Just use a counter to count the lines of text as you read them.

If i understand you well, you want to return the number of line where searched text has been found...

So:

C#

string[] lines = {"asdasd", "Testa", "Geter", "Better"};
string tofind = "te";

var result = lines.Select((line, NoOfLine) => new {line, NoOfLine})
	.Where(l => l.line.Contains(tofind))
	.Select(l => l.NoOfLine)
	.ToList();
//returns: {2, 3}
