var text = "1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234" + Environment.NewLine + "1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234";
const String padWith = "9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999";
const int lineNum = 10;
var lines = text.Split(new[] { Environment.NewLine }, StringSplitOptions.None).ToList();
while(lines.Count < lineNum) {

Here goes the code.

1) Find out the no of lines in your file

2) make count%10, if count%10==0 do not pad else 10-result=required length , Pad with required length.

Sample code assume you have 8 lines 

    int cnt = 8; 
    int result = cnt % 10;  // Will get 8
    int iresult1 = 10 - result;

Hope it helps
