Merging dictionaries in C#
- by orip
What's the best way to merge 2 or more dictionaries (Dictionary<T1,T2>) in C#?
(3.0 features like LINQ are fine).
I'm thinking of a method signature along the lines of:
public static Dictionary<TKey,TValue>
Merge<TKey,TValue>(Dictionary<TKey,TValue>[] dictionaries);
or
public static Dictionary<TKey,TValue>
Merge<TKey,TValue>(IEnumerable<Dictionary<TKey,TValue>> dictionaries);
EDIT: Got a cool solution from JaredPar and Jon Skeet, but I was thinking of something that handles duplicate keys. In case of collision, it doesn't matter which value is saved to the dict as long as it's consistent.
