How to make output in columnar format

Question

13 Years Ago

My text file is delimited (2 fields (text & numeric)). I'm trying to get the output into columnar format and include a count of the # of records following the columnar format. My text file is separated by commas. So far I can only read the text file. Here is

namespace ConsoleApplication5
{
    public class Class1
    {

        static void Main(string[] args)
        {

            String line;
            {
                //Pass the file path and file name to the StreamReader constructor
                StreamReader sr = new StreamReader("data.txt");

                //Read the first line of text
                line = sr.ReadLine();

                //Continue to read until you reach end of file
                while (line != null)
                {
                    //write the line to console window
                    Console.WriteLine(line);
                    //Read the next line
                    line = sr.ReadLine();
                }

                //close the file
                sr.Close();
                Console.ReadLine();
            }
        }
    }
}

What means columnar format?
You mean one value under another?
PS: would you like to have an array of items?

I did what I was thinking you want it to do:

class Program
    {
        static void Main(string[] args)
        {
            Dictionary<string, int> dir = new Dictionary<string, int>();
            using (StreamReader sr = new StreamReader(@"C:\1\testFile.txt"))
            {
                while (!sr.EndOfStream)
                {
                    string line = sr.ReadLine();
                    string[] array = line.Split(',');
                    dir.Add(array[0].ToString(), Convert.ToInt32(array[1]));
                }
            }
            Show(dir);
        }

        private static void Show(Dictionary<string, int> dir)
        {
            foreach (KeyValuePair<string, int> line in dir)
            {
                Console.WriteLine("KEY: {0}, VALUE: {1}", line.Key, line.Value);
            }
            Console.ReadLine();
        }
    }

Hope it helps, if not, let me know.

Hmm regarding your text file, you cannot have integer as the value parameter. Change the int to string (in the dictonary).

like that:

static void Main(string[] args)
        {
            Dictionary<string, string> dir = new Dictionary<string, string>();
            using (StreamReader sr = new StreamReader(@"C:\1\testFile.txt"))
            {
                while (!sr.EndOfStream)
                {
                    string line = sr.ReadLine();
                    string[] array = line.Split(',');
                    dir.Add(array[0], array[1]);
                }
            }
            Show(dir);
        }

        private static void Show(Dictionary<string, string> dir)
        {
            foreach (KeyValuePair<string, string> line in dir)
            {
                Console.WriteLine("KEY: {0}, VALUE: {1}", line.Key, line.Value);
            }
            Console.ReadLine();
        }

... let me know if is it workin, ok?

If this is the error, that means that one of 2 arrays (array[0] or array[1]) but mostly would be array[1] cannot get filled, becuase there is no data for it. Thats means that in the "line" there was no comma (,) and the string couldnt get splitted. There is only one string - but the adding code requires 2 strings.

Please check your file, if there is a comma on EVERY single line.
And please put a break point to go through the code line by line. And tell me exactly when this error occures (which line is in that moment in the streamReader).

Break point is thta red dot, which you put it by clicking on the far left side of the text editor. When code comes to break point, go with pressing F11 line by line.

I'm making a console app that reads data in and writes to the screen. It should come from a delimited text file, the output should be in columnar format (separated neatly in columns)Text Ex.

year,1997, 1998           output: year  1997    1998
date,   Nov.15, Sep.16            date  Nov.15  Sept.16

Text file is delimited. Array, yes.
Maybe something like this:

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            string fileString;

            Console.SetBufferSize(800, 600);

            while ((fileString = Console.ReadLine()) != null)
            {
                string[] fsArray = fileString.Split(',');
                Console.WriteLine("{0, 15} | {1, -70} | {2, 15}", fsArray[0], fsArray[1], fsArray[2]);
            }
        }
    }
}

]An Error message occurred: Index was outside the bounds of the array.

dir.Add(array[0],array[1]);

Is there something wrong with the text file? It is delimited is it not? I'm making the text file more simple. Can you test this? Thanks!

I have tried your text and it works good.
You have to set your own path (full path) to the file. Mine is:@"C:\1\testFile.txt". You set your own.

I have set my own. It's not a path error I'm getting. Look at last error I posted. i do not know why it is not working.

Mitja Bonca 557 Nearly a Posting Maven · Answer 7 · 2010-12-11T03:36:01+00:00

As I said, I have put your text into my file, and it all works fine. No errors at all.
I dont know what can be wrong on our side.

Could this be the problem? Last question sorry.

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

I keep getting that same error-index was outside the bounds of the array, out of range.

I got it! Somehow when I tweaked the old file to make it easier to work with it became my down fall. I recopied the original and it works! My bad, idiot move! Now thats said and done, do you know how to add a count of the number of records following the columnar output. Like count: 25? Thank you!!!

This how:

class Program
    {
        static void Main(string[] args)
        {
            Dictionary<string, string> dir = new Dictionary<string, string>();
            using (StreamReader sr = new StreamReader(@"C:\1\testFile.txt"))
            {
                while (!sr.EndOfStream)
                {
                    string line = sr.ReadLine();
                    string[] array = line.Split(',');
                    dir.Add(array[0], array[1]);
                }
            }
            Show(dir);
        }

        private static void Show(Dictionary<string, string> dir)
        {
            int counter = 0;
            foreach (KeyValuePair<string, string> line in dir)
            {
                Console.WriteLine("KEY: {0}, VALUE: {1}", line.Key, line.Value);
                counter++;
            }
            Console.WriteLine("Total number of records: {0}", counter.ToString());
            Console.ReadLine();
        }
