thanks for ur reply...i tried what u said...even after it is not working...i know that file.copy method...but i want to deal with the matrix row by row...Is there any other way to deal with these datas...Already i posted one message related to this... http://www.codeproject.com/script/Forums/View.aspx?fid=1649&select=2973846&fr=151&df=90&mpp=25&noise=3&sort=Position&view=Quick#xx2973846xx[^] In that program ,i couldn't get the correct output..May be,i am thinking that Readline method is not the correct approach..Is there any other way to solve this problem

{
try
{
string path = "c:\\Vicky\\DATAS\\matrix.txt";
string path2 = "c:\\Vicky\\DATAS\\copy.txt";

            FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
            StreamReader sr = new StreamReader(fs);

            FileStream fs1 = new FileStream(path2, FileMode.Create, FileAccess.Write);
            StreamWriter sw = new StreamWriter(fs1);

            string line;
            while ((line = sr.ReadLine()) != null)
            {

                sw.WriteLine(line);

            }

            fs.Close();

thanks for ur reply....i don't know how file.copy() method is going to help in this program.here i am not copying the file to another path...i am just reading the the same row of every text file and copy it into new file..and u told me that this program will write 279 same files...but i am getting 279 different text files with different memory sizes....

i am new to c#.net...i am having 90 text files having image intensity values...i am reading n th row of every text file and write it into newly created text file....i have done this in matlab .i am getting correct output...but in this program i have done something wrong...because of that the no.of columns are not same in each row...i couldn't get the output image....here is the program

private void button1_Click(object sender, EventArgs e)
{

       try
        {
            
            string path1="c:\\\\Vicky\\\\DATAS\\\\OutputFiles";
            string path2 = "\\\\";
            string path4 = ".txt";
            DirectoryInfo dir1 = new DirectoryInfo(path1);
            dir1.Create();
                                         
            DirectoryInfo Dir = new DirectoryInfo(@"C:\\Vicky\\DATAS\\textfiles");
            FileInfo\[\] FileList = Dir.GetFiles("c\*.txt",SearchOption.AllDirectories);
            for(int t=1;t<280;t++)
            {
               string path3=Convert.ToString(t);
               string path=path1+path2+path3+path4;
               
               FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write);
               StreamWriter sw = new StreamWriter(fs);
               

            foreach (FileInfo FI in FileList)
            {
                FileStream fs1 = FI.OpenRead();
                StreamReader sr = new StreamReader(fs1);
                int i = 1;

                while (sr.ReadLine() != null)
                {
                    string d="";                      
                   
                        if (t == i)
                        {
                                

                                d = sr.ReadLine();
                                sw.WriteLine(d);
                                break;
                            
                        }
                      i++;

thanks man....we got it.....can u explain me wat problem we did it ....explain it briefly.

i am reading datas in text file and write into another text file..but getting exception ... FileStream fs=new FileStream("C:\\Vicky\\DATAS\\1.txt",FileMode.OpenOrCreate,FileAccess.Write); StreamWriter sw = new StreamWriter(fs); FileStream fs1 = new FileStream("c:\\one.txt", FileMode.Open, FileAccess.Read); StreamReader sr = new StreamReader(fs1); string[] s = new string[500]; for(int i = 0; i <= 500; i++) { s[i] = sr.ReadLine(); } for (int j = 0; j <= 500; j++) { sw.WriteLine(s[j]); } sw.Close(); sr.Close(); fs.Close(); fs1.Close(); error is: Index was outside the bounds of the array.in s[i]=sr.readline().....

thanks for ur reply....we r working on computed tomography project.....my part is 3d visualization.... i am having set of 2d images..somewhere i got books related to 3d visualization.....there they mentioned volume rendering is the technique used for 3d visualization ....thuts why i am asking here bout that....

i am having set of 2d images .....how to stack this 2d images to view 3d image......using volume rendering method ...how to implement in c# ..

i am doing project in computed tomography.....i have 2d images of full hand....i have to stack the 2d images to visualize the full hand

i am having set of 2d images....and i want to stack those images to visualize 3d image..i didn't get any idea.....i was searching in google,but i couldn't get exact details.....if anyone help me by giving any article or idea related to this......

I am a student of final year MCA doing a project on intelligent tutoring systems ,i dont know which algorithm to use that will suit best to my project.... help me!
