Easy way to Populate a Dictionary<string,List<string>>
- by zion
Greetings Guru's, my objective is to create a Dictionary of Lists, does a simpler technique exist?
I prefer the List(t) to IEnumerable(t) which is why I chose the Dictionary of Lists over Ilookup or IGrouping.
The code works but it seems like a messy way of doing things.
string[] files = Directory.GetFiles (@"C:\test");
Dictionary<string,List<string>> DataX = new Dictionary<string,List<string>>();
foreach (var group in files.GroupBy (file => Path.GetExtension (file)))
{
DataX.Add (group.Key, group.ToList());
}
