Just sharing a sample code to remove duplicates from a list using linq
public class MyClass
{
public string ID { get; set; }
public string Value { get; set; }
}
List<MyClass> myList = new List<MyClass>();
var xrmOptionSet = new MyClass();
xrmOptionSet.ID = "1";
xrmOptionSet.Value = "100";
var xrmOptionSet1 = new MyClass();
xrmOptionSet1.ID = "2";
xrmOptionSet1.Value = "200";
var xrmOptionSet2 = new MyClass();
xrmOptionSet2.ID = "1";
xrmOptionSet2.Value = "100";
myList.Add(xrmOptionSet);
myList.Add(xrmOptionSet1);
myList.Add(xrmOptionSet2);
// here we are first grouping the result by label and then picking the first item from each group
var myDistinctList = myList.GroupBy(i => i.ID)
.Select(g => g.First()).ToList();
Hope it helps..
