Why am I getting this?

[Scott M.]

Why does the following code produce a string ("Byte me!") in the output
file, rather than byte data as integers (66 121 116 101 32 109 101 33)?

Dim fs As System.IO.FileS tream = System.IO.File. Open("C:\myMess age.dat",
IO.FileMode.Cre ate)
Dim msg As String = "Byte me!"
Dim msgByteArray() As Byte = System.Text.Enc oding.Default.G etBytes(msg)
fs.Write(msgByt eArray, 0, msgByteArray.Le ngth)

....And, how do I get the output file to have the byte array data?

PS - I know I could use a different Stream type, but I want to do this using
a FileStream.

It does show those values. I'm guessing you are using a text editor rather
than something like Notepad++ that can show the values as bytes. The bytes
you want and the string you got are the same.

As Mike says, you are actually getting the result you want.

However, you could try a BinaryWriter if you want to write other data types
(e.g. Integer) in binary format.

Scott,

I am not sure, however for one thing I am sure, your default text encoding
is not ASCII while you are showing us here a decimal representation of bit
values in 7 bit (bit)words confirm ASCII.

Hello Scott,

Apart from Mike, Davud and Cor's suggestions, if you expect to see the
integers (66 121 ...) in the output file, we can do it in this way:

Dim fs As System.IO.FileS tream =
System.IO.File. Open("C:\myMess age.dat", IO.FileMode.Cre ate)
Dim msg As String = "Byte me!"
Dim msgByteArray() As Byte =
System.Text.Enc oding.Default.G etBytes(msg)
For Each bt As Byte In msgByteArray
Dim tmpByteArray() As Byte =
System.Text.Enc oding.Default.G etBytes(bt.ToSt ring())
fs.Write(tmpByt eArray, 0, tmpByteArray.Le ngth)
Next
fs.Close()

Hope it helps,

If you have any other concerns or questions, please feel free to let me
know.
