In this article, you will learn what is C# foreach loop (With Example)

In this article, how to use foreach loop in c#.

Syntax of foreach loop

foreach (element in item)
{
    // body of foreach loop
}

The foreach statement executes a statement or a block of statements for each element in an instance of the type that implements the System.Collections.Generic.IEnumerable<T> or System.Collections.IEnumerable interface, as the following example:

var numbers = new List<int> { 0, 1, 1, 2, 3, 5, 8, 17 };
int count = 0;
foreach (int element in numbers )
{
    count++;
    Console.WriteLine($"Element #{count}: {element}");
}
Console.WriteLine($"Number of elements: {count}");

Foreach loop with List (Collection)

using System;
using System.Collections.Generic;
 
namespace UsingCsharp
{
    class ForEachLoop
    {
        public static void Main(string[] args)
        {
            var numbers = new List() {1,3,2,9,6,0,5};
            int sum = 0;
 
            foreach(int number in numbers)
            {
                sum += number;
            }
            Console.WriteLine("Sum = {0}", sum);
        }
    }
}

Output

Sum = 26

Printing array using foreach loop

using System;
 
namespace Loop
{
    class ForEachLoop
    {
        public static void Main(string[] args)
        {
            char[] myArry = {'U','s','i','n','g','c','s','h','a','r','p'};
 
            foreach(char ch in myArry )
            {
                Console.WriteLine(ch);
            }
        }
    }
}

Output

U

s

i

n

g

c

s

h

a

r

p

C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application. C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming and will also take you through various advanced concepts related to C# programming language. C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc. For example... using System; namespace MinifyCode { class Program { static void Main(string[] args) { Console.WriteLine("Hello Minify Code"); } } } Output: Hello Minify Code In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object. Session Application Cache Request Response Server User Trace Server Object The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs. Methods and Properties of the Server object The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Optimization; using System.Web.Routing; using System.Web.Security; using System.Web.SessionState; using System.Data.Entity; namespace minifycode { public class Global : HttpApplication { void Application_Start(object sender, EventArgs e) { // Code that runs on application startup RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); // Initialize the product database.
