Hi,
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. For example, in the .NET Framework Class Library, the static System.Math class contains methods that perform mathematical operations, without any requirement to store or retrieve data that is unique to a particular instance of the Math class. That is, you apply the members of the class by specifying the class name and the method name, as shown in the following example.

double dub = -3.14;

Console.WriteLine(Math.Abs(dub));

Console.WriteLine(Math.Floor(dub));

Console.WriteLine(Math.Round(Math.Abs(dub)));

// Output:

// 3.14

// -4

// 3

As static members know nothing about particular instances of a class - they apply to the class as a whole - it makes sense that they should be called with the class name rather than with an instance variable.
