Stream Reader Problem

Paul Unsworth

Hi Guys I have quite an urgent problem which is really getting on my nerves... I have a stream reader which goes through a file line by line, and extracts information. The problem I have though, is that for some reason, the very first character is getting left out... string chkLine = ChkReader.ReadLine() Does anybody know why this could be happening? :( Thanks

oooo, the Jedi's will feel this one....

Is the first character anything special? What encoding are you using? Is the first character even there - check with a hex editor? I use StreamReader quite a bit, and it's never given me a problem, and never left out any characters.

Try setting a break point in the below code snippet: foreach (char c in ChKReader.ReadLine()) {} See if it is picking it up using that.

Just tried your suggestion. It still misses it out... :(

Is the text file ANSI encoded?

The first character is a number. nothing special. It misses all of them though. It's not like it's just dropping a leading zero... It is very baffeling. Just does not make any sense. :(

You mean it misses the first character of every line? File:

0Hello
1There
2Goodbye

gives you three lines "hello", "There" and "Goodbye"? What is so different about your code from the standard and very boring:

        using (StreamReader sr = new StreamReader(@"C:\\XXTemp\\Lines.txt"))
            {
            string s;
            while ((s = sr.ReadLine()) != null)
                {
                MessageBox.Show(s);
                }
            }

Thats the assumption I'm making. Although I'm not sure how to check. The text file appears to be a straight forward text file for use with the likes of notepad.

My code is:

while (chkReader.Read())
{
string chkLine = chkReader.ReadLine();
}

I just created a new text file of my very own and pointed my app at it and got the following: Actual line in file: "Hello There" Line picked up in chkReader.ReadLine(): "ello There" :sigh:

Well its hard to say, I would try creating a whole new text file, and typing in a few of the problem lines. That way you will know if the problem is the text file or your code. The code you posted should work fine...

Hi, you could create your special stream reader that does exactly that, or there could be something very special about your file (not sure what). To make sure, use a hex editor/dumper to look at the first few lines of data. :)

There's your problem: the while(chkReader.Read()) reads and discards the first character of each line...
