Use dynamic (ExpandoObject) properties as column headers in output

I have a script that produces an array of dynamic objects whose properties are all identical. It would be nice to have the output formatted as a single table whose columns are the properties of the dynamic objects rather than a table with a single column, Items, with links in each row to the Key/Value pairs.

    LinqPad already provides that, but the compile time support from .NET is missing:

    Dim ue = From s In Strings.Split("Name1:Value1; Name2:2" & vbCrLf & "Name1:Value2; Name2:3", vbCrLf) _
    Let e=(Strings.Split(s,"; ").ToDictionary(Function(f)f.Split({":"c},2)(0),Function(f)f.Split({":"c},2)(1))) _
    Select x=(Function(d As Dictionary(Of String,String))
    Dim r = New Dynamic.ExpandoObject
    Dim i As IDictionary(Of String,Object)=r
    For Each kv In d
    i.Add(kv.Key,kv.Value)
    Next
    Return r
    End Function)(e)

    ue.Dump

    Call (From x In ue _
    Select Name1=CStr(x(0).Value), Name2=CInt(x(1).Value)).Dump

    'ExpandoObject not designed with VB in mind because these fail x!Name1 x!Name2 :-(
