This case fails at the Get with the exception below.
[[
    <Test()> _
    Public Sub CallByName_All_OnMemoryStream()
        Dim strm As New System.IO.MemoryStream
        ' SET
        CallByName(strm, "Position", CallType.Set, 3)
        Assert.AreEqual(3, strm.Position, "#2")
        ' METHOD
        Dim data() As Byte = {1, 2, 3, 4, 5}
        Dim params() As Object = {data, 0, data.Length}
        CallByName(strm, "Write", CallType.Method, params)
        Assert.AreEqual(8, strm.Position, "#3")
        ' GET
        Assert.AreEqual(8, CallByName(strm, "Position", CallType.Get, Nothing),
"#1")
    End Sub
