Our presentation on integration of .NET and Java Web Services was very well received in Dallas and Atlanta symposiums back in November. We will be presenting that at a symposium in Austin in February.

public class Test
{
	public static void call(Test obj)
	{
		new Thread(new Runnable()
		{
			public void run()
			{
				obj.doSomething(); // Perform in a new thread.
			}
		}
		).start();
	}

	public void doSomething() 
	{ // does some thing...
	}
}

In the article "How to create/avoid memory leak in Java and .NET?" we discussed how .NET provides the IDisposable interface as a streamlined standard interface for resource garbage collection. A user of an object should check to see if the class implements the IDisposable interface and then call the Dispose method to release the resources utilized by the object. What keyword does C# provide to help with this process, in a way that this dispose mechanism may be semi automated.

Answer!

The keyword provided in C# for automating the call to Dispose is using. Consider the following code:

public class Test : IDisposable
{
	public void f()
	{
		Console.WriteLine("f called");
	}
	public void Dispose()
	{
		Console.WriteLine("Dispose called");
	}
}

public class User
{
	public static void Main()
	{
		using(Test obj = new Test())
		{
			obj.f();
		}
	}
}
