This article introduces the relevant knowledge of "what is the role of C# and ASP.NET". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

.net platform

According to Microsoft's definition: .net is a "revolutionary new platform, built on open Internet protocols and standards, with tools and services that meld computing and communications in new ways", that is, .NET = new platform + standard protocol + unified development tool.

.net represents a collection, an environment, and a programmable structure that can be used as a platform to support the next generation of Internet. The ultimate goal is to enable users to access the required information, files and programs anywhere, at any time, and on any device.

The .NET platform mainly consists of four parts: low-level operating system, .net enterprise server, .net framework and integrated development tool Visual Studio.Net.

1. Low-level operating system

With the help of its leading position in desktop operating systems, Microsoft has brought the windows series of operating systems to the .net platform.

Currently, Windows2000, WindowsXP and Windows2003 support the .net platform.

2.Net Enterprise Server

The .net platform also provides a series of servers for enterprises to use.

Exchange 2000 Server: Exchange is not a simple Email Server, it is an out-and-out information platform.

SQL Server 2000: SQL Server provides complete data processing capabilities. Includes data mining, direct Internet support for XML. SQL Server 2000 Windows CE Edition is currently available in Windows CE.

BizTalk Server 2000 is used to exchange business information between enterprises. it uses XML as the data format for document transmission within and between enterprises, which can shield the differences of different platforms and operating systems, and make the integration of business systems possible.

Commerce Server 2000 is used to quickly create online e-commerce.

Mobile Information Server provides a reliable and scalable platform for mobile information resolution servers.

3. Net framework

The .net framework mainly includes the common language runtime (Common Language Runtime CLR) and the .net framework class library (FCL).

4. Integrated development tool Visual Studio.Net

Microsoft integrates all her development tools into Visual Studio.Net, which can be developed in C # language, C++ language, Basc language and J# language in Visual Studio.Net. Can develop desktop applications, Web applications, smart device applications, and so on.

What can NET do? It provides a new development platform for the development of Internet network and distributed applications. Simplify the development and deployment of applications, provide a standard platform for building Web Service, and improve the interaction and integration between systems and applications. Make the application accessible to any device.

C#

On the Microsoft .net platform, C # is the main language for development. C # is a new programming language developed by Microsoft. It is derived from C and C++, so it has the function of C++. Because it is a product of Microsoft, it is as simple as VB. For web development, C # is similar to Java development language, but also has some advantages of Delphi. So Microsoft claims that C # is the language for developing .NET Framework applications.

The. Net platform uses C # as its inherent language and reviews many of the technical rules of Java. There is also a virtual machine in C # called the Common language Runtime Environment (CLR), whose objects have the same hierarchy. But C# is designed to use all Win32 API or more. Because the architecture of C # is similar to that of Windows, C # is easily known to developers.

ASP.NET

ASP.NET is a programming framework built on the common language runtime that can be used to generate powerful Web applications on the server. Compared to previous Web development models, ASP.NET provides several important advantages:

Enhanced performance. ASP.NET is compiled common language runtime code that runs on the server. Unlike the explained predecessors, ASP.NET can take advantage of early binding, just-in-time compilation, native optimization, and out-of-box caching services. This is equivalent to a significant performance improvement before a line of code is written.

* * tool support: the ASP.NET framework complements a large number of toolkits and designers in the Visual Studio integrated development environment. WYSIWYG editing, drag-and-drop server controls, and automatic deployment are just a few of the features provided by this powerful tool.

Power and flexibility: because ASP.NET is based on the common language runtime, Web application developers can take advantage of the power and flexibility of the entire platform. .net Framework class libraries, message processing, and data access solutions are all seamlessly accessible from Web. ASP.NET is also language-independent, so you can choose the language that works best for your application, or split applications across multiple languages. In addition, the interactivity of the common language runtime ensures that existing investments in COM-based development are retained when migrating to ASP.NET.

Simplicity: ASP.NET makes it easy to perform common tasks, from simple form submission and client-side authentication to deployment and site configuration. For example, the ASP.NET page framework allows you to clearly separate application logic from presentation code in the user interface and handle events in a simple form handling model like Visual Basic. In addition, the common language runtime takes advantage of managed code services such as automatic reference counting and garbage collection to simplify development.

Manageability: ASP.NET uses a text-based hierarchical configuration system that simplifies the application of settings to server environments and Web applications. Because the configuration information is stored in plain text, the new settings can be applied without the help of local administrative tools. This "zero local management" philosophy also extends to the deployment of ASP.NET framework applications. Simply copy the necessary files to the server to deploy the ASP.NET framework application to the server. There is no need to restart the server, even when deploying or replacing running compiled code.

Scalability and availability. ASP.NET is designed with scalability in mind, adding features specifically designed to improve performance in aggregation and multiprocessor environments. In addition, processes are closely monitored and managed by the ASP.NET runtime so that when processes behave abnormally (leaks, deadlocks), new processes can be created in place to help keep the application always available for processing requests.

Customization and extensibility: ASP.NET comes with a well-designed structure that allows developers to "insert" code at the appropriate level. In fact, you can extend or replace any subcomponent of the ASP.NET runtime with custom components that you write yourself. It becomes easier to implement custom authentication or stateful services.

Security: applications can be secured with built-in Windows authentication and per-application-based configuration.
