Conditional Using

April 9, 2009

Today I found myself writing the following code:

private void DoSomething(String userName)
{
    using(var userEntry = GetUserEntryFor(userName))
        if(CouldBeFound(userEntry))
    {
        // Do something with userEntry                
    }
} 

private DirectoryEntry GetUserEntryFor(String userName)
{
    // ...        
} 

private static Boolean CouldBeFound(DirectoryEntry entry)
{
     return null != entry;
}

Notice the combination of the if statement with the using statement. I thought this was kind of neat. What do you think?

Is the style of this code bonafide?
