我无法清除ListBox.SelectedItems集合.请说明我做错了什么.我以不同的方式清除收藏,但它留下以前的收藏.

我清楚收集所以:

chListBox.SelectedItems.Clear();

要么

chListBox.UnselectAll();

要么

chListBox.SetSelectedItems(new ArrayList());

我的代码:

public class CheckListBox : ListBox
    {
        public CheckListBox()
        {
            this.SelectionChanged += CheckListBox_SelectionChanged;
            this.Resources = Application.LoadComponent(new Uri("/TASWpfControls;component/Resources/CheckListBoxResources.xaml", UriKind.RelativeOrAbsolute)) as ResourceDictionary;
            this.ItemContainerStyle = this.Resources["CheckListBoxItem"] as Style;
            this.AddHandler(ButtonBase.ClickEvent, new RoutedEventHandler(ClickEventHandler));
        }

        private void ClickEventHandler(object sender, RoutedEventArgs routedEventArgs)
        {
            RoutedEventArgs eventArgs = new RoutedEventArgs(ItemSelectedEvent);
            this.RaiseEvent(eventArgs);
        }

        public string PropertyName { get; set; }

        public string PropertyCompare { get; set; }

        public static readonly DependencyProperty SelectedSourceProperty =
            DependencyProperty.Register("SelectedSource", typeof(IList), typeof(CheckListBox), new PropertyMetadata(SelectedSourceChanged));

        public IList SelectedSource
        { …

我正在尝试使用 KafkaTool 连接到 Kafka。我收到一个错误：连接到集群时出错。未能创建新的 KafkaAdminClient

Kafka 和 Zookeeper 托管在 Docker 中。我运行下一个命令

   docker network create kafka
   docker run --network=kafka -d --name zookeeper -e ZOOKEEPER_CLIENT_PORT=2181 confluentinc/cp-zookeeper:latest
   docker run --network=kafka -d -p 9092:9092 --name kafka -e KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092 -e KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1 confluentinc/cp-kafka:latest

KafkaTool 的设置

为什么 KafkaTool 无法连接到托管在 Docker 中的 Kafka？
