add a static method to a subclass in csharp

To add a static method to a subclass in C#, you can simply declare the method with the static keyword within the subclass.

Here's an example:

main.cs
public class MyBaseClass 
{
    // ... base class implementation
}

public class MySubClass : MyBaseClass 
{
    // Static method declared within MySubClass
    public static void MyStaticMethod() 
    {
        // Implementation goes here
    }
}

In the example above, MySubClass inherits from MyBaseClass. The static method MyStaticMethod() is declared within MySubClass and can be accessed without creating an instance of the class.

You can call the static method using the class name like this:

main.cs
MySubClass.MyStaticMethod();
