How can you test if an object has a specific property?

You can use Get-Member

if(Get-Member -inputobject $var -name "Property" -Membertype Properties){
#Property exists
}

Like this?

 [bool]($myObject.PSobject.Properties.name -match "myPropertyNameToTest")

This is succinct and readable:

"MyProperty" -in $MyObject.PSobject.Properties.Name

We can put it in a function:

function HasProperty($object, $propertyName)
{
    $propertyName -in $object.PSobject.Properties.Name
}
