Streamreader .txt file

Question

Sir/Ma'am I have a .txt file int the following format: [test1] blue red green [test2] one two three [test3] white black grey I'm trying to read the everything below [test2] and above [test3] into a combobox. So I'm trying to populate comboBox1 with one two and three. I thought this might work but I was wrong: { comboBox1.Items.Clear(); using ( StreamReader sr = new StreamReader ( @c:	est.cfg )) { String line1; do { line1 = sr.ReadLine(); if (line1.StartsWith( [test2 )) { line1 = line1.Split( ']' )[1].Trim(); String [] strgArray; strgArray = line1.Split( '
' ); foreach ( String strg in strgArray) { comboBox1.Items.Add(strg.Trim()); } break ; } } while ((line1 != null )); Console .Read(); } } } THANK YOU!!!

Hi Which set needs to populate with combo? Exactly [Test2] items or Any set of items coming second those items?

Sirs You guys nailed it! You came up with exactly what I asked for. However I did a poor job of trying to articulate what I was try to accomplish. I'm trying to make the .cfg file dynamic so the the order in which the [test1] [test2] and [test3] won't matter. From what I asked test2 would have to be between [test1] and [test3] for combox2 to be populated with the data. However what happens if the user moves [test2] up one position. Thus [test1] would be populated in the combobox. Again I appreciate the help!

Try this. It seems like ur logic never went through the idea that ReadLine() will move through line by line only. using (StreamReader str = new StreamReader ( @c:	est.cfg )) { String line1; while (!str.EndOfStream) { line1 = str.ReadLine(); if (line1.StartsWith([test2)) { line1 = str.ReadLine(); while (!line1.StartsWith([test3)) { //ADD ITEMS HERE////////////// line1 = str.ReadLine(); } } } }

hi friend i have worked on your code.. it is reading form the file and binding to combobox is working well: using (StreamReader sr = new StreamReader(@c:	est.cfg)) { String line1; while (sr.ReadLine() != null) { line1=sr.ReadLine().Trim(); if (line1 == [test2]) { break; //You can populate here another combobox or dropdownlist list what ever be your control } else { if (line1.Contains([)) continue; else { ComboBox1.Items.Add(line1.Trim()); } } } } But there is a problem i found that your string [test1] is not readable by StreamReader. it just getting skipped while reading from file and so the condition if (line1 == [test2]) never gets executed. Hope it helps. Please mark as answer if you get some help.
