说明：  编写一个控制台应用程序，完成下列功能，并写出运行程序后输出的结果。 1) 创建一个类A，在A中编写一个可以被重写的带int类型参数的方法MyMethod， 并在该方法中输出传递的整型值加10后的结果。 2) 再创建一个类B，使其继承自类A，然后重写A中的MyMethod方法，将A中接 收的整型值加50，并输出结果。 3) 在Main方法中分别创建类A和类B的对象，并分别调用MyMethod方法
(Write a console application, complete the following functions, and write the output after running the program results. 1) create a category A, in A in the preparation of a can be rewritten with int type parameters MyMethod, and in the methods of transmission of the output value of 10 after cosmetic surgery results. 2) re-creation of a category B, so that it inherited from the category A, and then rewrite A in MyMethod method to receive the integer A value of plus 50, and output results. 3), respectively, in the Main method to create category A and category B of the object, and call respectively MyMethod method)
