Foreach Loop in C#

Foreach Loop in C#:-

It is the special loop in C# that is used to display the array elements specially, It is the modified form of for loop.

Syntax of foreach

foreach(var in arrayvar1)
{
         Statements;
}

Example of Foreach Loop Based Program in C#:-

 class ObjectArr
    {
        static void Main()
        {
           // object [] arr = {"C","CPP",1200,12.34F,true,'a' };
            int[] arr = { 12, 23, 11, 45, 67 };
            foreach (int a in arr)
            {
                Console.WriteLine(a);
            }
}

Another Example of Foreach Loop to Display Elements?

using System;

class ForeachDemo

{

   static void Main()

   {

        int [] arr = {12,23,47,89,11,77};

        foreach(int k in arr)

        {

              Console.WriteLine(k);

        }

       object [] o = {"C",123,"C++",true,12.34F};

       foreach(object o1 in o)

       {

          Console.WriteLine(o1);

       }

   }

}

Nested Foreach Loop:-

We can create more than one foreach loop using nested sequence, it is used to display multidimensional array or Jagged Array.

Example of Multidimensional Foreach Loop

using System;

class ForeachDemo

{

   static void Main()

   {

     int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };

     foreach (int[] subArray in array) {

    foreach (int i in subArray) {

        Console.Write(i);

    }

}

    

   }

}
