I used C# to create some bitmaps and save them as a TIFF file. Now i want to
add metadata to the TIFF file. How can i do this?

You have many choices. They include the following:
1) Use the COM interface IPropertySetStorage.
2) Net 2.0 System.Drawing.Imaging PropertyItem Class
3) Net 3.0 System.Media.Imaging

Of the three, Net 3.0 is the easiest to work with.

See the following for an example:

See the GDI+ FAQ for a neat image metadata reader that also demonstrates how
to write.
