How do I pulse digital lines using C# - Using PCI 6025E

Hi,

I need to generate finite pulse trains on my digital lines for a PCI 6025E board. I am using the late NIDAQmx driver. Currently I create a task and writer for the corresponding ports and then I write digital high then write digital low to artificially create a pulse. However this is not fast enought. I am unsure of how to do this as I can't seem to find good documentation for C#.

Any help would be appreciated!

Thanks
