Question

I am currently trying to make a ListBox its values from a text file – values.txt

The values.txt file contains a different value on each line e.g.

Value1
Value 2
Value3
Value 4

How could I use the values in this text file to be used within the ListBox?

Answer 1

Well, first read the text using either StreamReader or File.ReadAllLines.
Then, add the data to your ListBox.
Example:

listBox1.Items.AddRange(File.ReadAllLines(@"C:\file.txt"));

It should work.
