This article mainly shows you "VB.NET how to generate code dynamically", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to dynamically generate code in VB.NET" this article.

The first is when programmers need to dynamically build a control and attach code to it. For example, you may want to create a list of links, but you don't know how many links need to be created or what kind of data will appear in the links. The second is when programmers need to define code to reflect special requirements. For example, you may want to execute code that reflects the user's system configuration.

Things like the above certainly don't happen every day. In fact, they only appear in extraordinary circumstances. However, as a programmer, you should still be aware that .NET provides a solution to dynamic situations. With the right skills, you can write applications that can handle dynamic situations flexibly.

VB.NET dynamically generated code using dynamic controls

Many programmers always encounter a time when they need to create controls dynamically. In the example we show, the programmer adds LinkLabels to FlowLayoutPanel. Maybe you can use this setting to record and save the values of commonly used URL, files, network addresses, or other resource locations. This example doesn't really save the link, but you can use the XML serialization feature to save it.

Each time the user clicks the Test button, the sample code dynamically creates a new LinkLabel control. The real demo code is not complicated. Example 1 shows everything you normally need to do to create such controls and put them into FlowLayoutPanel,lstLabel.

VB.NET dynamically generated code sample: add a new link to FlowLayoutPanel

Private Sub btnTest_Click () Handles btnTest.Click 'Create a link. Dim NewLink As LinkLabel = New LinkLabel () 'Add some properties to it. NewLink.Text = DateTime.Now. ToLongTimeString () 'Set the click event handler. AddHandler NewLink.Click, AddressOf NewLink_Click 'Place the button on the form. LstLinks.Controls.Add (NewLink) End Sub above is all the content of this article "how to generate Code dynamically in VB.NET". Thank you for reading!
