Ja erläutere mal, was so schief geht!?!
Edit außerdem:
Zitat:
If Count is 0, CopyFrom sets Source position to 0 before reading and then copies the entire contents of Source into the stream. If Count is greater than or less than 0, CopyFrom reads from the current position in Source.
Position setzen, Größe auslesen und an CopyFrom weiterreichen --> nicht notwendig
