I created a method for one of my projects, here is the method try using it and see if it works:

   public void ResizeImage(string sImageFile, decimal dWidth, decimal dHeight, string sOutputFile)
    {
        Image oImg = Bitmap.FromFile(sImageFile);
        Bitmap oBMP = new Bitmap(decimal.ToInt16(dWidth), decimal.ToInt16(dHeight));

        Graphics g = Graphics.FromImage(oBMP);
        g.PageUnit = pgUnits;
        g.SmoothingMode = psMode;
        g.InterpolationMode = piMode;
        g.PixelOffsetMode = ppOffsetMode;

        g.DrawImage(oImg, 0, 0, decimal.ToInt16(dWidth), decimal.ToInt16(dHeight));

        ImageCodecInfo oEncoder = GetEncoder();
        EncoderParameters oENC = new EncoderParameters(1);

        oENC.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, plEncoderQuality);

        oImg.Dispose();

        oBMP.Save(sOutputFile, oEncoder, oENC);
        g.Dispose();

    }
