foreach (IShape shapeToMove in slide.Shapes)
{
    if (shapeToMove.Name.Contains("Slide Number Placeholder"))
    {
        shapeToMove.Left =0;                                                  
     }

    else if (shapeToMove.Name.Contains("Date Placeholder"))
    {
        shapeToMove.Left = presentation.SlideSize.Size.Width / 2;
       
        (shapeToMove as IAutoShape).TextFrame.TextRange.Paragraph.Text = DateTime.Now.ToString("dd.MM.yyyy");
        (shapeToMove as IAutoShape).TextFrame.IsCentered = true;
    }
