implementing IDisposable in C# when using Streams and Custom Classes for Resource Management
I'm working with a question with the implementation of IDisposable in my custom class that handles file streams. I have a class `FileStreamHandler` that opens a file stream, performs some operations, and should release the resources correctly. However, I'm experiencing unexpected behavior when disposing of the object. Specifically, I'm getting a `ObjectDisposedException` when trying to read from the stream after calling `Dispose()`, even though I believe I've implemented the IDisposable pattern correctly. Here's my implementation: ```csharp public class FileStreamHandler : IDisposable { private FileStream _fileStream; private bool _disposed = false; public FileStreamHandler(string filePath) { _fileStream = new FileStream(filePath, FileMode.Open); } public void ReadData() { if (_disposed) throw new ObjectDisposedException("FileStreamHandler"); // Assume some logic to read data from stream byte[] buffer = new byte[1024]; _fileStream.Read(buffer, 0, buffer.Length); } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { if (!_disposed) { if (disposing) { // free managed resources _fileStream?.Dispose(); } // free unmanaged resources if any _disposed = true; } } } ``` After creating an instance of `FileStreamHandler`, I call `ReadData()` multiple times without scenario, but once I call `Dispose()`, any subsequent calls to `ReadData()` throw an `ObjectDisposedException`, which I expected. However, I noticed that if I wrap the `ReadData()` call in a try-catch block, I'm sometimes still able to get a few reads before it fails. I've also tried implementing a `using` statement, but it behaves the same way. Am I missing something in handling the disposal of the stream, or is there a better pattern I should be following for resource management? Any help would be appreciated!
