1、xmal文件中添加  DisplayMemberPath、SelectedValuePath属性

<ComboBox Name="MeaType" RenderTransformOrigin="1.72,2.273" Canvas.Left="48" Canvas.Top="226" Width="110" DisplayMemberPath="Name" SelectedValuePath="ID" SelectionChanged="MeaType_SelectionChanged" Loaded="MeaType_Loaded"> </ComboBox>

2、控件绑定的内容类

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

3.代码中添加需要绑定的数据

                List<MeaType> list = new List<MeaType>();
                list.Add(new MeaType { ID = 1,Name = "S11" });
                list.Add(new MeaType { ID = 2, Name = "S21" });
                list.Add(new MeaType { ID = 3, Name = "S12" });
                list.Add(new MeaType { ID = 4, Name = "S22" });
                MeaType.ItemsSource = list;  

4、代码中更改绑定
