Powershell 在进行除法时从UInt64转换时出错？

我试图在远程计算机上使用win32_logicaldisk获取可用磁盘空间，但从UInt64转换时出错。我不知道为什么会失败。我还需要使用带逗号的数字分组格式化数字

# Find free disk space on another computer
$ConvertToGB = (1024 * 1024 * 1024)
$disk = get-WmiObject win32_logicaldisk -Computername "MyServerName" -Filter "DeviceID='D:'" | Select-Object $disk.FreeSpace
$space = $disk.FreeSpace / $ConvertToGB
Write-Output "{0:N}" -f $space

我得到的错误是：

> Select-Object : Cannot convert System.UInt64 to one of the following
> types {System.String, System.Management.Automation.ScriptBlock}. At
> line:14 char:91
> + ... viceID='D:'" | Select-Object $disk.FreeSpace

我一部分代码都不懂

$disk = get-WmiObject win32_logicaldisk -Computername "MyServerName" -Filter "DeviceID='D:'" | Select-Object $disk.FreeSpace

为什么指定

|如果在变量
$space
中指定after，请选择对象$disk.FreeSpace

$space = $disk.FreeSpace / $ConvertToGB

---

如果在没有

|的情况下运行代码，请选择对象$disk.FreeSpace

，任何操作都可以：

# Find free disk space on another computer
$ConvertToGB = (1024 * 1024 * 1024)
$disk = get-WmiObject win32_logicaldisk -Computername "MyServerName" -Filter "DeviceID='C:'"
$space = $disk.FreeSpace / $ConvertToGB
Write-Output "{0:N}" -f $space

祝您度过愉快的一天（：

|选择对象$disk.FreeSpace

->

|选择对象FreeSpace

或删除；

1024*1024*1024

->

1gb

）。
