Question

与主题标题一样。我的数据库包含大量辅助表。想要构建一个下拉列表来选择我要加载内容的表。此代码...不起作用：

public ListEcoles()
{
    InitializeComponent();
    List<string> listEcoles = MainWindow._RE.ListEcoles();
    foreach (string nomEcole in listEcoles)
        listEcole.Links.Add(new Link() { DisplayName = nomEcole, Source = new Uri("/Controles/EcoleControl.xaml", UriKind.Relative) });
    listEcole.PreviewMouseLeftButtonUp += ListEcole_MouseLeftButtonUp;
}

private void ListEcole_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    ListBoxItem lbi = e.OriginalSource as ListBoxItem;
    if (lbi == null)
    {
        lbi = FindParent<ListBoxItem>(e.OriginalSource as DependencyObject);
    }

    if (lbi != null)
    {
        Link selectedLink = lbi.DataContext as Link;
        if (selectedLink != null)
        {
            string selectedDisplayName = selectedLink.DisplayName;
            MessageBox.Show(selectedDisplayName);
        }
    }
}

private static T FindParent<T>(DependencyObject dependencyObject) where T : DependencyObject
{
    var parent = VisualTreeHelper.GetParent(dependencyObject);

    if (parent == null) return null;

    var parentT = parent as T;
    return parentT ?? FindParent<T>(parent);
}

在mysql中，您可以访问information_schema过滤您的数据库名称

 SELECT table_name 
 FROM INFORMATION_SCHEMA.TABLES
 WHERE table_schema = 'your_db_name'
 and table_name LIKE 'Mytable_%'
 and table_type = 'BASE TABLE';

如何获取具有所选前缀的数据库中所有表的列表？
