Adding parameters to your functions is fairly easy. You can add a param() block and specify the parameters. But what if you wanted to assign values to different parameters based solely on type? Let's say you want a function that accepts both numbers and text, and depending on which type you submitted, choose a parameter. Here is how you can do that:
function Test-Binding {
[CmdletBinding(DefaultParameterSetName='Name')]
param(
[Parameter(ParameterSetName='ID', Position=0, Mandatory=$true)]
[Int]
$id,
[Parameter(ParameterSetName='Name', Position=0, Mandatory=$true)]
[String]
$name
)
[CmdletBinding(DefaultParameterSetName='Name')]
param(
[Parameter(ParameterSetName='ID', Position=0, Mandatory=$true)]
[Int]
$id,
[Parameter(ParameterSetName='Name', Position=0, Mandatory=$true)]
[String]
$name
)
$set = $PSCmdlet.ParameterSetName
"You selected parameterset $set"
if ($set -eq 'ID') {
"The numeric ID is $id"
} else {
"You entered $name as a name"
}
}
Try this:
Test-Binding 12
Test-Binding "Hello"
Test-Binding
Test-Binding "Hello"
Test-Binding
