Seek Method

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

Sets the position within the current stream to the specified value.

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

Syntax

'Declaration
Public Overrides Function Seek ( _
    offset As Long, _
    origin As SeekOrigin _
) As Long

public override long Seek(
    long offset,
    SeekOrigin origin
)

public:
virtual long long Seek(
    long long offset, 
    SeekOrigin origin
) override

abstract Seek : 
        offset:int64 * 
        origin:SeekOrigin -> int64 
override Seek : 
        offset:int64 * 
        origin:SeekOrigin -> int64 

public override function Seek(
    offset : long, 
    origin : SeekOrigin
) : long

Parameters

• offset
  Type: System. . :: . .Int64
  The new position within the stream. This is relative to the loc parameter, and can be positive or negative.

• origin
  Type: System.IO. . :: . .SeekOrigin
  A value of type SeekOrigin, which acts as the seek reference point.

Return Value

Type: System. . :: . .Int64
The new position within the stream, calculated by combining the initial reference point and the offset.

Remarks

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.

.NET Framework Security

• Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see dd66cd4c-b087-415f-9c3e-94e3a1835f74.
