How to handle disposable objects?

[vyeghikyan-st]

Let us have a class

public class MyClass{
  // Some methods, variables and constructors
  
  public Result<Stream> OpenStream() {
   // Implementation
  }

}

The only pattern I can think of for handling the returned object is as follows:

var instance = new MyClass(..);

var streamReasult = instance.OpenStream();

if(streamResult.IsFailed){
  return Result.Fail<...>(...);
}

try{
  // Do my stuff with the stream
}
finally{
  streamResult.Value.Dispose();
}

Is there a better way?

Apart from the fact that you probably should be using using (var stream = streamResult.Value), your implementation looks correct. Why not use an exception if the stream fails to open, though?
