Returning list of properties from a list of objects

I have a list of Tenants (call it TenantList), and it's composed of Tenant obj开发者_如何学Pythonects and they all have an ID property. How can I return an enumerable item composed of their ID properties?

You can use either

var result = TenantList.Select(t => t.ID)

or

var result = from tenant in TenantList select tenant.ID

TenantList.Select(t => t.ID)

TenantList.Select(t => t.ID);
