Please, next time you want to answer someone who wrote a solution, use the "Have a question or comment" button below the message of the person you want to answer to. He/she will get a notification and it keeps the thread cleaner. Adding answers just to comment or give feedback to other user makes it a bit chaotical

Solution 1

You don't need a class at all -it's only two lines of code!

C#

string[] lines = File.ReadAllLines(fileName);
Array.Sort(lines);

Solution 4

The text can be read and sorted as given in solution 1 by OriginalGriff. Now, to use OpenFileDialog and to display in ListBox, use the following code in the Click event of the Button

C#

OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.ShowDialog();
string[] dataFromFile = System.IO.File.ReadAllLines(openFileDialog.FileName);
Array.Sort(dataFromFile);
listBox1.DataSource= dataFromFile;

Thankyou very much friends, it works.....
My professor told me to look for a standard class in c#, tha will be the same for all textfile.... but I think like OriginalGriff. in this case we dont need class...

Thank you !
