How do I map PowerShell objects to windows form combo boxes?

$contracts = Get-MsolPartnerContract -All | select Name, DefaultDomainName, TenantID, ContractType | sort Name

$myform.combobox_contracts.DisplayMember = "{Name}"
$myform.combobox_contracts.ValueMember = "{TenantID}"
$myform.combobox_contracts.DataSource = $contracts

Trying to get something like the above to work in order to make mapping and selection of data easier.

For reference the Get-MSOLPartnerContract command above returns data like the following:

Name=Company Name;
DefaultDomainName=example.tld;
TenantID=<GUID>;
ContractType=[ResellerPartnerContract|SupportPartnerContract];

Currently this just displays the entire powershell object e.g.

@{Name=Microsoft;DefaultDomainName=Microsoft.com;TenantID=<GUID>;ContractType=ResellerPartnerContract}

I have tried changing combobox.displayname to:

• Name
• {Name}
• $Contract | Get-Member -Name Name
• $_.Name
• ($Contract | Get-Member).Name

Will need to do something similar for combobox.valuemember.

I assume I am not too far off what is needed but just cannot quite get the correct combination. Thanks for any suggestions!

EDIT SOLVED: Told you all I was close! See the last line with conversion [collections.arraylist]$contracts

$contracts = Get-MsolPartnerContract -All | Select-Object Name, DefaultDomainName, TenantID, ContractType | Sort-Object Name

$myform.combobox_contracts.DisplayMember = "Name"
$myform.combobox_contracts.ValueMember = "TenantID"
$myform.combobox_contracts.DataSource = [collections.arraylist]$contracts
