MemoryMappedFile.CreateViewStream Method (Int64, Int64)
Creates a stream that maps to a view of the memory-mapped file, and that has the specified offset and size.
Assembly: System.Core (in System.Core.dll)
The byte at which to start the view.
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.
Return ValueType: System.IO.MemoryMappedFiles.MemoryMappedViewStream
A stream of memory that has the specified offset and size.
You can use the stream returned by this method for sequential access to a memory-mapped file, such as for inter-process communications.
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.
