foreach循环未创建多维数组

Question

我有一个获取数据库列表并允许用户选择他们要使用的数据库的函数，该数组需要制作成多维数组，因为我需要针对数据库名称的文件路径。

这是代码：

function GetDBList {
    Param ($MoveAll)
    $ServerAddress = "."
    $DBList = Invoke-Sqlcmd -Query "SELECT name FROM   sys.databases WHERE  CASE WHEN state_desc = 'ONLINE'  THEN OBJECT_ID(QUOTENAME(name) + '.[dbo].[settings]', 'U') END IS NOT NULL" -ServerInstance $ServerAddress

    $databaseList = @()
    $databaseListDoc = @()
    $databaseListSelect = @()
    $databaseListFinal = @()

    for ($i = 0; $i -lt $dbList.count; $i++) {
        $databaseList += $dbList.ItemArray[$i]
    }

    # ----------------- EDIT ------------------------------------------------------
    # Gets the document path - Needs to be changed to account for multiple branches
    $i = 0

    # Beging database selection ----------------------
    if ($MoveAll -eq $false) {

    # Form creation removed 

        foreach ($item in $databaseList) {
            [void]$listBox.Items.Add($item)
        }

    # Form creation removed 

        if ($result -eq [System.Windows.Forms.DialogResult]::OK) {
            $databaseListSelect += $listBox.SelectedItems
        }

        foreach ($item in $databaseListSelect) {
            $DBPath = Invoke-Sqlcmd -Query "SELECT TOP 1 BDocumentsFolder FROM tblBranchSettings" -ServerInstance $ServerAddress -Database $item
            $path = $DBPath.ItemArray[0] -replace ('\Documents', "")

            $databaseListFinal += ,@($item, $path)
            $i++
        }
    } else {
        foreach ($item in $databaseList) {
            $DBPath = Invoke-Sqlcmd -Query "SELECT TOP 1 BDocumentsFolder FROM tblBranchSettings" -ServerInstance $ServerAddress -Database $item
            $path = $DBPath.ItemArray[0] -replace ('\Documents', "")

            $databaseListFinal += ,@($item, $path)
            $i++
        }
    }

    return , $databaseListFinal
}

底部的else块中的foreach循环工作正常，当我在函数调用后将其打印出来时，我同时获得了数据库名称和文件路径。 里面的一个if块（在结束if块）不，它只是打印出数据库的名称。
