If you try to load the same Dicom file using any of LEADTOOLS demos that ship with the SDK, do you face the same issue?

Do you face this problem with any Dicom file or with specific files?

What is the build number (version info) of LEADTOOLS .Net DLLs that you use?

Please send me a sample dicom file that shows the problem?

When you want to attach any files, please put them all in ZIP or RAR file. Also, don't use preview when you have attachment.
If you have any problem in attaching files to the forum, you can send the files in a ZIP of RAR file to support@leadtools.com. Don't forget to mention this forum post in your email to support.

Thanks,

i face the same exception when trying use the C# Demo but i cant make any thing !!!!!! with all Dicom files

Did you try to load your Dicom images using any of our demos shipped with the toolkit? Do you get the same issue? If yes, does it appear when you try to use our Dicom images in the following folder:
[LEADTOOLS15]\Images
If it appears only with your Dicom files, can you send me a sample file in a ZIP or RAR file? If you do not want to post the file here, you can send it to support@leadtools.com and mention this post. If it appears with our images, please give me details how to reproduce it using our demos. Also, please tell me what build number (version info) of LEADTOOLS .Net DLLs that you use?
