Question

What is the simplest way of importing items from a text file into a ComboBox control? The text file contains multiple lines. I need to add each line from the text file as an item in the combo box.

Answer 1

If the format of the text file is one combo box item per line, and you want to load them into a WinForm ComboBox control, then this would be the simplest way to do it:

ComboBox1.Items.AddRange(File.ReadAllLines(filePath))

You’ll need to add Imports System.IO to the top of the code file. Either that or specify the full name of the File class:

ComboBox1.Items.AddRange(System.IO.File.ReadAllLines(filePath))
