Read JQuery memory files

I have an application that writes to memory a result in the following way:

 using (MemoryMappedFile mmf = MemoryMappedFile.CreateOrOpen(sMemfile, 1028))
 {
    using (MemoryMappedViewStream stream = mmf.CreateViewStream())
    {
         BinaryWriter writer = new BinaryWriter(stream);
         writer.Write(resultado);
     }
 }

I know that to read the result from another application the following process is used:

using (MemoryMappedFile mmfile = MemoryMappedFile.OpenExisting(sMemfile))
{
     using (MemoryMappedViewStream stream = mmfile.CreateViewStream())
     {
           BinaryReader reader = new BinaryReader(stream);
           resultado = reader.ReadString();
     }
}

But I would like to do the latter from a website with JQuery, is there any way or method similar to MemoryMappedFile that allows me to read what my application sent me? Thanks!
