Hi, Here it is // keywords_this.cs // this example using System; public class Employee { public string name; public string alias; public decimal salary = 3000.00m; // Constructor: public Employee(string name, string alias) { // Use this to qualify the fields, name and alias: this.name = name; this.alias = alias; } // Printing method: public void printEmployee() { Console.WriteLine("Name: {0}
Alias: {1}", name, alias); // Passing the object to the CalcTax method by using this: Console.WriteLine("Taxes: {0:C}", Tax.CalcTax(this)); } } public class Tax { public static decimal CalcTax(Employee E) { return (0.08m*(E.salary)); } } public class MainClass { public static void Main() { // Create objects: Employee E1 = new Employee ("John M. Trainer", "jtrainer"); // Display results: E1.printEmployee(); } } Regards, Iftikar

Simple explanation of this keyword to make user understand its way of using and implementation. The this keyword refers to the current instance of the class. It can be used to access members from within constructors, instance methods, and instance accessors. Static constructors and member methods do not have a this pointer because they are not instantiated. When you are writing code in method or property of a class, using " this " will allow you to make use of the intellisense. this keyword is used when you want to track the instance, which is invoked to perform some calculation or further processing relating to that instance. for example check this link http://www.c-sharpcorner.com/uploadfile/puranindia/this-keyword-in-C-Sharp/
