Seek Method

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

When overridden in a derived class, sets the position within the current stream.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public abstract long Seek(
	long offset,
	SeekOrigin origin
)

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.

Return Value

Type: System..::..Int64
The new position within the current stream.

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.
