           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ASHA", Count = "10", MonthYear = "Sep-2015" });

           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "March-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Feb-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Jan-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Dec-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Nov-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Oct-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "MOTHER", Count = "10", MonthYear = "Sep-2015" });

           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "March-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Feb-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Jan-2016" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Dec-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Nov-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Oct-2015" });
           listStateViewBenWise.Add(new StateViewBenWise() { BenType = "ANM", Count = "10", MonthYear = "Sep-2015" });


foreach (List<StateViewBenWise> itemBenType in listStateViewBenWise.GroupBy(x => x.BenType))

I want output in itemBenType first time all ASHA then MOTHER then ANM

What I have tried:

foreach (List<stateviewbenwise> itemBenType in listStateViewBenWise.GroupBy(x => x.BenType))

need to use Yield

I don't think you want to use yield unless you've not mentioned your full requirements.

Solution 1

You probably want something like this (accessing the values here is meant just for demonstration of course):

C#

foreach (var grouping in listStateViewBenWise.GroupBy(x => x.BenType))
{
   string benType = grouping.Key; // valid for all items below:
   foreach (StateViewBenWise item in grouping)
   {
      string count = item.Count;
      string monthYear = item.MonthYear;
   }
}

Solution 3

Try this

C#

List<StateViewBenWise> CompleteList = new List<StateViewBenWise>();

           var groupingResult = listStateViewBenWise.GroupBy(k => k.BenType);
           foreach (var grouping in groupingResult)
           {
               string benchType = grouping.Key;
               List<StateViewBenWise> eachGroupResult  = grouping.ToList();
               CompleteList.AddRange(grouping);
           }
