Copy C# 
public static void PrintLinkOverridesInView(View view)
{
    var ids = new FilteredElementCollector(view.Document)
                  .WhereElementIsElementType()
                  .OfType<RevitLinkType>()
                  .Select(link => link.Id)
                  .ToList();

    ids.AddRange(new FilteredElementCollector(view.Document)
                     .WhereElementIsNotElementType()

        {
            message.AppendLine(string.Format("Element with Id - {0} doesn't have graphical overrides in the view.",
