Concatenate two Dictionaries
c#, implicit-conversion
Solution
I think you defined your `GroupNames` as `Dictionary<string,string>`, so you need to add `ToDictionary` like this:
GroupNames = GroupNames.Concat(AddedGroupNames)
.ToDictionary(x=>x.Key,x=>x.Value);
Note that 2 original dictionaries would have different keys, otherwise we need some rule to merge them correctly.
Problem
Given some Dictionaries ``` Dictionary<string, string> GroupNames = new Dictionary<string, string>(); Dictionary<string, string> AddedGroupNames = new Dictionary<string, string>(); ``` I am unable to merge them into one: ``` GroupNames = GroupNames.Concat(AddedGroupNames); ``` because "the type can't be implicitly converted". I believe (and my code proves me true) their type is the same - what am I overlooking?
