using Stream writer to Write a specific bytes to textfile

Question

Well I'm trying to write some values and strings to a text file.
but this text file must contain 2 bytes

These are the 2 bytes I want to insert to my text file after finishing writing the other values to it:

I tried this method but I have no idea how to write bytes through it

using (StreamWriter sw = new StreamWriter(outputFilePath, false, Encoding.UTF8))

I have no idea about how to write them to the text file after putting the strings I want on it.

If I recall correctly from your question. You want to write strings to a file and then write bytes to it?

This example will do that for you:

using (FileStream fsStream = new FileStream("Bytes.data", FileMode.Create))
using (BinaryWriter writer = new BinaryWriter(fsStream, Encoding.UTF8))
{
    // Writing the strings.
    writer.Write("The");
    writer.Write(" strings");
    writer.Write(" I");
    writer.Write(" want");
    writer.Write(".");

    // Writing your bytes afterwards.
    writer.Write(new byte[]
                 {
                     0xff,
                     0xfe
                 });
}

When opening the "Bytes.data" file with a hex editor you should see these bytes:
