X++ in AX7: Finally and using

Finally, X++ got support for the finally statement. It has exactly the same semantics as in C#. This means that you can now write: 

try 
{
}     
catch 
{
}      
finally 
{
}       

The contents of the finally block is guaranteed to be executed - regardless of exceptions or transactions. It is typically used to clean up any usage of none-managed resources. And to make that construct even cleaner, you can use the using keyword for types implementing the System.IDisposable interface.

using(var myObject = new MyObject()) 
{
    myObject.someMethod();  
}   

This is short hand for:

var myObject = new MyObject();  
try 
{
    myObject.someMethod();  
} 
finally 
{
    myObject.Dispose();  
}  

One more thing…

Just like in C# the using statement can also be used to avoid providing fully qualified names when referencing .NET types. This means I can implement MyObject like this:

using System;  
class MyObject implements IDisposable   
{              
    public void Dispose()
    {
    }
}
