Stream.Seek Method
When overridden in a derived class, sets the position within the current stream.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- offset
- Type: System.Int64
A byte offset relative to the origin parameter.
- origin
- Type: System.IO.SeekOrigin
A value of type SeekOrigin indicating the reference point used to obtain the new position.
| Exception | Condition |
|---|---|
| IOException | An I/O error occurs. |
| NotSupportedException | The stream does not support seeking, such as if the stream is constructed from a pipe or console output. |
| ObjectDisposedException | Methods were called after the stream was closed. |
Use the CanSeek property to determine whether the current instance supports seeking.
If offset is negative, the new position is required to precede the position specified by origin by the number of bytes specified by offset. If offset is zero (0), the new position is required to be the position specified by origin. If offset is positive, the new position is required to follow the position specified by origin by the number of bytes specified by offset.
Classes derived from Stream that support seeking must override this method to provide the functionality described above.
Seeking to any location beyond the length of the stream is supported.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
