C#

List<projectcounterentities> lstResult = new List<projectcounterentities>();
List<dictionary><projectstates,string>> lstProjectCount = new List<dictionary><projectstates,string>>();
lstProjectCount = objClient.GetProjectCounter();
if (lstProjectCount != null)
{
    var dicResult = new Dictionary<projectstates,string>();
    dicResult = lstProjectCount.ToDictionary();
    foreach (var k in dicResult)
    {
        objProCount = new ProjectCounterEntities();
        objProCount.ProjectState = (ProjectStateEnumUI)k.Key;
        objProCount.ProjectCount = k.Value;
        lstResult.Add(objProCount);
    }
    return lstResult;
}

I want to retrive value with respact to key , and want to map the value and key both into the DTO List<projectcounterentities>, where ProjectCounterEntities is a DTO and the members of this DTO are "ProjectState" and "Count".

The output of List<projectcounterentities> will be

ProjectState       Count
------------------------ 
projectstate1      2
Projectstate2      5
ProjectState3      6

I've got not an exact answer, but suggestion... You can easily get count of projectstates by using Linq.

Have a look here:

Hi once try this code
i created enum and class which is having two properties

public enum projectstates
   {
       projectstate1 = 1,
       projectstate2 = 2,
       projectstate3 = 3,
       projectstate4 = 4
   }

   public class projectcounterentities
   {
       public string ProjectState { get; set; }
       public string count { get; set; }
   }



 List<dictionary><projectstates,>> list = new List<dictionary><projectstates,>>()
           {
               new Dictionary<projectstates,>() { { projectstates.projectstate1, "3" }, { projectstates.projectstate3, "75" } },
               new Dictionary<projectstates,>() { { projectstates.projectstate4, "3" }, { projectstates.projectstate2, "15" } }
           };

           List<projectcounterentities> projectcounterentities = new List<projectcounterentities>();

           foreach (var item in list)
           {
               projectcounterentities.AddRange(item.Select(h => new projectcounterentities() { count = h.Value, ProjectState = h.Key.ToString() }));
           }
