本篇文章主要介绍了"VB.net Module",主要涉及到VB.net Module方面的内容,对于VB.net Module感兴趣的同学可以参考一下。

In this tutorial, we cover how to create a module, store information inside a module and then access that information in your application. A module can be used to store functions, subs or even variables to sort out your code so that you can access things more easily. If you have a sophisticated application where you have to store a lot of functions, subs or variables then it would be useful to sort them into different categories using modules. A module is differen t to a class because all of the members of a module are shared and a module does not have a consutrctor, meaning you can not create an instance of a module. Module Code Module functions Public bla As Integer = 10 Public bla2 As Integer = 20 Public Function addnumbers(ByVal number1 As Integer, ByVal number2 As Integer) Return number1 + number2 End Function End Module Code Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click TextBox3.Text = addnumbers(bla, bla2) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click MessageBox.Show(addnumbers(TextBox1.Text, TextBox2.Text)) MessageBox.Show(functions.addnumbers(TextBox1.Text, TextBox2.Text)) End Sub End Class
