在WPF中，使用JComboBox并具有SelectionChanged =＆＃34; myComboBox_SelectionChanged＆＃34; xaml中的字段，如何获取新所选项目的字符串？下面的代码显示以前所选项目的字符串。

private void myComboBox_SelectionChanged(object sender, SelectionChangedEventArgs args)
{
     var comboBox = (sender as ComboBox);
     Console.WriteLine(comboBox.Text);  //prints out PREVIOUSLY selected item
}

尝试事件args上的AddedItems属性。这将获得一个包含所选项目的列表：

    private void myComboBox_SelectionChanged(object sender, SelectionChangedEventArgs args)
    {
        IList items = args.AddedItems;
        object firstSelecteditem = items[0];
    }
