Question

Hello friends I face this question in one Interview in statics(Myclass). I have two clases one is M1 and M2 .

How can I call m2 in m1 and m1 in m2? and also How to create an Instance of an static?

static void Main(string[] args)
        {
          //in this Portion How can I call all member if MyClass
        }


     public static class Myclass
                {
                    public static class  M1
                    {
                     //Here How can I call m2
                    }
                    public class m2
                    {
                    //Here How can I call m1
                    }
                }

For static class M1, you need to call using class name. For non static class M2, you need to create instance. you can call methods/properties, and not classes.

public static class Myclass
    {
       public static void Main(String[] args)
       {
          // call something on  m2
          var m2 = new Myclass.m2();
          m2.A2(); // call m2.A2 method

          // call something on m1
          Myclass.m1.A1();
        }
        public static class M1
        {
            //Here How can I call m2
            public static void A1()
            {
                var m2 = new Myclass.m2(); // create m2instance
                m2.A2(); // call m2
            }
        }
        public class m2
        {
            //Here How can I call m1
            public void A2()
            {
                Myclass.M1.A1(); // called M1.A1
            }

        }
    }

You can not call a class, and as it is static you can not Generate new class of that type but you can call methods and functions of it easily like this:

public static class Myclass
            {
                public static class  M1
                {
                 public static class Method2(){
                  }
                  new m2().AMethod();
                }
                public class m2
                {
                //Here How can I call m1
                 public static void AMethod(){  
                     //method 
                }
             }
          }

And for main:

static void Main(string[] args)
        {
          new MyClass.m2().AMethod();
          MyClass.M1.Method2();
        }
