To import libraries in Visual Basic .NET, the Imports statement is used at the top of the code file. This statement specifies the namespace of the library that is being imported. Once the library is imported, its classes, methods and properties can be accessed without fully qualifying them.
Here are a few examples of how to import libraries in Visual Basic .NET:
Example 1 - Importing the System namespace:
``vb.net
Imports System
Public Class ExampleClass
Public Sub DoSomething()
' Use classes and methods from the System namespace without fully qualifying them
Dim now As Date = Date.Now
Console.WriteLine("The current date and time is: {0}", now.ToString())
End Sub
End Class
Example 2 - Importing a specific class from a namespace:
Imports System.IO.File
Public Class ExampleClass
Public Sub DoSomething()
' Use methods from the File class without fully qualifying them
Dim contents As String = ReadAllText("C:\example\file.txt")
Console.WriteLine("The file content is: {0}", contents)
End Sub
End Class
Example 3 - Importing a custom namespace:
Imports MyProject.MyNamespace
Public Class ExampleClass
Public Sub DoSomething()
' Use classes and properties from the MyNamespace namespace without fully qualifying them
Dim myObject As New MyClass()
myObject.MyProperty = "Hello World!"
End Sub
End Class
