Rajeesh Menoth · Answer

Hi Pramod We can access all static method without the creation of objects. Code : using System; public class Program { static string str = Hello World !! ; public static class Test { public static string Message() { return str; } } public static void Main() { Console.WriteLine(Program.Test.Message()); } } Demo : https://dotnetfiddle.net/W5CExd

Why to use static class? If there is a requirement that we don’t need to create the instance of the class but we want to access their class members then we create class as static.

When we want to share only one instance of the class with all which means that every time that class is accessed there is only one instacne behind the scenes that is used it is useful when we create helper classes that contain methods which will be used in different parts of application. Consider Convert class in .NET base class libraries it contains different kind of methods to convert a particular string to integerfloat decimal etc it is static becasue nobody would need to create it's instances it has common funcationality which is used by callers at different parts of their application code. The following post explains it very well why to use static http://softwareengineering.stackexchange.com/questions/103914/why-and-when-should-i-make-a-class-static-what-is-the-purpose-of-static-key Hope that helps to understand why we need and where they are useful :)
