Why Use the static class in C#

Hello! Pankaj You can use Static class in following scenarion...

1. When you want that instance of class don't be created but this can be also achieved by abstract class but static clsss can't be inherit.... So if you want that instance of class shoudl not be create and class should not be inherit then you can use static class.

2. If you have any concept where you want to declare multiple static fields and methods in that case you can create a static class and put these fields and methods into static class and this class will be work as wraper.

3. A static class can be used as a convenient container for sets of methods that just operate on input parameters and do not have to get or set any internal instance fields
