C# has a specialized iteration operator called foreach.
foreach does not loop based on a boolean expression. Rather, it executes a block of code on each element in an array or other collection.

Syntax:

foreach(type loopVariable in collection)
{
    Execution steps
}

In above syntax, the life of loopVariable will be only in the foreach loop.

Since the string array is a valid collection, foreach can be used to iterate through it.

Example:

using System;
 
namespace forgetCode
{
    class Program
    {
        static void Main(string[] args)
        {
 
            string[] cityNames = { "Chennai", "Mumbai", "Bangalore", "Delhi", "Trichy" };
 
            foreach (string name in cityNames)
            {
                Console.WriteLine(name);
            }            
                        
        }
 
    }
}

Output:

Chennai
Mumbai
Bangalore
Delhi
Trichy
