MemoryStream::Seek Method

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

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

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

Parameters

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

ExceptionCondition
IOException

Seeking is attempted before the beginning of the stream.

ArgumentOutOfRangeException

offset is greater than MaxValue.

ArgumentException

There is an invalid SeekOrigin.

-or-

offset caused an arithmetic overflow.

ObjectDisposedException

The current stream instance is closed.

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.

This code example is part of a larger example provided for the MemoryStream class.


// Set the stream position to the beginning of the stream.
memStream->Seek( 0, SeekOrigin::Begin );
