How to call a class in main class without creating an object ? in "c# language".?

Question

see, if i have more than two classes other than main class how should i call it in main func (or) class without creating an object?

Answer 1

If the method of your class is static, you can invoke it directly by calling classname.Method(); otherwise you will need to instantiate the class.

Answer 2

Through using static classes or static methods. Following an example of how you do it:
public static class Utilities
{

public static void MyMethod()
{
// do stuff here

}
}
// --- calling the method.
Utilities.MyMethod();

Answer 3

you can only do this with a static class. if you do not declare it static, you cannot access its members without instantiating.
