Question

I have the following string arrays:

var myArray1 = new string[] {"A", "B", "C"};
var myArray2 = new string[] {"t1", "t2"};

I would like to be able to produce a final string that looks like this:

var myFinalString = "t1.A, t2.A, t1.B, t2.B, t1.C, t2.C";

I know I can iterate through each element of the array and build the string manually. However, I’d like to know if there’s a better way. I tried to figure out how to make String.Join() method work, but couldn’t :-(.

This works:

var query = from x in new[]{"A", "B", "C"}
        from y in new[]{"t1", "t2"}
        select y + "." + x;

var result = string.Join(", ", query.ToArray());
