I'd like to know how to Count the instances of the first element in a list, then the second etc. and output these values.
var SPFK_List = new List<string>() { "one", "one", "one", "two", "two", "three", "three", "three" }; Inputs.ones.Value = *(number of one's)* Inputs.twos.Value = *(number of two's)* Try GroupBy (Linq), e.g.:
using System.Linq; ... var SPFK_List = new List<string>() { "one", "one", "one", "two", "two", "three", "three", "three" }; // {3, 2, 3} int[] counts = SPFK_List .GroupBy(item => item) .Select(group => group.Count()) .ToArray(); Or (add Where if you want to count only some items)
// {{"one", 3}, {"two", 2}, {"three", 3}} Dictionary<string, int> counts = SPFK_List //.Where(item => item == "one" || item == "two") .GroupBy(item => item) .ToDictionary(group => group.Key, group => group.Count()); Inputs.ones.Value = counts.TryGetValue("one", out int count) ? count : 0; 
A possible solution:
Inputs.ones.Value = SPFK_List.Where(x => x.Equals("one")).Count(); 
Simply use Count method from System.Linq with overload accepting a Func<TSource,bool> predicate
var SPFK_List = new List<string>() { "one", "one", "one", "two", "two", "three", "three", "three" }; Inputs.ones.Value = SPFK_List.Count(s => s.Equals("one", StringComparison.Ordinal)); Inputs.twos.Value = SPFK_List.Count(s => s.Equals("two", StringComparison.Ordinal));
Inputs.first.Value = List.Where(x => x.Equals(Distinct_List[2])).Count();Where the distinct list is a list of added distinct values from the first list.
