示例1: Seek
/// <summary>
/// Sets the position within the current stream.
/// </summary>
/// <returns>
/// The new position within the current stream.
/// </returns>
/// <param name="offset">A byte offset relative to the <paramref name="origin"/> parameter. </param>
/// <param name="origin">A value of type <see cref="T:System.IO.SeekOrigin"/> indicating the reference point used to obtain the new position. </param>
/// <exception cref="T:System.IO.IOException">An I/O error occurs. </exception>
/// <exception cref="T:System.NotSupportedException">The stream does not support seeking, such as if the stream is constructed from a pipe or console output. </exception>
/// <exception cref="T:System.ObjectDisposedException">Methods were called after the stream was closed. </exception>
