System.IO.FileNotFoundException When Using FileStream with FileShare in .NET 6
After trying multiple solutions online, I still can't figure this out. This might be a silly question, but I'm working with a `System.IO.FileNotFoundException` when trying to open a file with `FileStream` using `FileShare.ReadWrite` in my .NET 6 application. The goal is to allow multiple processes to read from and write to the same file, but whenever I attempt to access the file, I get the following behavior message: ``` System.IO.FileNotFoundException: Could not find file 'C:\path\to\file.txt'. ``` I've confirmed that the file exists at that location, and I can open it manually without issues. Here’s a snippet of my code: ```csharp using System; using System.IO; class Program { static void Main() { string filePath = "C:\path\to\file.txt"; try { using (FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) { // Read from the file } } catch (FileNotFoundException ex) { Console.WriteLine(ex.Message); } } } ``` I've verified the permissions for the file and ensured that no other process is holding an exclusive lock on it. I also checked the `FileMode`, and it seems correct because I just want to open an existing file. I've tried wrapping the file access code in a retry loop, hoping it might be a timing scenario, but that didn't resolve the question. Is there something I’m missing regarding the file path or the way `FileStream` is being used? Any insights would be greatly appreciated! For context: I'm using C# on Windows. I'd really appreciate any guidance on this. I'm working on a CLI tool that needs to handle this. I'd really appreciate any guidance on this.
