TagTo return the tag in the first index.
Or the much nicer:
Tag["chdr"]Which would return the tag named "chdr".
A tag object contains 3 feilds.
Name, a 4 character ASCII string which contains the tag name
Size, an Int32 which stores the size of the entire tag(Including the name and size bytes)
Data, a byte array containing the tag's information.
The Data field can be accessed via byte array or BinaryReader.
Tag files can be initialized either directly from a STFS file(using DJ SkunkieButt's X360 Library), or from an already extracted file, and even directly from a stream.
Here is an example of me loading a Tag from a STFS(con) file.
Derp = new Tag(); Derp.LoadFromSTFS(openFileDialog1.FileName);
Included in the download is the Library its self, along with the source of an application that shows how to use it properly.
I only ask that you give credit to me and DJ SkunkieButt for its use, and maybe add some of your tag research to the modhalo wiki.
