streamreader

I've got a text file that contains several 'records' inside of it. Each record contains a name and a collection of numbers as data. I'm trying to build a class that will read through the file, present only the names of all the records, and then allow the user to select which record data he/she wants. The first time I go through the file, I only read header names, but I can keep track of the 'position' in the file where the header is. I need random access to the text file to seek to the beginning of each record after a user asks for it. I have to do it this way because the file is too large to

I am trying to retrieve an uploaded file from my webserver. As the client sends its files through a webform (random files), I need to parse the request to get the file out and to process it further on. Basically, the code goes as: HttpListenerContext context = listener.GetContext(); HttpListenerRequest request = context.Request; StreamReader r = new StreamReader(request.InputStream, System.Text.Encoding.Default); // this is the retrieved file from streamreader string file = null; while ((line = r.ReadLine()) != null){ // i read the stream till i retrieve the filename // get the file data out

Example: variable = new StreamReader( file ).ReadToEnd(); Is that acceptable? No, this will not close the StreamReader. You need to close it. Using does this for you (and disposes it so it's GC'd sooner): using (StreamReader r = new StreamReader("file.txt")) { allFileText = r.ReadToEnd(); } Or alternatively in .Net 2 you can use the new File. static members, then you don't need to close anything: variable = File.ReadAllText("file.txt"); You should always dispose of your resources. // the using statement automatically disposes the streamreader because // it implements the IDisposable interface

Hello I am working on something, and I need to be able to be able to add text into a .txt file. Although I have this completed I have a small problem. I need to write the string in the middle of the file more or less. Example: Hello my name is Brandon, I hope someone can help, //I want the string under this line. Thank you. Hopefully someone can help with a solution. Edit Alright thanks guys, I'll try to figure it out, probably going to just rewrite the whole file. Ok well the program I am making is related to the hosts file, and not everyone has the same hosts file, so I was wondering if
