. Let's take a look at the asynchronous programming demonstration demonstrated by the Anders demo. Your future Windows programming will be indispensable. 2. Windows Runtime IntegrationAnders shows that the new Windows Runtime has been deeply integrated. NET and C #, for example, using C # as the "Compute engine" and then outputting the HTML/JavaScript Metro App (

For this reason, some websites adopt methods such as sending passwords by email and URLs of special resources, or require users to reply to emails to ensure the validity of the email address. However, these methods are not always effective. For example, you may not collect user emails from your website, but get them through a third party.　　For these reasons, the most fundamental way to verify the legitimacy of the emai

In the C/S stage, we learned software engineering, UML, and VB. net, the design model, three-tier architecture, and a simple understanding of the C # language basics. With the accumulation of these theories, we began to use the data room charging system for practice, only by practicing this knowledge can you become a real person, because you can understand it deeply only when you are a real person. The ind

to the method for the subclass to redefine the virtual function of the parent class. Note: When the methods defined in the parent class are modified with the keyword overridable, The subclass uses the keyword overrides to define the methods with the same name in the parent class, so that the methods defined in the subclass will overwrite the methods with the same name in the parent class. 2. Overload: multiple functions with the same name are allowed, and the parameter tables of these functions

code in the Catch Block does not run. Instead, it skips the Catch Block and directly runs the cleanup work in the Finally block. If an exception Catch Block is encountered, the processing is required. Why is the Finally block cleaned up? Simply put, a program exception will cause the program to fail to complete the work normally, and jump out of the program where the error occurs, and directly execute the code in the Catch statement block, this prevents the object Resources built during the pro
