Ich verwende den Dynamic Linq-Helfer zum Gruppieren von Daten. Mein Code lautet wie folgt:

Employee[] empList = new Employee[6];
empList[0] = new Employee() { Name = "CA", State = "A", Department = "xyz" };
empList[1] = new Employee() { Name = "ZP", State = "B", Department = "xyz" };
empList[2] = new Employee() { Name = "AC", State = "B", Department = "xyz" };
empList[3] = new Employee() { Name = "AA", State = "A", Department = "xyz" };
empList[4] = new Employee() { Name = "A2", State = "A", Department = "pqr" };
empList[5] = new Employee() { Name = "BA", State = "B", Department = "pqr" };

var empqueryable = empList.AsQueryable();
var dynamiclinqquery  = DynamicQueryable.GroupBy(empqueryable, "new (State, Department)", "it");

Wie kann ich den Schlüssel und die entsprechende Liste der gruppierten Elemente, d. H. Die Anzahl der {Schlüssel, Liste}, von dynamiclinqquery zurückerhalten?
