User kokos answered the wonderful Hidden Features of C# question by mentioning the using keyword. Can you elaborate on that? What are the uses of using?
The Using scope modifier is supported in the following contexts: Remotely executed commands, started with Invoke-Command using the ComputerName, HostName, SSHConnection or Session parameters (remote session) Background jobs, started with Start-Job (out-of-process session) Thread jobs, started via Start-ThreadJob or ForEach-Object -Parallel ...
183 In C++11, the using keyword when used for type alias is identical to typedef. 7.1.3.2 A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name.
48 Justin Lessard's answer explains the difference between using and await using, so I'll focus on which one to use. There are two cases: either the two methods Dispose / DisposeAsync are complementary, or they are doing something different.
Yes Yes. Either way, when the using block is exited (either by successful completion or by error) it is closed. Although I think it would be better to organize like this because it's a lot easier to see what is going to happen, even for the new maintenance programmer who will support it later:
Updating the using keyword was specifically for templates, and (as was pointed out in the accepted answer) when you are working with non-templates using and typedef are mechanically identical, so the choice is totally up to the programmer on the grounds of readability and communication of intent.
By using a joystick or a pointing device, an on-screen keyboard allows people with mobility impairments to type data. The second sentence states that the on-screen keyboard is the one that uses the joystick or pointing device to allow impaired people to type data.
The using statement is used to work with an object in C# that implements the IDisposable interface. The IDisposable interface has one public method called Dispose that is used to dispose of the object.
With could work, but it sometimes connotes along with, as in with a companion, which is not the case. Using is the best bet, since that connotes using a tool, which is what we want. Also, do exploration is clunky, and sounds wrong. Explore means the same thing, but sounds much more natural: Explore using Mobile Robot.
