Question

I have a series of Read() overloads in a class.
Each opens the file only long enough to read, so I have:

public void Read(blah)
{
    using (FileStream stream = new FileStream(Path, FileMode.Open, FileAccess.Read))
    using (BinaryReader reader = new BinaryReader(stream))
    {
        //read some stuff        
    }
}

public void Read(blah blah)
{
    using (FileStream stream = new FileStream(Path, FileMode.Open, FileAccess.Read))
    using (BinaryReader reader = new BinaryReader(stream))
    {
        //read some different stuff        
    }
}

Is there any way of wrapping the stream and reader creation in a function, and yet still retain the using() to dispose everything automatically?
eg

public void Read(blah)
{
    using (var reader = GetReader())
    {
        //read some stuff        
    }
}

public void Read(blah blah)
{
    using (var reader = GetReader())
    {
        //read some different stuff        
    }
}

private BinaryReader GetReader()
{
    //How do I dispose this stream?
    FileStream stream = new FileStream(Path, FileMode.Open, FileAccess.Read))

    return new BinaryReader(stream);
}

Answer 1

In this specific case, you don’t have to dispose your stream. Upon disposal, the BinaryReader will automatically dispose the underlying stream.

But maybe the BinaryReader is just an example?
