Retrieving Dictionary Value Best Practices

Question

I just recently noticed Dictionary.TryGetValue(TKey key, out TValue value) and was curious as to which is the better approach to retrieving a value from the Dic

Answer 1

I imagine that trygetvalue is doing something more like:

if(myDict.ReallyOptimisedVersionofContains(someKey))
{ 
  someVal = myDict[someKey];
  return true;
}
return false;

So hopefully no try/catch anywhere.

I think it is just a method of convenience really. I generally use it as it saves a line of code or two.
