Question

I have a binary file to which I want to append a chunk of data at the end of the file, how can I achieve this using C# and .net? Also is there anything to consider when writing to the end of a binary file? Thanks a lot for your help.

Answer 1

private static void AppendData(string filename, int intData, string stringData, byte[] lotsOfData)
{
    using (var fileStream = new FileStream(filename, FileMode.Append, FileAccess.Write, FileShare.None))
    using (var bw = new BinaryWriter(fileStream))
    {
        bw.Write(intData);
        bw.Write(stringData);
        bw.Write(lotsOfData);
    }
}
