Hi Gantasala, The static keyword is used to specify a static member, which means static members are common to all the objects. This keyword can be used with classes, fields, methods, properties, operators, events, and constructors, but it cannot be used with indexers, destructors, or types other than classes. Finally i understand the static variable.....static variable shared the value of it among all instances of the class. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication2 { class Program { static int a; // initialized at the time of declaration public static int Hello() { a = 20; return a; } } class run { static void Main( string [] args) { //Program p = new Program(); Console .WriteLine( Program .Hello()); } } } Output 20 More details checkout below links http://www.c-sharpcorner.com/UploadFile/rohatash/const-readonly-and-static-keywords-in-C-Sharp/ http://www.c-sharpcorner.com/Blogs/13039/static-keyword-in-C-Sharp.aspx https://msdn.microsoft.com/en-in/library/98f28cdx.aspx

Main method is the necessary entry point for any "Executable" and it must be Static because that is required in order to access the method without having an instance of the object to address. In order to invoke the method from outside the application, a static method is required. Please refer https://msdn.microsoft.com/en-us/library/acy3edy3.aspx hope this will help you.
