C# LanguageUsing Statement


Provides a convenient syntax that ensures the correct use of IDisposable objects.


  • using (disposable) { }
  • using (IDisposable disposable = new MyDisposable()) { }


The object in the using statement must implement the IDisposable interface.

using(var obj = new MyObject())

class MyObject : IDisposable
    public void Dispose()
        // Cleanup

More complete examples for IDisposable implementation can be found at the MSDN docs.
