Powershell参数错误

Question

因此，我试图将文件目录传递给底部的convert函数。 运行脚本时，我收到输出：

更迭

C：\\ test 2 \\ 00000027627-00001 \\处理清单

convert：无效参数-2 \\ 00000027627-00001 \\ C：\\ Users \\ pmanca \\ Desktop \\ msbxmlreader.ps1：35 char：13 + convert（[string] $ hostdirectoryPlusLoanPlusDocType）+ ~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + CategoryInfo：未指定：（无效的参数.. .0001 \\ PROCESSING：String）[]，RemoteException + FullyQualifiedErrorId：NativeCommandError

在C：\\ test之后，它似乎切断了文件路径。 文件路径可能太长吗？ 即使这样，我也无法想象在函数调用时出现错误，而在无法解析路径时出现在函数中的某个地方。

Answer 1

首先 ：在PowerShell中，当您调用函数时，一定不能使用括号：

convert $hostdirectoryPlusLoanPlusDocType 

或在评论中建议

convert -inputDirectory $hostdirectoryPlusLoanPlusDocType 

但不是 ：

convert([string]$hostdirectoryPlusLoanPlusDocType)

第二 ：应首先声明您的函数，然后再使用：

function toto ($var)
{
  Write-Host $var
}
toto "voila"

并不是

toto "voila"
function toto ($var)
{
  Write-Host $var
}
