vb.net - display names from text

hello,
I have a text file with first names each one line by line..
I would like to know how can i display the first 10 records and delete them.

Dim x As Integer
For x = 1 To 10
Call Get_Names(x)
Next x

right now I have two functions one that read the first line and one that deletes the first one..
but doing this it has to open the file 10 times to read an another 10 times for deletes..

For a = 1 To 10
call Get_Names(x)

Next

2. another option

Do While x<11
call Get_Names(x)
Loop

why not read all the lines, perform our action and then delete the file completely:-

var lines = File.ReadAllLines("FilePath");

            var loopCounter = lines.Count()/10 + (lines.Count()%10 > 0 ? 1 : 0);

            for(int i=0;i<loopCounter;i++)
            {
                lines.Take(10).ToList().ForEach(Console.WriteLine);
            }

            File.Delete("FilePath");

If you do not want to read all the lines, easily achieved by amending this line to just read 10 lines.

TheFileLines.AddRange(System.IO.File.ReadAllLines(FileAddress))
