Question

I have data in the form of from TextBox1

00 00 00 4E FF 53 4D 42 25 00 00 00 00 18 01 28  ...N.SMB%......(
00 00 00 00 00 00 00 00 00 00 00 00 00 08 12 8B  ................
01 08 7E 31 11 00 00 05 00 00 00 00 00 00 00 02  ..~1............

and I tried to change it to be like this on the result TextBox2

...N.SMB%......(
................
..~1............

I’ve tried the function *. remove but only the first row are deleted but the second line and so on are not deleted. Can anybody help me?

i use this code

string test = rtText1.Text;
rtText2.Text = test.Remove(0, 48);

and then this result rtText2

...N.SMB%......(
00 00 00 00 00 00 00 00 00 00 00 00 00 08 12 8B  ................
01 08 7E 31 11 00 00 05 00 00 00 00 00 00 00 02  ..~1............

how can I make a command “test.Remove (0, 48);” can be done on each line? or is there another function?

It’s hard to say exactly what you need based on what you’ve posted, but a regex may work well here:

TextBox2.Text = System.Text.RegularExpressions.Regex.Replace(
                    TextBox1.Text, 
                    @"^.{49}", 
                    "", 
                    RegexOptions.Multiline );

This will simply replace the first 49 characters of each line with an empty string.
