either a positive number or a negative number, for example, a negative step: 2. In: The usage of in is relatively free. You can understand the content after in as all elements of a list variable. This loop is equivalent to traversing each element. The element here can be a string or a value. Therefore, you can directly write the elements as I did, or directly put a list variable. For example: The running result is as follows: The specific use of in or in range depends on the specific needs

library. The code that uses the defined class is generally referred to as the customer code.In order to use the classes in Ch09classlib, a reference to Ch09ClassLib.dll is added to the console application. For this example, the reference is an output file to the class library, or it can be copied to the local location of CH09EX02 to continue developing the class library without affecting the console application. In order to replace the old version of the assembly with the new class library proj
