Create duplicate items in a list

Question

I have the following code to duplicate the members of a list X times.

Although it works it doesn\'t feel particularly clean.

Live code example:

Answer 1

Perhaps something along the lines of:

var serviceEndPoints = splitEndPoints.SelectMany(t =>
    Enumerable.Repeat(t, instances)).ToList();

That will give you "A,A,A,B,B,B,C,C,C". If you want "A,B,C,A,B,C,A,B,C":

var serviceEndPoints = Enumerable.Repeat(
    splitEndPoints, instances).SelectMany(t => t).ToList();
