I want to use Dictionary class like this:
textboxM.Text = oMyDict.GetValue("textboxM");
textboxN.Text = oMyDict.GetValue("textboxN");
Where my dictionary contains the list of values for my textbox based on
the textbox id.
But it doesn't have it !
Use the indexer
textboxM.Text = oMyDict["textboxM"];
TryGetValue !? What's that ? Why I have to provide an out parameter,
isn't more simple just return the value or null if not found !?
A Dictionary can be instantiated with a value type that isn't
nullable, so returning null isn't always an option. That's why
TryGetValue is needed.
