Let’s say I have a

public class MyObject
{
   public string Property1;
   //other properties
   //other properties
}

and then I have a 

List<MyObject> objectList

Where Property1 has one value for the first few items, another value for the next few items, etc. How can I count the distinct number of MyObjects based on Property1?

    Use GroupBy. 

    objectList.GroupBy(o => o.Property1);
