I’d like to allow users of a web-based CMS to upload Flash files and include them in the content. I’ll probably use SWFObject to render the flash , but I need the width and height. Is this possible to determine these via C# when I do the upload?

Thanks.

  1. There is likely an easier way but,

    you can download ‘FlashTools.zip’ from http://blogs.msdn.com/mswanson/archive/2006/10/15/example-c-code-for-reading-flash-swf-files.aspx and compile the project. Then add a reference to the ‘FlashTools.dll’ assembly. You can then get height/width using:

    SWFFile swf = new SWFFile(fileLocation); Response.Write('Height:' + swf.FrameHeight/20 + ' Width:' + swf.FrameWidth/20);

    I’ve tested this and it shows the correct information.
