Value

true if the stream supports seeking; false if the stream is closed or if the System.IO.FileStream was constructed from an operating-system handle such as a pipe or output to the console.

Remarks

If a class derived from System.IO.Stream does not support seeking, calls to FileStream.Length, FileStream.SetLength(long), FileStream.Position, and FileStream.Seek(long, SeekOrigin) throw a NotSupportedException.

If the stream is closed, this property returns false.
