C# convert an IOrderedEnumerable<KeyValuePair<string, int>> into a Dictionary<string, int>
- by Kache4
I was following the answer to another question, and I got:
// itemCounter is a Dictionary<string, int>, and I only want to keep
// key/value pairs with the top maxAllowed values
if (itemCounter.Count > maxAllowed) {
IEnumerable<KeyValuePair<string, int>> sortedDict =
from entry in itemCounter orderby entry.Value descending select entry;
sortedDict = sortedDict.Take(maxAllowed);
itemCounter = sortedDict.ToDictionary<string, int>(/* what do I do here? */);
}
Visual Studio's asking for a parameter Func<string, int> keySelector. I tried following a few semi-relevant examples I've found online and put in k => k.Key, but that gives a compiler error:
'System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string,int>>'
does not contain a definition for 'ToDictionary' and the best extension method overload
'System.Linq.Enumerable.ToDictionary<TSource,TKey>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource,TKey>)'
has some invalid arguments
