我有以下代码:

$DatabaseSettings = @();
$NewDatabaseSetting = "" | select DatabaseName, DataFile, LogFile, LiveBackupPath;
$NewDatabaseSetting.DatabaseName = "LiveEmployees_PD";
$NewDatabaseSetting.DataFile = "LiveEmployees_PD_Data";
$NewDatabaseSetting.LogFile = "LiveEmployees_PD_Log";
$NewDatabaseSetting.LiveBackupPath = '\\LiveServer\LiveEmployeesBackups';
$DatabaseSettings += $NewDatabaseSetting;

当我尝试使用字符串执行命令中的一个属性时:

& "$SQlBackupExePath\SQLBackupC.exe" -I $InstanceName -SQL `
  "RESTORE DATABASE $DatabaseSettings[0].DatabaseName FROM DISK = '$tempPath\$LatestFullBackupFile' WITH NORECOVERY, REPLACE, MOVE '$DataFileName' TO '$DataFilegroupFolder\$DataFileName.mdf', MOVE '$LogFileName' TO '$LogFilegroupFolder\$LogFileName.ldf'"

它试图只使用值$DatabaseSettings而不是值$DatabaseSettings[0].DatabaseName,这是无效的.
我的解决方法是将其复制到一个新变量中.

如何直接在双引号字符串中访问对象的属性？

我有以下代码:

$srv_range = 29..30+40+50..52
$srv_range.GetType()
$NewVMTemplate = New-Object psobject
$NewVMTemplate | Add-Member -MemberType NoteProperty -Name Name -Value $null

$srv_range | % {
    $pod= $_
    $servers = @()
    1..2 | % {
        $server = $NewVMTemplate | Select-Object *
        $server.Name = "pod" + "{0:D2}" -f $pod + "-srv" + $_
        $servers += $server
    }
    ForEach ( $server in $servers) {
        write-host $server.Name
    }
} 

输出:
