Question

Out style:

bool result; if(something.TryParse(val, out result)) {     DoSomething(result); } 

Nullable style:

bool? result = something.TryParse2(val); if(result.HasValue) {     DoSomething(result.Value); } 

Answer 1

TryParse(val, out result) is a idiom established by the .NET framework in int.TryParse, DateTime.TryParse, etc. It is likely that people that read the code will be familiar with this idiom, so you should stick to it, unless you find a very good reason not to.
