Sorry about the last... Anyway, here's the question:
I've been working on some C# routines to process strings in and out of various encodings. The hope is that I can just let the user type in the encoding they want and I'll do a pretty good job of converting. Basically, I take a string as input, write it to a byte array MemoryStream and then get the bytes of the conversion out.
The oddity in my question is that when I use System.Text.UTF8Encoding as an argument to my StreamWriter, I don't get the byteorder mark in the output, but when I use System.Text.Encoding.GetEncoding ("utf-8"); I do. Shouldn't these be the same, or am I missing something basic? Seems odd. Can someone explain why?
Thanks

Example code:
public byte [] Convert (string in, Encoding enc, out length)
{
MemoryStream out_stream = new MemoryStream(in.Length*3); // allow for encoding switch expansion
System.IO.StreamWriter writer = new System.IO.StreamWriter (out_stream, enc);
writer.Write (input);
writer.Flush(); // Flush but don't close, so we can get the MemoryStream used count
byte [] output = out_stream.GetBuffer();
length = out_stream.Length;
return output;
}
byte [] test = Convert ("test", System.Text.UTF8Encoding); // no bytemark
test = Convert ("test", System.Text.GetEncoding ("utf-8")); // bytemark
