In this article, you will learn what is C# keywords
C# keywords are predefined, reserved identifiers that have special meanings to the compiler. You cannot use it as a variable name, constant name etc.
C# keywords cannot be used as identifiers in your program unless they include @ as a prefix.

| continue | decimal | default | delegate |

| struct | switch | this | throw |
| true | try | typeof | uint |
| ulong | unchecked | unsafe | ushort |
| using | virtual | void | volatile |

Contextual keywords in c# have special meaning only in a limited program context and can be used as identifiers outside that context. In General, as new keywords are added to the C# language, they are added as contextual keywords in order to avoid breaking programs written in earlier versions.

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.
