Exceptions

NotSupportedException

The stream does not support seeking.

IOException

An I/O error occurred.

ArgumentOutOfRangeException

Attempted to set the position to a negative value.

EndOfStreamException

Attempted seeking past the end of a stream that does not support this.

Examples

The following example uses the Length and Position properties to check for an end-of-file condition.

if ( s->Length == s->Position )
{
   Console::WriteLine( "End of file has been reached." );
}

if( s.Length==s.Position )
{
   Console.WriteLine("End of file has been reached.");
}

if s.Length = s.Position then
    printfn "End of file has been reached."

If s.Length = s.Position Then
    Console.WriteLine("End of file has been reached.")
End If

Remarks

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. Any data added to the end of the file is set to zero.
