Assembly: mscorlib (in mscorlib.dll)
Parameters
- offset

Type:
System.Int64

- loc
-
Type:
System.IO.SeekOrigin
A value of type SeekOrigin, which acts as the seek reference point.
Return Value
Type: System.Int64The new position within the stream, calculated by combining the initial reference point and the offset.
| Exception | Condition |
|---|---|
| IOException | Seeking is attempted before the beginning of the stream. |
| ArgumentOutOfRangeException | offset is greater than MaxValue. |
| ArgumentException | |

This method overrides Stream.Seek.
Seeking to any location beyond the length of the stream is supported.
Do not use the Seek method to determine the new position in the stream if the MemoryStream was initialized with a non-zero offset. If you do, Seek will return an inaccurate value. Instead, use the Position property to get the new position of the stream.
