Is it possible to open memory mapped file in C# directly just like opening files directly in windows, say for example, I'm creating memory mapped file. through following code.
using System;
using System.IO.MemoryMappedFiles;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
MemoryMappedFile mmf = MemoryMappedFile.CreateNew("test.txt", 5);
MemoryMappedViewAccessor accessor = mmf.CreateViewAccessor();
var arun = new[] {(byte)'a', (byte)'r', (byte)'u', (byte)'n'};
for (int i = 0; i < arun.Length; i++)
accessor.Write(i, arun[i]);
Console.WriteLine("Memory-mapped file created!");
Console.ReadLine(); // pause till enter key is pressed
accessor.Dispose();
mmf.Dispose();
}
}
}
I need to open the file directly. Is it possible like opening file through
Process.start("test.txt");
from another process instead of reading values by the code .
MemoryMappedFile mmf1 = MemoryMappedFile.OpenExisting("test.txt");
MemoryMappedViewAccessor accessor1 = mmf1.CreateViewAccessor();
var value = accessor1.ReadByte(4);
If it possible to open memory mapped file directly? Please let me know.
Starting with the .NET Framework version 4, you can use managed code to access memory-mapped files in the same way that native Windows functions access memory-mapped files, as described in Managing Memory-Mapped Files in Win32 in the MSDN Library.
