My target is an SD card and I do not have any database capabilities like SQL.. In the old VB6 days you could create random files, and by defining the record length you could easily move from one record to the next. But I am at loss to find a similar type of functionality in C#. I can understand that to do this I will need to create a class, and serialise that class before storing the object on the disk.. But moving to a particular record has gotten me stuck. The only way I can see at the moment is to use the RecordLength * RecordNum and then SEEK to that byte location on the disk file. What level are you working at with the SD card? low-level SPI, secure or FAT file system? It's a 512 byte block, so you probably want your record to use a multiple of that, or pad it up. (memory's cheap) My memory space is also small so I cannot load the file into memory and move through it as a collection. Any suggestions/advice.
