[ StackOverflow ] – Use ListForEach to add element to HashTable

c# – Use ListForEach to add element to HashTable – Stack Overflow

Try this:

valueList.ForEach(x => htable.Add(valueList.FindIndex(y => y == x), x));

Although, there’s really no reason not to use a for here

for(var index =0; index < valueList.Count; index++){
    htable.Add(index, valueList[index]);}
