C# 如何从选定的ListViewItems中获取名称？

我有一个与树视图数据绑定的ListView，树视图数据绑定到XmlDataProvider。在列表视图中，您可以一次选择多个项目。我的问题是我需要知道选择了哪些项目。如何从ListViewItems中获取名称

XAML：

将返回类型（很可能是ListViewItem）。如果该类型为XmlNode，则需要强制转换该类型

private void listViewCards_KeyDown(object sender, KeyEventArgs e)
{
    IList selectedListViewItems = listViewCards.SelectedItems;
    if (selectedListViewItems.Count > 1)
    {
        foreach(var node in ((ListViewItem)selectedListViewItems).Tag as XMLNode)
        {
            // Find your node in whatever type contains your xml
            // Do Some deleting or what have you.
        }
    }
}

类型的对象 “System.Windows.Controls.SelectedItemCollection” 无法转换为 “System.Windows.Controls.ListViewItem”

试试这个：

private void listViewCards_KeyDown(object sender, KeyEventArgs e)
{
     IList selectedListViewItems = listViewCards.SelectedItems;
     if (selectedListViewItems.Count > 1)
     {
         //delete all selected items from xml:
         var collection = selectedListViewItems.Cast<XmlNode>();  //assuming your underlying data is XmlNode
         foreach(XmlNode node in collection)
         {
             //do whatever you want to do with node
             if (node.InnerText.Equals( ??? ))
             {
                 //mark for deleting
             }
         }
     }
}

private void listViewCards\u KeyDown（对象发送方，KeyEventArgs e）
{
IList selectedListViewItems=listViewCards.SelectedItems；
如果（selectedListViewItems.Count>1）
{
//从xml中删除所有选定项：
var collection=selectedListViewItems.Cast（）；//假设基础数据是XmlNode
foreach（集合中的XmlNode节点）
{
//对节点执行任何您想执行的操作
if（node.InnerText.Equals（？？？））
{
//删除标记
}
}
}
}

类型为“System.Windows.Controls.SelectedItemCollection”的对象无法转换为“System.Windows.Controls.ListViewItem”的对象太棒了，我很接近了，一小时前我尝试了以下操作：foreach（selectedListViewItems.Cast（）中的对象节点）

listViewCards.SelectedItems;

private void listViewCards_KeyDown(object sender, KeyEventArgs e)
{
    IList selectedListViewItems = listViewCards.SelectedItems;
    if (selectedListViewItems.Count > 1)
    {
        foreach(var node in ((ListViewItem)selectedListViewItems).Tag as XMLNode)
        {
            // Find your node in whatever type contains your xml
            // Do Some deleting or what have you.
        }
    }
}

private void listViewCards_KeyDown(object sender, KeyEventArgs e)
{
     IList selectedListViewItems = listViewCards.SelectedItems;
     if (selectedListViewItems.Count > 1)
     {
         //delete all selected items from xml:
         var collection = selectedListViewItems.Cast<XmlNode>();  //assuming your underlying data is XmlNode
         foreach(XmlNode node in collection)
         {
             //do whatever you want to do with node
             if (node.InnerText.Equals( ??? ))
             {
                 //mark for deleting
             }
         }
     }
}
