How can I merge more than two lists together in Xamarin forms? I use concat now but that only allows me to add two list into one

Question

I am using using concat right now to merge lists together but that only allows me to merge two lists together but when I try to merge a third list together it doesnt allow me to do that with my code below.

    new List <items> theListOne = new List <items> ();
    new List <items> theListTwo = new List <items> ();
    new List <items> theListThree = new List <items> ();

    var result = theListOne.Concat(theListTwo).ToList();

If I want more than two lists together, how would i solve that?

You can concat as many enumerables as you want

var result = theListOne.Concat(theListTwo).Concat(theListThree)....ToList();

Make sure to use ToList() only once at the end to avoid useless enumerations
