C# Print list of string array

Question

I\'m very new to c# and have a question, how do I print list of string arrays? I can do it from string[] using Console.WriteLine, but if I do that for list with forEach it j

So you have list of string arrays, like this:

 List data = new List() {
   new string[] {"A", "B", "C"},
   new string[] {"1", "2"},
   new string[] {"x", "yyyy", "zzz", "final"},
 };

To print on, say, the Console, you can implement nested loops:

 foreach (var array in data) {
   Console.WriteLine();

   foreach (var item in array) {
     Console.Write(" ");
     Console.Write(item); 
   }
 }

Or Join the items into the single string and then print it:

 using System.Linq;
 ...

 string report = string.Join(Environment.NewLine, data
   .Select(array => string.Join(" ", array)));

 Console.Write(report);

Or combine both methods:

 foreach (var array in data) 
   Console.WriteLine(string.Join(" ", array));
