A long containing the current position of this stream.
Type Reason NotSupportedException The current stream does not support seeking. System.IO.IOException An I/O error occurred. System.IO.EndOfStreamException Attempted seeking past the end of a stream that does not support this. ArgumentOutOfRangeException The value specified for a set operation is negative.
Seeking to any location beyond the length of the stream is supported. When you seek beyond the length of the file, the file size grows. In Microsoft Windows NT and newer, any data added to the end of the file is set to zero. In Microsoft Windows 98 or earlier, any data added to the end of the file is not set to zero, which means that previously deleted data is visible to the stream. Setting the position of the stream to a large value beyond the end of the stream in Windows 98 or earlier may result in an exception being raised.
