Question

Have an object which is an array (not arraylist or generic) that could hold a set of anything…

[[One],[Two],[Three],[Four]] 

Want to move [Four] to in front of [Two] e.g. oldIndex = 3, newIndex = 1 so the result would be…

[[One],[Four][Two],[Three]] 

Whats the most effient way to do this in .NET 2.0, e.g.

PropertyInfo oPI = ObjectType.GetProperty('MyArray', BindingFlags.Public | BindingFlags.Instance); object ObjectToReorder = oPI.GetValue(ParentObject, null); Array arr = ObjectToReorder as Array; int oldIndex = 3; int newIndex = 1; //Need the re-ordered list still attached to the ParentObject 

thanks in advance

Answer 1

void MoveWithinArray(Array array, int source, int dest) {   Object temp = array.GetValue(source);   Array.Copy(array, dest, array, dest + 1, source - dest);   array.SetValue(temp, dest); }
