How to use Modules and Class method in the VB.Net?
First , we must know Modules and Class in the VB.Net.
Modules:
Modules are VB counterparts to C# static classes.
you don't want to allow inheritance and instantiation, you use a Module.
Class:
A class is a collection of objects of similar type. Once a class is defined, any number of objects can be created which belong to that class.
Methods
A Method is a procedure built into the class. They are a series of statements that are executed when called.
Sub Procedures
Sub procedures are methods which do not return a value. Each time when the Sub procedure is called the statements within it are executed until the matching End Sub is encountered.
Function is a method which returns a value. Functions are used to evaluate data, make calculations or to transform data. Declaring a Function is similar to declaring a Sub procedure. Functions are declared with the Function keyword.
Example call Module function and Class methods
Here , i give a program for get splitting a string using function in VB.net
In vb.Net Function will return a value.
Module Module1
Function splittingvalue(ByVal strigs As String, ByVal sr As Char) As String()
Dim st As String() = strigs.Split(New Char() {sr})
Return st
End Function
Public Class Class1
Public Shared Sub displaymessage()
MessageBox.Show("Good Luck")
End Sub
End Class
How to call Functions and Methods in the Application?
Class1.displaymessage() // Method...
Dim result As String() = Module1.splittingvalue("Lakshmi", "k") // Function
Dim conResult = result(0) + result(1)
MessageBox.Show(Convert.ToString(conResult))
