powershell - 为什么我的PowerShell结果重复？

Question

美好的一天，

PowerShell新秀在这里...

如果我这样输出到屏幕:

    foreach($databasePermission in $database.EnumDatabasePermissions($user.Name))
{
    Write-Host $databasePermission.PermissionState $databasePermission.PermissionType "TO" $databasePermission.Grantee
} 

我得到了，这就是我想要的:

Grant CONNECT TO dbo

但是，如果我尝试输出到这样的文本文件:

    foreach($databasePermission in $database.EnumDatabasePermissions($user.Name))
{
    "$databasePermission.PermissionState $databasePermission.PermissionType TO $databasePermission.Grantee" | Out-File $filename
} 

我的结果重复如下:

[dbname] Database: cust_serv, Grant, CONNECT.PermissionState [dbname] Database: cust_serv, Grant, CONNECT.PermissionType TO [dbname] Database: cust_serv, Grant, CONNECT.Grantee

谢谢!

如果使用字符串访问对象的属性，则必须将其包含在$(...)中:

看一下两者之间的区别

"$databasePermission.PermissionState"

和

"$($databasePermission.PermissionState)"
