    Resume fileDataHolder = (Resume)View.CurrentObject;
    if(fileDataHolder.File == null) {
        fileDataHolder.File = View.ObjectSpace.CreateObject<FileData>();
    }
   fileDataHolder.File.LoadFromStream("screenshot.png", fs);
}

VB.NET

Using fs As FileStream = File.OpenRead("D:\screenshot.png")
    Dim fileDataHolder As [Resume] = CType(View.CurrentObject, [Resume])
    If fileDataHolder.File Is Nothing Then
        fileDataHolder.File = View.ObjectSpace.CreateObject(Of FileData)()
    End If
   fileDataHolder.File.LoadFromStream("screenshot.png", fs)
End Using
