Quick C# Help Retrieve data using while (!sr.EndOfStream)

Question

I ran into problem for my school assignment and it is to display whatever in a meal.csv file, here is a code we are starting with. The array string of itemDetails is where the data is store then passed into array ReadLines, then in Main, it is passed to mealContent, but when I tried Console.WriteLine(mealContent); it only prompted System.String[]. So how do I at least display it out in the command prompt. Thanks for the help guys~ Source code is also attached

          int totalItems  = GetLineCount();

          string[] itemDetails = new string[totalItems];

          StreamReader sr = new StreamReader(FileLocation.INPUT_FILE);

 

          string itemDetail;

          int counter = 0;

 

            while (!sr.EndOfStream){

                itemDetail = sr.ReadLine();

                if (itemDetail.Trim() != "")

                    itemDetails[counter++] = itemDetail;
