For and Foreach loop in C#

Hi Vineet,


for loop

The for loop executes a statement or a block of statements repeatedly until a specified expression evaluates to false. The for loop is useful for iterating over arrays and for sequential processing
Because the test of a conditional expression occurs before the execution of the loop, a for statement executes zero or more times.

Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace For_foreach_loop
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i <= 5; i++)
            {
                Console.WriteLine(i);
            }
            Console.ReadLine();
        }
    }
}



For Each loop is used to iterate through arrays or collections.


foreach loop

The foreach statement repeats a group of embedded statements for each element in an array or an object collection. The foreach statement is used to iterate through the collection to get the desired information, but should not be used to change the contents of the collection to avoid unpredictable side effects.

Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace For_foreach_loop
{
    class Program
    {
        static void Main(string[] args)
        {
          

            int[] arr1 = new int[] { 0, 1, 2, 3, 4, 5, 6 };
            foreach (int i in arr1)
            {
                Console.WriteLine(i);
            }
            Console.ReadLine();
        }
    }
}



Thanks
