Editor to share with you the example analysis of VB.NET namespace, 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 namespace

When writing .NET software, we use classes and other types. To make your application more organized, you can combine classes into namespaces, as is the case with Microsoft's .NET Framework class library. If you open the. NET Framework Class Library in the .NET Framework SDK document, you will see that there are more than 80 namespaces, often and even important namespaces, including System, System.IO, System.Drawing, System.Windows.Forms, and so on. For example, in the PrintSalary method of the Employee class, we use the Console class in the System namespace.

If you want to use a namespace in your program, you can import it first so that you don't have to repeat the name of the VB.NET namespace every time you use its members later.

Import VB.NET namespaces

Class Employee Dim salary As Decimal = 40000 Dim yearlyBonus As Decimal = 4000 Public Sub PrintSalary () 'print the salary to the Console System.Console.Write (salary) End Sub Public Shared Sub Main () Dim employee As Employee employee = New Employee () employee.PrintSalary () End Sub End Class

Well, we can now use the Console class in the PrintSalary method without referring to the namespace, because we have imported the VB.NET namespace.

We can also have classes with the same name in different namespaces. To use a class correctly, it is common to use the name of the namespace in front of the class. For example, you can use the Console class in the System namespace as System.Console.

The above is all the content of the article "sample Analysis of VB.NET Namespace". 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!
