The similarities and differences between class and struct in. NET are described in detail!Class: put in? Put struct in? The struct value is passed. Classes have many similarities with structures: structures can implement interfaces and have the same member types as classes. However, the structure is different from the class in several important aspects: the structure is a value type rather than a reference type, and the structure does not support inheritance. The schema values are stored on the

Document directory Introducing the application domain AppDomains and you Shadow Copies and restarts Master of your domain In traditional development, we all know that an application corresponds to a process and specifies virtual memory for the process. The operating system maps the actual physical memory, it effectively maintains the security between processes. On the other hand, every process consumes a certain amount of system resources, reduces performance, and makes communication betwe

of private information disclosed on different occasions varies. Friends and family may know more about your privacy, followed by colleagues, and others may know less about it. Object-Oriented systems also consider these actual situations. Therefore, languages such as C ++ have keywords such as public, private, protected, and friend to adapt to different situations. Why: encapsulation can isolate changes. Based on past experience, we know that interna

repeatedly mentioned the following sentence in the course: Isolate changes . I think this sentence is the focus of the model and the goal of restructuring. If you think carefully and have rich project experience, you should be able to deeply understand the meaning of this sentence. This is the essence of the current model. How to isolate changes can be guided by the five principles. Under the guidance of t

Once the Squid configuration has been changed, the Squid service needs to be restarted. It may take several minutes to restart the service, depending on the number of active connections. During this period, LAN users cannot access the Internet. To avoid service interruption, we can use the following command instead of "service squid restart ". #squid-kreconfigure This command allows Squid to run with updated parameters without restarting itself. Filter LAN hosts by IP Address In this dem

Open-closed Principle It means that software entities (classes, modules, functions, and so on) can be expanded, but cannot be modified.This principle actually has two features:Open for expansion(Open for extension) ", the other is to say"Changes are closed.(Closed for modification )"What kind of design can we face the changes in requirements, but it can be relatively stable, so that the system can continue to launch new versions after the first version?No matter how close the module is, there wi

The general use of direct selection tool is to operate the point, there will not be too much need to put the other path of the point is also selected (unless you want to connect two paths, but there is a more practical solution, does not have to be set this way) . Similarly, the AI in the Lasso tool can also be selected, also can choose objects, so use the time is very careful not to choose other paths, but to be so careful, basi

Service restart a service: Systemctl restart Foo. Service Displays the status of a service (whether running or not): systemctl status Foo. Service Enable a service at startup: systemctl enable Foo. Service Disable a service at startup: systemctl disable Foo. Service Check if the service is started: systemctl is-enabled ipt

layer of the O S I model. The 2nd chapter has said that the network layer directs the data transmission from one network segment to another, and can also guide data transmission from one kind of networks to another. In the past, routers were slower than switches and bridges because of excessive attention to third-tier or higher-level data, such as protocols or logical addresses. Therefore, unlike bridges and second-tier switches, routers are protocol-dependent. Before they can use a protocol to
