using System.IO.MemoryMappedFiles; // Open an existing memory-mapped file named "test_file" MemoryMappedFile mmf = MemoryMappedFile.OpenExisting("test_file");
using System.IO.MemoryMappedFiles; // Open an existing memory-mapped file named "test_file" with read access MemoryMappedFile mmf = MemoryMappedFile.OpenExisting("test_file", MemoryMappedFileRights.Read);In this example, we are using the MemoryMappedFile.OpenExisting method to open an existing file named "test_file" with read access. Package library: System.IO.MemoryMappedFiles is the package library used in these examples. This package provides classes for creating, reading, and writing to memory-mapped files.
