One of the many benefits of high security keys like restricted keys, is that they’re hard to duplicate! That’s because restricted keys generally have patents or other qualities that require only approved manufacturers to produce. Restricted keys are the variety that you should obtain permission to duplicate. It also depends on the locksmith and how comfortable they are with accepting the request. In fact, one is actually perfectly okay to duplicate. ![]() We say that it depends because there are two types of do not duplicate keys and one is much easier to get away with copying than the other. Is it purely a suggestion? Could I really get into trouble for this? As it pertains to keys, the answer is that it depends. ![]() Public static bool TryAdd(this IDictionary dictionary, Func keyFunc, Func valueFunc) =>ĭictionary.Knowing whether or not you’re in the clear to make a copy of a “do not duplicate” key feels a lot like deciding if it’s truly illegal to take the tags off your mattress. Public static bool TryAdd(this IDictionary dictionary, TKey key, Func valueFunc) => Public static bool TryAdd(this IDictionary dictionary, Func keyFunc, TValue value) => If (dictionary?.ContainsKey(key) = false) Public static bool TryAdd(this IDictionary dictionary, TKey key, TValue value) public static class IDictionaryExtensions To that end, here's a very small extension method class that a) uses IDictionary rather than Dictionary to develop to interfaces rather than implementations, b) adds generics to the mix rather than the int and string concretions, c) returns a bool in the case you need to know if a the add made it in or not, d) utilizes overloads such that either the key and value may be used directly, or any mixture of Funcs that return those parameters can be used. different key or value types in a different dictionary, or maybe even a different dictionary class altogether) and rather than re-writing every instance where the pattern is used, you'll want to DRY (don't repeat yourself) your code out to have a minimal, well-tested area where this particular functionality and behavior resides. Where you already have had for years excellent answers on what the idiomatic best practice is for the given use case, as a developer you will often find yourself needing to tweak that code somewhat in different situations (e.g. The dictionaries are relatively small (typically < 1000 entries) so I prefer readability over performance. public void AddToDictionaryTr圜atch(Dictionary myDictionary, int myKey, string myValue) The advantage is that if I ever do decide to log the problem I have a place to do it. Maybe a try/catch block - but this seems less readable. public void AddToDictionar圜ontainsKey(Dictionary myDictionary, int myKey, string myValue ) I find myself using this pattern frequently but wonder if there is a better way. I'd like to say that I can always guarantee uniqueness upstream, but I'm dealing with legacy code and mildly corrupt data from an old bug in the system. What is the cleanest way to use dictionaries and protect against an unhandled ArgumentException if the key already exists in the dictionary?
