var results = (from row in data.Tables[0].AsEnumerable()
               select new { 
                    Id = row.Field<int>("id"),Name = row.Field<string>("Name
               }).Distinct();

myComboBox.ValueMember = "Id";
myComboBox.DisplayMember = "Name";

foreach (var n in results)
{
    myComboBox.Items.Add(n);
}

然后,在ComboBox的SelectedIndexChanged方法中,我想检索所选项的Id,但是我无法访问“Id”属性,在myComboBox.SelectedItem中是所选对象.

private void myComboBox_SelectedIndexChanged(object sender,EventArgs e)
{
    if (myComboBox.SelectedItem != null)
    {
        var x = myComboBox.SelectedItem;

            ¿¿¿ ???
    }  
}

有任何想法吗？
