Hi All, I have a generic List property in my class called Data and depending on certain conditions want to apply a groupby at the end of processing, this is how I currently do it and it works fine.

if(SomeCondition)
    Data = Data.GroupBy(g => g.Destination).Select(s => s.First()).ToList();
else
    Data = Data.GroupBy(g => g.DialCode).Select(s => s.First()).ToList();

// Is there a way I can define a Func<> or something to replace this ?

Func< "What do I put here"> grouper = "What do I put here";
// so I can say

Data = Data.GroupBy(grouper).Select(s => s.First()).ToList();
