I need to use BinaryReader.Read to read the file that more than 2GB (greater than the integer value range), the function parameters only support int32.

_BinaryReader.Read(_Buffer, 0, ChunkSize) 'ChunkSize value is 5GB (5,368,709,120), it's long value.

    Can you use a Memory Mapped File? MemoryMappedFile Class says:

    Memory-mapped files enable programmers to work with extremely large files

    So that appears to be what Microsoft intends to be used for such large files.
