Question

I have a byte array which I got back from a FileStream.Read and I would like to turn that into a string. I’m not 100% sure of the encoding – it’s just a file i saved to disk – how do I do the conversion? Is there a .NET class that reads the byte order mark and can figure out the encoding for me?

If File.ReadAllText will read the file correctly, then you have a couple of options.

Instead of calling BeginRead, you could just call File.ReadAllText asynchronously:

    delegate string AsyncMethodCaller(string fname);      static void Main(string[] args)     {         string InputFilename = 'testo.txt';         AsyncMethodCaller caller = File.ReadAllText;         IAsyncResult rslt = caller.BeginInvoke(InputFilename, null, null);          // do other work ...          string fileContents = caller.EndInvoke(rslt);     } 

Or you can create a MemoryStream from the byte array, and then use a StreamReader on that.
