相关的事件处理器代码例如以下所看到的：


private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e)
{
    if (string.IsNullOrEmpty(this.NameTextBox.Text) == true) e.CanExecute = false;
    else e.CanExecute = true;
}

private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
    string name = this.NameTextBox.Text;
    if (e.Parameter.ToString() == "Teacher")
    {
        this.NewItemListBox.Items.Add(string.Format("New Teacher: {0}， 学而不厌，诲人不倦。", name));
    }
    else if (e.Parameter.ToString() == "Student")
    {
        this.NewItemListBox.Items.Add(string.Format("New Student: {0}，好好学习，天天向上。", name));
    }
}
