Passing parameter names through variables in PowerShell?

Question

PowerShell

PowerShell has Set constructs, such as

Set-Content -Path 'C:\Logs\1.txt' -Value 'Текст для вывода'

This command will output the values ​​to the file 'C:\Logs\1.txt'.
There are commands that can take the name of a parameter through an array with keys

-prelace @{Ключ=Значение}
-clear @{Ключ=Значение}

Everything is fine with them, they chew variables and instead of a value and instead of a key.

-prelace @{$Key=$Value}
-clear @{$Key=$Value}

For example if you do this

$Value= '-Value'
$Value.GetType().FullName - так мы узнаем что это System.String[]
Set-Content -Path 'C:\Logs\1.txt' $Value 'Текст для вывода'
Получим ошибку, нет параметра для приема значения 'Текст для вывода'

Actually the question is how it is possible to pass through a variable not only the value but also the key/parameter (-Path, -Value) to the command/function. Let me explain what the catch is, one value can correspond to two different keys, one for calling in a function, the second for passing through an array. In general, the crutch through the array works, but you always want something more.

Answer 1

$parms = @{'class'='Win32_BIOS';
'computername'='SERVER-R2';
'filter'='drivetype=3';
'credential'='Administrator'
}
Get-WmiObject @parms
something like this.
$parms.computername = "whatever" - if you need to change the parameter value on the fly.

Is splatting wrong?
