Trouble Implementing Memory-Mapped Files in C# for Large Data Processing - Access Violation handling
After trying multiple solutions online, I still can't figure this out... I'm learning this framework and Quick question that's been bugging me - I'm relatively new to this, so bear with me... I'm working on a data processing application in C# using .NET 6, where I need to handle large datasets efficiently. I decided to use memory-mapped files to enable multiple processes to read and write data concurrently. However, I'm working with an `AccessViolationException` when trying to write to the memory-mapped file. Here's the relevant code snippet: ```csharp using System; using System.IO; using System.IO.MemoryMappedFiles; class Program { static void Main(string[] args) { string mapName = "Local\MyMemoryMap"; using (var mmf = MemoryMappedFile.CreateNew(mapName, 1024 * 1024)) { using (var accessor = mmf.CreateViewAccessor()) { // Trying to write data accessor.Write(0, 42); } } } } ``` When I run this, I get the following exception: ``` Unhandled exception. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ``` I've tried running the program with elevated permissions, thinking it might be a security scenario, but the behavior continues. I'm also using the `Local\` prefix for the memory-mapped file name, which I understand is necessary for access across different processes. Additionally, I've checked that my application targets x64 and I'm not trying to access the mapped file from a 32-bit process. I even added some delay before writing to allow time for the file to be created, but that didn’t resolve the scenario either. What could be causing this access violation, and how can I properly implement memory-mapped files in this scenario? This is part of a larger web app I'm building. This is part of a larger API I'm building. Any ideas what could be causing this? The project is a mobile app built with C#. This is my first time working with C# stable. I'd be grateful for any help.
