[C#]Interprocess Communications (File Mapping)

Send:

using System.IO.MemoryMappedFiles;

namespace ConsoleApplication_IPC_FileMappingSend
{
    class Program
    {
        static void Main(string[] args)
        {

            MemoryMappedFile mmf = MemoryMappedFile.CreateNew("test", 1000);

            MemoryMappedViewAccessor accessor = mmf.CreateViewAccessor();

            accessor.Write(500, 42);

            Console.WriteLine("Memory-mapped file created!");

            Console.ReadLine();

            accessor.Dispose();

            mmf.Dispose();


        }
    }
}


Recvive:

using System.IO.MemoryMappedFiles;


namespace ConsoleApplication_IPC_FileMappingRec
{
    class Program
    {
        static void Main(string[] args)
        {
            MemoryMappedFile mmf = MemoryMappedFile.OpenExisting("test");

            MemoryMappedViewAccessor accessor = mmf.CreateViewAccessor();
            int value = accessor.ReadInt32(500);
            Console.WriteLine("the answer is {0}", value);

            Boolean zeon1 = accessor.CanRead;
             
            mmf.Dispose();
           
            Console.ReadLine();
        }
    }
}
