Need some Guidance comparing to listboxes on a windows forms

Rudy Escamilla

I have created a GUI (Windows Form) that has FileBrowserdialogs in which you can choose the folder and display the contents on each listbox respectively. However, I want to compare both list boxes and display the differences in the strings on the third list box by pressing a button. For example:

List Box 1

(XXXX_YYYY_ZZZZ_4R_5KL_CM12345_L_88%_0.01_v1)

List Box 2

(XXXX_YYYY_ZZZZ_4R_5KL_CM12346_L_90%_0.01_v1)

Usually, the string will have changes in the highlighted area but the unhighlighted area will have the same text for each item. I am new to C# so any

help would be much appreciated. Below is my code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.IO;

namespace WindowsFormsApplication3

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

FolderBrowserDialog FBD = new FolderBrowserDialog();

if (FBD.ShowDialog() == DialogResult.OK)

{

listBox1.Items.Clear();

string[] files = Directory.GetFiles(FBD.SelectedPath);

string[] dirs = Directory.GetDirectories(FBD.SelectedPath);

foreach (string file in files)

{

listBox1.Items.Add(file);

}

foreach (string dir in dirs)

{

listBox1.Items.Add(dir);

}

private void button2_Click(object sender, EventArgs e)

{

FolderBrowserDialog FBD = new FolderBrowserDialog();

if (FBD.ShowDialog() == DialogResult.OK)

{

listBox2.Items.Clear();

string[] files = Directory.GetFiles(FBD.SelectedPath);

string[] dirs = Directory.GetDirectories(FBD.SelectedPath);

foreach (string file in files)

{

listBox2.Items.Add(file);

}

foreach (string dir in dirs)

{

listBox2.Items.Add(dir);

}

{

}

private void button3_Click(object sender, EventArgs e)

{

}

Hello Sujeet,
I received the string (collection) on the third listbox instead of the differences between both.

Here is the full code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.IO;

namespace WindowsFormsApplication3

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)

        {

            FolderBrowserDialog FBD = new FolderBrowserDialog();

            if (FBD.ShowDialog() == DialogResult.OK)

            {

                listBox1.Items.Clear();

                string[] files = Directory.GetFiles(FBD.SelectedPath);

                string[] dirs = Directory.GetDirectories(FBD.SelectedPath);

                foreach (string file in files)

                {

                    listBox1.Items.Add(file);

                }

                foreach (string dir in dirs)

                {

                    listBox1.Items.Add(dir);

                }

            }

        }

        private void button2_Click(object sender, EventArgs e)

        {

            FolderBrowserDialog FBD = new FolderBrowserDialog();

            if (FBD.ShowDialog() == DialogResult.OK)

            {

                listBox2.Items.Clear();

                string[] files = Directory.GetFiles(FBD.SelectedPath);

                string[] dirs = Directory.GetDirectories(FBD.SelectedPath);

                foreach (string file in files)

                {

                    listBox2.Items.Add(file);

                }

                foreach (string dir in dirs)

                {

                    listBox2.Items.Add(dir);

                }

            }

            {

            }

        }

        private void button3_Click(object sender, EventArgs e)

        {

            for (int intCount = 0; intCount < listBox1.Items.Count; intCount++)

            {

                for (int intSubCount = 0; intSubCount < listBox2.Items.Count; intSubCount++)

                {

                    string s1 = listBox1.Items[intCount].ToString();

                  string s2 = listBox2.Items[intSubCount].ToString();

                    IEnumerable<string> set1 = s1.Split('_').Distinct();

                    IEnumerable<string> set2 = s2.Split('_').Distinct();

                    if (set2.Count() > set1.Count())

                    {

                        listBox3.Items.Add(set2.Except(set1).ToList());

                    }

                }

                {

                }

            }

        }

    }

}

Rudy please once try below code:

private void button3_Click(object sender, EventArgs e)
{
   for (int intCount = 0; intCount < listBox1.Items.Count; intCount++)
   {
      for (int intSubCount = 0; intSubCount < listBox2.Items.Count; intSubCount++)
      {
         string s1 = listBox1.Items[intCount].ToString();
         string s2 = listBox2.Items[intSubCount].ToString();

         IEnumerable set1 = s1.Split('_').Distinct();
         IEnumerable set2 = s2.Split('_').Distinct();.

         if (set2.Count() > set1.Count())
         {
            listBox3.Items.Add(set2.Except(set1).ToList();
         }
      }
   }
}
