Save stream to the file

Question

Hello. How can I write Byte [] buf to the file without turning it into string ?

public Int32 OnWriteData(Byte[] buf, Int32 size, Int32 nmemb, Object extraData)
{
    SockBuff = SockBuff + System.Text.Encoding.UTF8.GetString(buf);
    return size * nmemb;
}

Been trying to find something working for hours now.

Answer 1

System.IO.File.WriteAllBytes

Answer 2

Use the above answer if you just want a single file with nothing but your byte buffer, if you want to do multiple byte buffer writes to one file though, I write bytes like so:

using (StreamWriter myStreamWriter = new StreamWriter(filePath))
{
    // Some logic or something, who knows
    myStreamWriter.BaseStream.Write(byteBuffer1, 0, byteBuffer1.Length);
    // Some logic or something, who knows
    myStreamWriter.BaseStream.Write(byteBuffer2, 0, byteBuffer2.Length);
}
