Writing Data to CSV File using C#

Step 1: Create New Project

Step 2: Add “System.IO” namespace.

Step 3: Create the form as follows.

Step 4: Write the following code.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.IO;

namespace WritingCSV

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void buttonAdd_Click(object sender, EventArgs e)

{

string FirstName = textBoxFirstName.Text;

string LastName = textBoxLastName.Text;

string Age = textBoxAge.Text;

listBoxFirstName.Items.Add(FirstName);

listBoxLastName.Items.Add(LastName);

listBoxAge.Items.Add(Age);

textBoxFirstName.ResetText();

textBoxLastName.ResetText();

textBoxAge.ResetText();

}

private void buttonWrite_Click(object sender, EventArgs e)

{

string FilePath = textBoxFilePath.Text;

string[] FirstNames = new string[listBoxFirstName.Items.Count];

string[] LastNames = new string[listBoxFirstName.Items.Count];

string[] Ages = new string[listBoxFirstName.Items.Count];

string[] TotalData = new string[listBoxFirstName.Items.Count];

for (int i = 0; i < listBoxFirstName.Items.Count; i++)

{

FirstNames[i] = listBoxFirstName.Items[i].ToString();

LastNames[i] = listBoxLastName.Items[i].ToString();

Ages[i] = listBoxAge.Items[i].ToString();

TotalData[i] = FirstNames[i] + "," + LastNames[i] + "," + Ages[i];

}

File.WriteAllLines(FilePath, TotalData);

MessageBox.Show("CSV File Created Successfully", "Success");

}

Step 5: Output
