Hi Bernd,
the datasheet of the MIFARE UltraLight C
http://www.nxp.com/documents/data_sheet/MF0ICU2.pdf
explains on pages 29 and 30 the authentication procedure.
The byte sequence used, depends on the library you use for communication. On PCs the PC/SC library is widely used and this library also is available for C#. Please refer to the manual of your reader how the PC/SC library is implemented for this reader. In this manual you will find examples how to pack the UltraLight C commands into write methods.
Regards,
The MIFARE Team
