推荐答案

在 PowerShell 中，所有 if-statements 都需要大括号来包围它们的主体.下面是一个演示:

In PowerShell, all if-statements need braces to enclose their bodies. Below is a demonstration:

PS > if ($true) write 'true'
At line:1 char:10
+ if ($true) write 'true'
+          ~
Missing statement block after if ( condition ).
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : MissingStatementBlock

PS > if ($true) { write 'true' }
true
PS >

因此，您脚本的 if 语句部分应如下所示:

Therefore, the if-statement section of your script should look like this:

...
    if (Test-Connection -ComputerName $strComputer -Count 1 -Quiet)
    {
        $ExcelCell.Cells.Item($introw, 2) = "Online"

        $ExcelCell.Cells.Item($intRow, 1) = $strComputer.ToUpper() 
        $ExcelCell.Cells.Item($intRow, 3) = $objDisk.DeviceID 
        $ExcelCell.Cells.Item($intRow, 4) = "{0:N0}" -f ($objDisk.Size/1GB) 
        $ExcelCell.Cells.Item($intRow, 5) = "{0:N0}" -f ($objDisk.FreeSpace/1GB) 
        $ExcelCell.Cells.Item($intRow, 6) = "{0:P0}" -f ([double]$objDisk.FreeSpace/[double]$objDisk.Size) 
        $ExcelCell.cells.item($introw, 7) = "{0:N0}" -f ([double]$objDisk.Size/1GB - [double]$objDisk.Freespace/1GB)
    }

    else
    {
        $ExcelCell.Cells.Item($intRow, 1) = $strComputer.ToUpper() 
        $ExcelCell.Cells.Item($intRow, 2) = "Offline"
        $ExcelCell.Cells.Item($intRow, 3) = "x"
        $ExcelCell.Cells.Item($intRow, 4) = "x"
        $ExcelCell.Cells.Item($intRow, 5) = "x"
        $ExcelCell.Cells.Item($intRow, 6) = "x"
        $ExcelCell.cells.item($introw, 7) = "x"
    }
...
