Convert bitmaps to one multipage TIFF image in .NET 2.0

Question

How can i convert an array of bitmaps into a brand new image of TIFF format, adding all the bitmaps as frames in this new tiff image?

using .NET 2.0.

Came across this post after a bit of searching on Google. I tried the code that was in the post by a'b'c'd'e'f'g'h', but that didn't work for me. Perhaps, I was not doing something correctly.

In any case, I found another post that saved images to multi page tiffs. Here is the link to the post: http://www.bobpowell.net/addframes.htm

Also, here is the code that worked for me. It should be identical to that post.

Encoder encoder = Encoder.SaveFlag;
ImageCodecInfo encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == "image/tiff");
EncoderParameters encoderParameters = new EncoderParameters(1);
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.MultiFrame);

// Save the first frame of the multi page tiff
Bitmap firstImage = (Bitmap) _scannedPages[0].RawContent;
firstImage.Save(fileName, encoderInfo, encoderParameters);

encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.FrameDimensionPage);

// Add the remaining images to the tiff
for (int i = 1; i < _scannedPages.Count; i++)
{
   Bitmap img = (Bitmap) _scannedPages[i].RawContent;
   firstImage.SaveAdd(img, encoderParameters);
}

// Close out the file
encoderParameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.Flush);
firstImage.SaveAdd(encoderParameters);
