Question

我有一个将从第三方应用程序动态生成的字符串

$somePath = "D:\some\path\name.of - my file [20_32_21].mp4"

我需要能够在函数中验证此路径。

$somePath = "D:\some\path\name.of - my file [20_32_21].mp4"

Function ValidatePath{
    Param($path)
    if(Test-Path $path){
        Write-Host "Worked"
    } else {
        Write-Host "Didn't Work"
    }
}

ValidatePath $somePath 
# DIDN'T WORK

问题是它在方括号上失败了。

如何自动转义方括号以验证文件？

# Path needs to look like this
$somePath = "D:\some\path\name.of - my file ``[20_32_21``].mp4"
ValidatePath $somePath 
# WORKED!!!

Answer 1

使用-LiteralPath代替-Path; e.g：

if ( test-path -literalpath $path ) {
  ....
}

比尔

Answer 2

您可以尝试使用“test-path -literalpath $ path”吗？
