C# Print list of string array

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 just prints out System.String[], how do I write index when using for each?

  if you want to print array values, you cannot just pass array to Console.WriteLine you should either print each item of array separately or convert array to string and then print that string. E.g. with String.Join(",", yourArray)

Simplest way is this:
using String.Join

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

Hope this helps.

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));

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++;

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++;
