C # provides a new type of loop: foreach, which is closely related to the set interface in the. NET Framework. In the program, we should use foreach for loop first. Let's take a look at the following code snippet: Code Code highlighting produced

Struct can all be replaced by class. Why should I use struct? The existence is reasonable. struct has many advantages in performance. Let's take a look at the main differences between them? The data types are different. struct is the value type,
