Convert Tiff memory stream to Bitmap

Question

I'm working on a Outlook add-in that's converts attachments. When trying to convert an Tiff attachment to a Bitmap I get:

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException. Oveloaded method System.Windows.Media.Imaging.TiffBitmapDecoder.TiffBitmapDecoder has invallid arguments.

The code:

const string PR_ATTACH_DATA_BIN = "http://schemas.microsoft.com/mapi/proptag/0x37010102";

// Retrieve the attachment as a byte array
var attachmentData = myOutlookAttachement.PropertyAccessor.GetProperty(PR_ATTACH_DATA_BIN);

TiffBitmapDecoder decoder = new TiffBitmapDecoder(attachmentData, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
BitmapSource bitmapSource = decoder.Frames[0];
Bitmap bmp = new Bitmap(bitmapSource.PixelWidth, bitmapSource.PixelHeight, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);

Thanks to Alex KI found the answer:

const string PR_ATTACH_DATA_BIN = "http://schemas.microsoft.com/mapi/proptag/0x37010102";

    // Retrieve the attachment as a byte array
    var attachmentData = myOutlookAttachement.PropertyAccessor.GetProperty(PR_ATTACH_DATA_BIN);
    Stream stream = new MemoryStream(attachmentData);

    TiffBitmapDecoder decoder = new TiffBitmapDecoder(stream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
    BitmapSource bitmapSource = decoder.Frames[0];
    Bitmap bmp = new Bitmap(bitmapSource.PixelWidth, bitmapSource.PixelHeight, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);
