System.IO.MemoryMappedFiles.MemoryMappedFile.CreateViewAccessor Method

Creates a System.IO.MemoryMappedFiles.MemoryMappedViewAccessor that maps to a view of the memory-mapped file, and that has the specified offset and size.

Syntax

public MemoryMappedViewAccessor CreateViewAccessor (long offset, long size)

Parameters

offset
The byte at which to start the view.
size
The size of the view. Specify 0 (zero) to create a view that starts at offset and ends approximately at the end of the memory-mapped file.

Returns

A randomly accessible block of memory.

Remarks

You can use the view returned by this method for random access to a memory-mapped file.

To create a complete view of the memory-mapped file, specify 0 (zero) for the size parameter. If you do this, the size of the view might be smaller or larger than the size of the source file on disk. This is because views are provided in units of system pages, and the size of the view is rounded up to the next system page size.
