wpf ComboBox控件DisplayMemberPath属性怎么绑定多值？从数据库绑定

Question

怎么在ComboBox控件上显示两个值，就是把name、id都显示出来

Answer 1

ds = new DataSet();
DBHelper dbHelper = new DBHelper();
// 查询歌曲类型的Sql语句
string sql = "select * from song_type";
SqlDataAdapter adapter = new SqlDataAdapter(sql, dbHelper.Connection);
adapter.Fill(ds, "song_type");

// 绑定歌曲类型到下拉列表中
this.cboSongType.DataSource = ds.Tables["song_type"];
this.cboSongType.ValueMember = "songtype_id";
this.cboSongType.DisplayMember = "songtype_name";
