BindingCollection | Android Binding Collection with MVVM and DiffUtil | Model View Controller library

When I run the following cmdlets Get-IISSite | select Name, Bindings I get the IIS Site Names and the Bindings enumerated in a nice readable format like so:

Example 1

Default Web Site {http *:80:}
Site 1 {http *:804:, http *:80:site1.mysite.net}

When I pipe that into the Export-Csv cmdlet Get-IISSite | select Name, Bindings | Export-Csv c:\file.csv I get the following output:

Example 2

"Name","Bindings"
"Default Web Site","Microsoft.Web.Administration.BindingCollection"
"Site 1","Microsoft.Web.Administration.BindingCollection"`

I know the Export-Csv cmdlet calls .ToString() on each property of the object and that is why I am getting the Microsoft.Web.Administration.BindingCollection type name in what is the Bindings field. I have 2 questions:

1. How can I get an enumerated output to the CSV like example 1 displays?
2. How can I sort the items from the Bindings item as I wish?

When I call the getRange() method on a Binding object, I receive the following error:

I have a WPF application where I need to implement this concept:

There is a combobox and a datagrid. The combobox holds a list of sellers, and the datagrid holds the rates of items they sell.

I want something like this:
