Powershell-命名参数和脚本内置函数？

Question

我正在尝试构建一个脚本，该脚本接受命名的参数-但是该脚本中也包含函数...这给我带来了一个问题，我看不到如何解决。 脚本c：\\ temp \\ example.ps1如下所示：

function test
{
 param($p1)
 write-host $p1
}

param(
 [parameter(mandatory=$false)]
 [switch]$EnableOption,
 [parameter(mandatory=$false)]
 [string]$Hostname
)

test -p1 $Hostname

这给了我：

param : The term 'param' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At C:\Temp\example.ps1:7 char:1
+ param(
+ ~~~~~
    + CategoryInfo          : ObjectNotFound: (param:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

如何解决此问题-以便将命名参数用于函数-还可以在“主”脚本中使用（在调用脚本时获取命令行参数）？

Answer 1

在脚本中更改顺序

param(
 [parameter(mandatory=$false)]
 [switch]$EnableOption,
 [parameter(mandatory=$false)]
 [string]$Hostname
)

function test
{
 param($p1)
 write-host $p1
}


test -p1 $Hostname

Param部分必须在代码的开头
