示例1: WriteWavHeader

        /// <summary>
        /// A bare bones WAV file header writer
        /// </summary>        
        private static void WriteWavHeader(Stream stream)
        {
            // Data length to be fixed up later
            int dataLength = 0;

            // We need to use a memory stream because the BinaryWriter will close the underlying stream when it is closed
            MemoryStream memStream = null;
            BinaryWriter bw = null;

            // FXCop note: This try/finally block may look strange, but it is
            // the recommended way to correctly dispose a stream that is used
            // by a writer to avoid the stream from being double disposed.
            // For more information see FXCop rule: CA2202
