PowerShell how to create an object (Note to Self)

$test = new-object psobject -Property @{
Name = 'John Doe'
Age = 3
Amount = 10.1
MixedItems = (1,2,3,"a")
NumericItems = (1,2,3)
StringItems = ("a","b","c")
}

Another example:

$Object = New-Object PSObject -Property @{
        LineNumber       = $LineNumber
        Date             = $TodayDate
        ServerName       = $svr
        DatabaseName     = $Database
        UserName         = $user.name
        CreateDate       = $CreateDate
        DateLastModified = $DateLastModified
        AsymMetricKey    = $user.AsymMetricKey
        DefaultSchema    = $user.DefaultSchema
        HasDBAccess      = $user.HasDBAccess
        ID               = $user.ID
        LoginType        = $user.LoginType
        Login            = $user.Login
        Orphan           = ($user.Login -eq "")
    }
