Editor to share with you what is the use of VB.NET, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

VB.NET is a new version of VB released after VB 6. 0. If you are a master of VB.NET, you can skip this section.

Find out what you can do to learn VB.NET:

(1) understand why VB.NET is chosen as the language of ASP.NET programming.

(2) knowledge of variables, constants and expressions

(3) can use conditional and loop statements

(4) understand how to use procedures and functions.

Selection of programming language for preliminary knowledge of VB.NET

Because ASP.NET is only a programming environment, in order to program in this environment, we must choose a language. In early ASP, the default language used was the VBScript scripting language. Since the .NET Framework already supports non-scripting high-level languages such as VB, it is no longer necessary to use VBScript, but programs originally written in VBScript can still be executed in ASP.NET because the .NET environment still supports VBScript syntax.

Languages supported by. Net for preliminary knowledge of VB.NET

Net provides users with three programming languages: VB.NET, C # and Jscript. This section describes each of these three languages.

VB.NET is the version of VB***, which can be said to be a great leap forward in terms of function and performance. First of all, the early version of VB does not fully support object-oriented programming, because it does not support object inheritance and overloading, so there are a lot of problems. In addition, early versions of VB could not create multithreaded applications, so they could not make full use of the machine's resources and improve the execution efficiency of the application. But now, because VB.NET uses CLR, these problems have been well solved.

As for C language, it can be thought of as a new language founded on the basis of C and C++. It inherits the excellent features of C++, removes the type definitions, templates and other functions that are useless in the .NET environment, and makes C # easier to use and much more efficient than C++.

Like VB.NET, JScript.NET is developed from JScript. JScript.NET is rewritten entirely in C #, it supports types and inheritance, and is fully compiled and executed. In order to ensure that the original JScript program can still execute correctly, it still supports existing JScript code.

Why did you choose VB.NET for the preliminary knowledge of VB.NET

The reason why this book chooses VB.NET as the programming language is: first, VB.NET is the default programming language of ASP.NET; second, VB.NET is very easy for beginners to learn, and you can use it to accomplish all the functions that C# and JScript.NET can accomplish.

The above is all the content of this article "what's the use of VB.NET?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
