Trouble with Asynchronous File Access in C# - StreamReader Not Reading Data as Expected
I'm sure I'm missing something obvious here, but I'm working with an scenario with asynchronous file access in C#. I have a method that reads data from a text file using `StreamReader`, but the results are sometimes incomplete or missing when using `await`. Here's a simplified version of my code: ```csharp public async Task<string> ReadFileAsync(string filePath) { using (var reader = new StreamReader(filePath)) { return await reader.ReadToEndAsync(); } } ``` When I call this method, I'm getting unexpected results. Sometimes the content is truncated or empty. For instance: ```csharp public async Task ProcessFile() { string content = await ReadFileAsync("example.txt"); Console.WriteLine(content); } ``` I've confirmed that the file exists and contains the correct data. I've also tried adding a delay before reading to ensure that the file is fully written by another process, but that didn't help. The code executes without throwing any exceptions, yet the output is inconsistent. I'm using .NET 6.0 and I suspect it might be related to file access permissions or how `StreamReader` handles the file stream asynchronously. Any ideas on why this might be happening or how I can ensure that I read the entire file content reliably? This issue appeared after updating to C# LTS. Am I approaching this the right way?
