`selectedItems` 通常是一个数组或列表,用于存储用户在某个界面或控件中选择的项。例如,在一个多选列表框中,当用户选择了其中的某些项时,这些项的信息可以被存储在 `selectedItems` 中。在一个文件浏览器中,当用户选择了某些文件或文件夹时,这些文件或文件夹的路径信息也可以被存储在 `selectedItems` 中。`selectedItems` 通常被用于处理用户的选择操作,例如执行一些针对所选项的操作,或者将所选项作为参数传递给其他函数或组件。

SelectedItems
SelectedItems是ListBox控件中被选中的项的集合。如果SelectionMode属性设置为Single,那么SelectedItems只会包含一个项。如果SelectionMode属性设置为Multiple或Extended,SelectedItems则会包含多个项。在你提供的代码中,使用循环来删除被选中的项是正确的做法。
WPF SelectedItems
WPF (Windows Presentation Foundation) is a framework for building desktop applications in Windows. The SelectedItems property is commonly used in WPF for controls that support multiple item selection, such as ListBox, ListView, DataGrid, etc.
The SelectedItems property is a collection that stores the selected items from the control. It allows you to access and manipulate the selected items programmatically. Here's an example of how you can use the SelectedItems property:
```csharp
// Assuming you have a ListBox named "myListBox" in your XAML
// Access the selected items using the SelectedItems property
var selectedItems = myListBox.SelectedItems;
// You can iterate through the selected items
foreach (var item in selectedItems)
{
// Do something with each selected item
}
// You can also access individual selected items by index
var firstSelectedItem = myListBox.SelectedItems[0];
```
Keep in mind that the SelectedItems property returns a collection, so you may need to cast the items to the appropriate type based on your data model.
I hope this helps! Let me know if you have any further questions.
