foreach循环不创建多维数组

Question

我有一个获取数据库列表的函数，并允许用户选择他们想要使用的数据库，需要将数组制作成多维数组，因为我需要一个针对数据库名称的文件路径。 / p>

以下是代码：

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foreach块中的else循环工作正常，当我在函数调用后将其打印出来时，我同时获得数据库名称和文件路径。 if块中的一个（if块的末尾）没有，它只打印出数据库的名称。
