. The Controller receives the request from the client and selects the view to serve the request.. Selection of MVC and web forms Compared with web forms, MVC has a series of advantages: Separation of models, views, and controllers makes unit tests in various aspects of applications easier. More control over MVC applications in terms of details This avoids the transmission of a large amount of State data on the server and client, while web forms cause a lot of trouble on the

Abstract:Rocky Lhotka recommends and implements a structured architecture example, which can act as a medium between the auxiliary thread and UI thread, thus simplifying the process of writing multi-thread auxiliary code and UI to control it. This architecture includes downloadable code examples, which can be adjusted based on your application needs. With multithreading, applications can execute multiple tasks at the same time. With multithreading, one thread can run the user interface, and anot

The two basic components of the ADO. Net object model are generally: One is a dataset, which is disconnected from the data source and does not need to know the source of the maintained data; The other is the. NET data provider. the. NET data provider can connect to the data source and execute SQL commands for the data

application that needs to manipulate the dataset. However, as with all data cleansing programs, they never seem to have been completed. It seems always necessary to write code for the new checksum type and cleanup task. Of course, you can create new cleanup logic and recompile the entire application, but is it better if you can dynamically insert new data cleansing without recompiling the main application? Let's start by creating an example from scr

1. Out-of-class: Why can an object array be assigned the object type, but an int array cannot be assigned the int type?A: No matter what Array, It inherits from Array, while Array inherits from object.2. Thread: it is the basic unit for the operating system to allocate the processor time.3. An operating system that supports preemptive multi-task processing can create multiple threads in multiple processes for simultaneous execution.Implementation: div

What is the use of. net basic EventArgs? It suddenly finds that EventArgs is useless. It is similar to viewmodel. It only indicates that this class stores data and can run without inheriting EventArgs programs. There is only one benefit to using this function. No matter what EventArgs we define, this parent class can be used in the method. For example Public v
