources>
<c:EmPAll x:Key="empAll"></c:EmPAll>
<c:AllData x:Key="allData"></c:AllData>
</Page.Resources>
<Grid>
<ComboBox Height="23" ItemsSource="{ StaticResource empAll}" DisplayMemberPath="Name" SelectedValuePath="ID"  HorizontalAlignment="Left" Margin="47,37,0,0" Name="comboBox1" VerticalAlignment="Top" Width="120"/>
<ListBox Height="60" ItemsSource="{ StaticResource allData}" DisplayMemberPath="Name" SelectedValuePath="ID" HorizontalAlignment="Left" Margin="48,133,0,0" Name="listBox1" VerticalAlignment="Top" Width="167"/>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="197,25,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click"/>

</Grid>

后台代码：

namespace WPF1
{
///<summary>
/// 绑定Combox.xaml 的交互逻辑
///</summary>
    public partial class 绑定Combox : Page
    {
public 绑定Combox()
        {
            InitializeComponent();
        }

//获取选中的值
        private void button1_Click(object sender, RoutedEventArgs e)
        {
string val = comboBox1.SelectedValue.ToString();
var val2 = (listBox1.SelectedItem as Emp).Name;
            MessageBox.Show(val + "," + val2);
        }
    }

public class Emp
    {
public int ID { get; set; }
public string Name { get; set; }
    }

public class EmPAll : System.Collections.ObjectModel.ObservableCollection<Emp>
    {
public EmPAll()
        {
this.Add(new Emp { ID = 1, Name = "A" });
this.Add(new Emp { ID = 2, Name = "B" });
        }
    }

public class AllData : System.Collections.ObjectModel.ObservableCollection<Emp>
    {
public AllData()
        {
for (int i = 0; i < 10; i++)
            {
this.Add(new Emp { ID = i, Name = "Name" + i });
            }
        }
    }
}
