                string text = Session["CAPTCHA"].ToString();
                //first, create a dummy bitmap just to get a graphics object
                Image img = new Bitmap(1, 1);
                Graphics drawing = Graphics.FromImage(img);
                Font font = new Font("Arial", 15);
                //measure the string to see how big the image needs to be
                SizeF textSize = drawing.MeasureString(text, font);
                //free up the dummy image and old graphics object
                //create a new image of the right size
                img = new Bitmap((int)textSize.Width + 40, (int)textSize.Height + 20);
                drawing = Graphics.FromImage(img);

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.
