注意以下四个代码  
   xmlns:src="clr-namespace:SilverlightApplication1"

   <UserControl.Resources>
        <src:SexProvider x:Key="sexProvider"/>
    </UserControl.Resources>

   <ComboBox SelectedItem="{Binding Sex, Mode=TwoWay}" ItemsSource="{Binding SexList,Source={StaticResource sexProvider}}">                              
  
    public class SexProvider
    {
        public List<string> SexList
        {
            get
            {
                return new List<string> { "男", "女"};
            }
        }
    }
