How to implement guide with asynchronous file i/o in c# - getting filenotfound handling despite file existing
I'm stuck on something that should probably be simple... I'm working with a frustrating question while trying to read a file asynchronously using .NET 6. I have a method that opens a file, reads its contents, and returns them as a string. However, I'm getting a `FileNotFoundException`, even though I can see the file exists in the specified path. Here's the code snippet: ```csharp using System; using System.IO; using System.Threading.Tasks; public class FileReader { public async Task<string> ReadFileAsync(string filePath) { try { using (StreamReader reader = new StreamReader(filePath)) { return await reader.ReadToEndAsync(); } } catch (FileNotFoundException ex) { throw new Exception("File not found: " + ex.Message); } } } ``` I call this method from another asynchronous method like this: ```csharp public async Task ProcessFile() { var fileReader = new FileReader(); string content = await fileReader.ReadFileAsync("C:\Files\myFile.txt"); Console.WriteLine(content); } ``` When I run the `ProcessFile` method, I consistently get this behavior: ``` System.IO.FileNotFoundException: Could not find file 'C:\Files\myFile.txt'. ``` I've double-checked the file path, and I have also tried using `Path.Combine` to ensure it's formatted correctly. Additionally, I verified that the application has permission to access the file location. What could be causing this scenario? Is there something I'm missing regarding asynchronous file operations or file paths in a different environment? Any insights would be greatly appreciated! This is part of a larger application I'm building. What am I doing wrong?
