In this article, you will learn what is C# tuple
C# tuple is a data structure that is used to store sequence of elements. It can be used where you want to have a data structure to hold an object with properties, but you don't want to create a separate type for it. The Tuple<T>
class was introduced in .NET Framework 4.0.
using System;
namespace USINGCSHARP
{
class TupleEx
{
public static void Main(string[] args)
{
// Creating Tuple of three values
var book = new Tuple<string, string, double>("C# in tuple", "Delhi", 1000);
Console.WriteLine("Name" + book.Item1);
Console.WriteLine("City" + book.Item2);
Console.WriteLine("Price " + book.Item3);
}
}
}
In the following example, we are using create method.
using System;
namespace usingcsharp
{
class TupleEx
{
public static void Main(string[] args)
{
var tp = Tuple.Create("C# in tuple", "Delhi", 1000);
Console.WriteLine("Name " + tp.Item1);
Console.WriteLine("City " + tp.Item2);
Console.WriteLine("Price " + tp.Item3);
}
}
}
Example: Nested Tuple
var numbers = Tuple.Create(1, 2, 3, 4, 5, 6, 7, Tuple.Create(8, 9, 10, 11, 12, 13));
numbers.Item1;
numbers.Item7;
numbers.Rest.Item1;
numbers.Rest.Item1.Item1;
numbers.Rest.Item1.Item2;
Output
1
7
(8, 9, 10, 11, 12, 13)
8
9
A Tuple can be return from a method.
static void Main(string[] args)
{
var details = Bind();
}
static Tuple<int, string, string> Bind()
{
return Tuple.Create(100, "Delhi", "NCR");
}
You can define tuples with an arbitrary large number of elements:
var tp =
(1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18,
19, 20, 21, 22, 23, 24, 25);
Console.WriteLine(tp.Item25); // output: 25

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.

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.
