Return Anonymous Type from a function

Question

Can I use an anonymous type as a return type in a Function, and then stuff that returned value into an array or collection of some sort whilst also adding an additional fiel

Answer 1

Use object, not var. You'll have to use reflection to access the properties outside the scope of the anonymous type though.

i.e.

private object GetRowGroups(string columnName) 
...
var RowGroupList = new List
