How to splice two C# lists into one? Or maybe use a different collection type?

List<string> list1 = new List<string>();
list1.Add("Blah");
list1.Add("Bleh");
list1.Add("Blih");

List<string> list2 = new List<string>();
list2.Add("Ooga");
list2.Add("Booga");
list2.Add("Wooga");

Is there a method to create a third list that has {"Blah", "Bleh", "Blih", "Ooga", "Booga", "Wooga"} or, alternatively, change list1 so it has the three additional elements in list2?

With LINQ, you can do:

List<string> list1 = new List<string>();
list1.Add("Blah");
list1.Add("Bleh");
list1.Add("Blih");

List<string> list2 = new List<string>();
list2.Add("Ooga");
list2.Add("Booga");
list2.Add("Wooga");

var finalList = list1.Concat( list2 ).ToList();

Take a look at the Union() method of a List.

I guess this is the solution:

list1.AddRange(list2)
