in these unv file how to read block i.e from -1 to -1
in unv file they are storing data between -1 to -1

i wrote a code in c# where m calculating how many -1 are there in file.
but these code is not working.
plz help me...
thanks in advance

First, explain what an UNV file is. Unless it's a proprietary file, you should be able to find the format somewhere that will tell you how the data is layed out.

Use that to figure out how many bytes you need to read to retrieve the data you're interested in (or at least how to get to it first).

Reading the file is straightforward as you just need a simple filestream and a streamreader.

yes i know that reading the file is very easy that i already did.
you plz see the file dat i send u

With the message "My code is not working, please help me", we can do nothing to help you. Please show us your code and point out WHAT EXACTLY is not working

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;


namespace Project
{
    class Program
    {
        static void Main(string[] args)
        {
            string filename = "1.unv";
            string line = null;
            int count = 0,i=0;

           List<int> list=new List<int>();
            StreamReader reader = new StreamReader(filename);
            while ((line = reader.ReadLine()) != null)
            {
                if (line.Contains("    -1"))
                {
                    count++;
                    list.Add(count);
                }


                }
                reader.Close();
                Console.WriteLine("count:"+count);
               Console.WriteLine(list.Capacity);
                Console.WriteLine("count list:"+list.Count);
           // Console.WriteLine(list.);
                //list.Clear();

                Console.ReadLine();



            }
        }
    }

in my code m calculating how many -1 is there

Well, you've asked if a line contains 4 spaces a - sign and a 1 and so it will look for exactly that. If the line contained only 3 spaces a minus sign and a 1 then it wouldn't match.

I still don't see what file you're referring to. You have neither attached, not given a link location that contains this UNV file.

Is it a text file? If not, your code won't work anyway.

Also, what is the list for? You have a count variable, why are you adding it to a list everytime you find one?

if u see the file u can find they are storing value in the block i.e from -1 to -1

Could you please upload the file "1.unv"?

     -1

this is the 1.unv file

The data looks tabbed. Try checking for "\t-1" instead.

Also there is a lot of -1 throughout the entire file. Are you interested in any in particular?

yeah there are lots of -1 bt i want to read the data block by block(i.e -1 to -1)

Is there any reason why you are putting the increment of count into list? Lines 24 25 of your code.

no it is not required

You say you want to read a block of -1 to -1, but there's a lot of -1's in that file. It seems you need a new way of thinking through this one because simply looking for -1 and reading everything to the next -1 is not going to work.

Personally I would parse the lot into a couple of structures based upon the knpowledge you have regarding the file and data it contains.

    %                   basic information from the file. UffDataSets will be returnedfunction [UffDataSets, Info, errmsg] = readuff(varargin)
    %READUFF Reads UFF (Universal File Format) files of types:

    %                   empty in this case.
    %
    %   [UffDataSets, Info, errmsg] = readuff(fileName) Extract the basic
    %                   information from the file as well as the whole file
    %                   contents - see the description for the UffDataSets
    %                   below.
    %
    %   [UffDataSets, Info, errmsg] = readuff(fileName, recs) Extract only the
    %                   records and their information requested by the recs
    %                   array - the array of indices, e.g., recs=[1 3 10]. If
    %                   empty, all the records are considered.
    %
    %   [UffDataSets, Info, errmsg] = readuff(..., recs, dsTypes) Extract only the
    %                   records that meet the criterria of the dsTypes where
    %                   dsTypes is an array of data-set types that are to be
    %                   read - actually, this is another filter in addition to
    %                   the recs one; e.g. dsTypes = [58 55]

    % [v.1.0.1-1.0.5] 12.03.2008-08.11.2008
    % - NEW: some restrictions relaxed when reading the data-set 58
    % - NEW: some additional checking for badly formatted data-set id line
    % - NEW: some additional warning/error messages displayed for the 58b set
    % - FIX: uint8=>char instead of char=>char in fread fixes a problem on
    %        some Linux systems
    % - FIX: minor bug removed (related to the extracted abscissa values for
    %        the 58, complex case of data)
    % [v.1.0.0] 10.03.2008
    % - NEW: datasets 2411 and 2412 added
    % [v.0.9.9b1-5] 08.01.2008
    % - NEW: additional checking when reading 58b data
    % - NEW: additional filter added - dsTypes
    % - FIX: minor bug removed concerning the finding of the "    -1" tags
    % - FIX: previously, when reading data-set 58b, some data-sets were
    %        skipped; this bug is now removed
    % - NEW: new functionality to read only a portion of file and to extract
    %        the information only
    % [v.0.9.7-v.0.9.8b7] 28.02.2006
    % - FIX: a bug reading even abscissa data from the 58 set removed
    % - NEW: uneven abscissa data-reading is now supported
    % - FIX: removing leading and trailing spaces from the strings read
    % - NEW: hybrid binary-58 format (58b) is now supported
    % - NEW: binary field was added to UffDataSets structures
    % [v.0.9.7] 24.05.2005
    % - NEW: dsType field was added to UffDataSets structures
    % [v.0.9.6b4] 11.05.2005
    % - FIX: Matlab version down to 5.3 is now supported
    % - FIX: Some minor bugs removed
    % - NEW: Speed improvement; reading is much faster now

this is the matlab code which is reading unv file.with the help of these code i have to write the code for c#...nd m nt aware of matlab code.this matlab code tells how they are extracting data from unv file

Perhaps this can do it(referring to line22 of your code):
if (line.Equals("\t-1"))
It seems your special separator is always on one line, so I guess it can only contain "\t-1" and so there would be no interference with other -1's used.

if(line.equals("\t-1")) is not counting how many -1 is there

if (line.Equals("\t-1")) is not showing how many -1 is there

Did you ever try to debug it and set some breakpoints?
