Re: Unable to add image in .NET 3.5 using C#

Hope someone can help.

I am trying to add an image to a docx file using the SDK in a .net 3.5 application.

However, when I add the imagepart and try to populate the stream with the actual imagedata, no matter what I do, I get "Memorystream Not Expandable" exception thrown.

Initially tried multiple version of:
 var imagePart = mainpart.AddNewPart<ImagePart>("image/jpeg", sigId);
 using (var writer = new BinaryWriter(imagePart.GetStream()))
 {
     writer.Write(imageFileBytes);
     writer.Flush();
 }

The tried:
 var imagePart = mainpart.AddImagePart(ImagePartType.Jpeg,sigId);
 imagePart.FeedData(new MemoryStream(imageFileBytes,true));

Can anyone tell me why this is not working. The first snippet of code works in .NET 4.0.

Anyone done this in 3.5? Or are there any other way to get the actual imagepart into the doc?

Any help will be appreciated.

Sorry, in THIS case it also does not work in .NET 4.0.

And figured out it was a stream in a different routine about 3 levels up. Sigh.

Common issue with usage of the MemoryStream constructors.

For an expandable stream, you must instantiate the MemoryStream using the empty constructor.
