尝试移动和项目或多个，如果从一个列表框中选择到另一个.左边的列表框中填充了从AD搜索的用户.然后我想选择一个或多个，并将它们移动到右边的列表框.我的问题是我不能移动它们.下面的代码是搜索和移动功能的功能.我是新的WPF，所以学习和发挥得到一些理解.希望有人能在这方面提供帮助.

function SearchDGUserClick
{
    param($sender, $e)

$DGMemberSearchListBox.ItemsSource

$query = $DGUserSearchText.Text
$UserSearch = (Get-ADUser -Filter "Name -like '*$query*'") | Select SamAccountName | Sort -Property SamaAccountName

$DGMemberSearchListBox.ItemsSource = $UserSearch

}

function AddUserClick
{
    param($sender, $e)

#$UserSearch should be an array or collection of user objects
$DGMemberSearchListBox.ItemsSource = $UserSearch

#Handle the button click or any other event that triggers the move
$selectedItems = @()

foreach ($item in $DGMemberSearchListBox.SelectedItems) {
    #If DGMemberAddListBox doesn't have the item yet, add it
    if ($DGMemberAddListBox.Items -notcontains $item) {
        $DGMemberAddListBox.Items.Add($item)
    }

    #Remove the item from DGMemberSearchListBox
    $selectedItems += $item
}

#Remove the selected items from DGMemberSearchListBox
foreach ($item in $selectedItems) {
    $DGMemberSearchListBox.Items.Remove($item)
}

}
