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

Answer 1

string[] arr = new string[2]{"foo","zoo"}; // sample Initialize.

// Loop over strings.
foreach (string s in arr)
{
    Console.WriteLine(s);
}

The console output:

foo
zoo

Answer 2

In a string array to get the index you do it:

string[] names = new string[3] { "Matt", "Joanne", "Robert" };

int counter = 0;
foreach(var name in names.ToList())
{
 Console.WriteLine(counter.ToString() + ":-" + name);
 counter++;
}

Answer 3

This works for me:

var strArray = new string[] {"abc","def","asd" };
strArray.ToList().ForEach(Console.WriteLine);

Answer 4

Simplest way to achieve this is: using String.Join

string[] arr = new string[] { "one", "two", "three", "four" };
Console.WriteLine(String.Join("\n", arr)); 

Hope this helps.

Answer 5

So you have list of string arrays, like this:

 List<string[]> data = new List<string[]>() {
   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));
