To solve this problem, you just need to apply these recursive relationships over and over again. (Note: To avoid unnecessary wrapping of lines of code and to ensure the readability of the code, the following code uses a very short variable name.)

1, the basic characteristics of the object Each object has its own unique identity. Objects communicate with each other through a message. The object is always in a certain state. Objects have several behaviors that fall into

Dependency property: A property that can own no value and can derive a value from a data source by using a binding (dependent on someone else).Let's take a small example: the value of the second text box is dependent on the first text box, which is
