Powershell缺失语句块后if

标签: powershell syntax-error

我有以下代码。但是在某处遗漏了{[()]}。我找不到它。 我在'if部分。但我不知道为什么它不起作用 如果有人可以提供小费或其他东西,那么它就会被创造出来。

感谢阅读。

在PowerShell中,所有if-statements都需要括号来包围它们的主体。以下是演示:

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,脚本的if语句部分应如下所示:

...
    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"
    }
...

您只使用一个 if 语句。 if 的语法如下:

***IF (condition returns true) { action }***

基本上,条件用圆括号表示,而执行块用大括号括起来。

一个简单的例子:

if (1 -eq 1) { Write-host "1 is equal to 1" }

当然,在上面的例子中,条件总是如此。只要返回布尔值(true或false),就可以使用任何条件。

在您的脚本中,在

if (Test-Connection -ComputerName $strComputer -Count 1 -Quiet) 

缺少大括号。你应该在'之后打开括号。 )'在'之前关闭'。之后,请记住将大括号放在' else'相应的声明。
