The full name of NET language is "ASP.NET". It is a new programming framework theory or a programming standard introduced by Microsoft. It can be used for project development and application through the Visual Studio development tool produced by Microsoft. The development of website classes is generally written in "C#" language, and the application class is generally written in VB.
The full name of NET language should be ASP.NET. It is a new programming framework theory or a programming standard launched by Microsoft. It can be passed through Microsoft The produced Visual Studio development tools are used for project development. The development of website classes is generally written in C# language, and the application class is generally written in VB.
Programs written in this language can run on all operating systems with net frame installed (in theory, I have not tested it in practice), and have cross-platform characteristics.
It is said that the purpose of Microsoft launching net is to compete with java, because java can run on any operating system through the java virtual machine (cross-platform).
1..net framework is divided into two parts:
CLR: Common Language Runtime (Common Language Runtime), which provides internal management, code security detection and other functions.
FLC: .NET Framework Class Library, which provides a large number of application class libraries. There are many thread resources available in the class library (such as classes, methods, properties) to improve development efficiency. .
2. CLR structure:
CLS: Common Language Specification, which converts various languages into unified syntax specifications.
CTS: Common type system, converts data types in various languages into unified types
JIT: Just-in-time compiler (just-in-time compiler) is used to compile the converted language into Binary language is handed over to the CPU for execution.
3 .NET operation mechanism process
Various languages (corresponding source programs for c#, F#, j#, etc.)——>Compiled for the first time by CLS and CTS——> Unified specification language (intermediate language) MSIL (.EXE, .DLL)——>JIT second compilation——>Binary language——>Running in CPU
Java operating mechanism:
java——>Compilation——>Bytecode file (.CLASS)——>jvm interpretation (jvm virtual machine)——>Binary language——>Run in CPU
