C# get the types defining a Dictionary at run time

Question

I was wondering what is the best way for getting the generic arguments that definine a dictionary at run time is.

Take for example:

Dictionary<string, object> dict;

How at runtime can I find out that the keys are strings?

Answer 1

I'm not sure if I understand your question correctly but I think you mean something like this:

Dictionary<string, object> dict = new Dictionary<string, object>();
// ...
var args = dict.GetType().GetGenericArguments();
// args[0] will be typeof(string)
