reshuffle collection with linq

Question

Hi,

I have a collection of numbers starting from 1-9. I would like to reshuffle the collection so that the first object in the collection is 6 and everything before 6 is appended to the end of the list e.g. if if the first object is 3 than the collection would look like this: 345678912.

How can i do this using C# and linq?

Any help would be greatly appreciated.

Answer 1

Something like:

return items.Skip(6).Concat(items.Take(6));

Where items is your collection and 6 is the number of items you want to move to the end.

Answer 2

Try:

var coll = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

var shuffle = coll.SkipWhile( x => x != 6 )
                  .Concat( coll.TakeWhile( x => x != 6 ) )
                  .ToArray(); // converting to an array is optional....

// result: 6, 7, 8, 9, 1, 2, 3, 4, 5
