存储GUID和DateTime对象列表的最佳方法

Question

I need to store a C# list of pair values GUID and Datetime.

The list will be static and I wanted to be able to quickly retrieve the existence of a GUID value so speed is essential.

What's the best alternative between list, dictionary or any other searchable collection for GUID's keys?

Answer 1

I'd just use a Dictionary<Guid, DateTime> . I'd be surprised if there was any major performance difference between using a dictionary or list, for example. I'd see how the dictionary performs and then try something else if you're finding it slow before trying to micro-optimize before you even know if it'll be a problem.

Based on experience, Dictionary<TKey, TValue> is all around the fastest/easiest way.
