Solution 2

Run the below code.

C#

private static long CountLinesTextbox()
{
    string strText = TextBox1.Text;
    long count = 1;
    int start = 0;
    while ((start = strText.IndexOf('\n', start)) != -1)
    {
        count++;
        start++;
    }
    return count;
}

this might also help you to read all the lines in a textfile

VB

Dim oRead As System.IO.StreamReader
Dim FirstLine(1499) As String
oRead = IO.File.OpenText(Application.StartupPath & "\test.txt")
        Dim lineNo As Integer = 0
        While Not oRead.EndOfStream
            FirstLine(lineNo) = oRead.ReadLine
            lineNo += 1
        End While
