Convert PowerShell Command to Script

Question

The PowerShell command below turns off the screen when run from a batch file (or command prompt). I would prefer to run this as a PowerShell script.

Turn Off Screen - TechNet Script Center

powershell (Add-Type '[DllImport(\"user32.dll\")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)

I looked at Add-Type - Microsoft Docs, but I could not get the parameters correct.

What is the equivalent PowerShell script for this?

Add-Type -MemberDefinition @"
    [DllImport("user32.dll")]
    public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);
"@  -Name "Win32SendMessage" -Namespace "Win32Functions"

[Win32Functions.Win32SendMessage]::SendMessage(-1,0x0112,0xF170,2)
