Creating Profiles / available methods list on iControl?

I'll post the rest of the functions I end up creating in case they will be of use to anyone. This one was a little more interesting as I had to learn what a struct was. It may be worth beefing up the documentation around New-Object -TypeName iControl.LocalLBProfileString; to a non-programmer this stuff isn't very obvious, translating the one example I found from Java to Powershell wasn't simple for me.

I'm also still not clear why I need to insert the LocalLBProfileString into an Array before I can use it?

function Create-ClientSSLProfile()

 Check whether a ClientSSL Profile exists, create it if required
-------------------------------------------------------------------------
{
  Param([string] $profileName);
  $ClientSSLArray = @()
  $ClientSSLArray = (Get-F5.iControl).LocalLBProfileClientSSL.get_list()
  If ($ClientSSLArray -contains $profileName) {
    Write-Host "ClientSSL Profile: $profileName already exists" -ForegroundColor Cyan
  } Else {
    try {
   Create LocalLBProfileString Structs for certificate and keys
  $defaultCert = New-Object -TypeName iControl.LocalLBProfileString;
  $defaultCert.value = "default";
          $defaultCert.default_flag = "true";
          $defaultCerts = (, $defaultCert);
          $defaultKey = New-Object -TypeName iControl.LocalLBProfileString;
          $defaultKey.value = "default";
          $defaultKey.default_flag = "true";
          $defaultKeys = (, $defaultKey);
   Create ClientSSL profile
  (Get-F5.iControl).LocalLBProfileClientSSL.create( $profileName, $defaultCerts, $defaultKeys )
  Write-Host "Created ClientSSL Profile: $profileName" -ForegroundColor Green
} catch {
  Write-Host "There was an exception thrown creating ClientSSL Profile: $profileName" -ForegroundColor Red
  $Error[0]
}
  }
}
