[Mono-devel-list] convert char[] in c struct to byte[] in C# struct??

[Michael J. Ryan]

Thanks, I just didn't "get" it... at this point, I
am reading the data directly from the file, I had wanted
to use the C api that was already written, but honestly
prefer all managed code... just kinda weird.. :)

Thanks a bunch though, will keep a note of this.
Beyond that, any idea why a char[]'s .ToString() would
keep giving me "System.Char[]" instead of the value?
Same went for Convert.ToString(char[]); (I'm using the
variable for the char[])
