POC# - Syntactic sugar for out parameters?
text
Body
copied!<p>Let us say for a moment that C# allowed multiple return values in the most pure sense, where we would expect to see something like:</p> <pre><code>string sender = message.GetSender(); string receiver = message.GetReceiver(); </code></pre> <p>compacted to:</p> <pre><code>string sender, receiver = message.GetParticipants(); </code></pre> <p>In that case, I do not have to understand the return values of the method until I actually make the method call. Perhaps I rely on Intellisense to tell me what return value(s) I'm dealing with, or perhaps I'm searching for a method that returns what I want from a class I am unfamiliar with.</p> <p>Similarly, we have something like this, currently, in C#:</p> <pre><code>string receiver; string sender = message.GetParticipants(out receiver); </code></pre> <p>where the argument to GetParticipants is an <strong>out</strong> string parameter. However, this is a bit different than the above because it means I have to preempt with, or at least go back and write, code that creates a variable to hold the result of the out parameter. This is a little counterintuitive.</p> <p>My question is, is there any syntactic sugar in current C#, that allows a developer to make this declaration in the same line as the method call? I think it would make development a (tiny) bit more fluid, and also make the code more readable if I were doing something like:</p> <pre><code>string sender = message.GetParicipants(out string receiver); </code></pre> <p>to show that receiver was being declared and assigned on the spot.</p>
