Are those 20 values so far in that list are in increasing order or in random sequence?

Solution 1

If list has values in increasing order then you can do something like this:

C#

int lastVal = AncillariesList[AncillariesList.Count - 1];

now while adding new member, you can use

C#

++lastVal;

int lastVal = AncillariesList[AncillariesList.Count - 1]; This says cannot implicitly convert type controlDomain to int.

This must be returning some class object.
Use classobject.Lineno property.
For e.g: AncillariesList[AncillariesList.Count - 1].Lineno;
