To demonstrate the simplicity of use and adaptability of dotConnect for MySQL in real-world applications, let’s now get into a practical example to see how it works by creating connections and carrying out queries. The purpose of this example is to walk you through the fundamental steps involved in implementing dotConnect for MySQL into your projects from start to finish.
Example of Connection with MySQL in .NET Application
An example of a Windows form will be shown below. This example will demonstrate how we will enter data about students, such as the student’s name, age, section, and roll number. This information will be inserted into the respective text boxes. Immediately after the addition of data, we will display this data on a dataGridView.
Create Windows From
To begin, we will develop a Windows form that will allow users to submit information about students. To do this, please follow the steps given below:
- Create a new Windows Forms project in Visual Studio and give it a meaningful name.
- Now, search for Label, TextBox, Button, and a DataGridView using the left panel of the ToolBox.
- Simply move the items to the windows form by dragging and dropping them, and arranging them accordingly.
- It is necessary for you to provide each component with a relevant name that will be used to carry out actions via the component.
Add dotConnect for MYSQL NuGet Package
In the Solution Explorer, right-click on the Solution option, and click on Manage NuGet Packages for Solution… from the menu bar.
A new small window will appear. From the left panel, search dotConnect MySQL and then find dotConnect.Express.for.MySQL from the list, check the checkbox in the right-side small window and click on Install.
At this point, we have finished creating our Windows form, and it is time to write code to perform the desired tasks.
I’ll create a table named Students having Name, Age, Section, and Rollno as attributes in a database named StdExample. I am using MySQL Console in WampServer.
Or, If you are using MariaDB, you can follow the commands below and create a database and required table with attributes as below:
Let’s begin with the code:
Double-click on the Add the Student button on the Windows Form we created before to generate an event against it, here we’ll write all our code.
To begin, import the following libraries.
| using System; using Devart.Data.MySql; using System.Data; using System.Windows.Forms; |
Then, create variables of MySqlConnection, MySqlCommand, MySqlDataAdapter, and Dataset and name them connection, cmd, da, and ds respectively.
| public partial class Form1 : Form { private MySqlConnection connection; private MySqlCommand cmd; private MySqlDataAdapter da; private DataSet ds; } |
Initialize the database using your connection string, MySqlConnection, and MySqlCommand.
| private void InitializeDatabase() { string connectionString = @”Data Source=DESKTOP-F1SA8LE;Initial Catalog=StdExample; User Id=root;Password=;”; connection = new MySqlConnection(connectionString); cmd = new MySqlCommand(); connection.Open(); cmd.Connection = connection; cmd.CommandType = CommandType.Text; } |
Now, we’ll save inputs from textboxes to their relevant variables. Pass these variables to the database with the help of the Insert query, and then refresh dataGridView to reload newly added
| data using LoadStudentData(). private void AddStudentbtn_Click(object sender, EventArgs e) { // Add a new student to the database string name = txtName.Text; int age = Convert.ToInt32(txtAge.Text); string section = txtSection.Text; int rollno = Convert.ToInt32(txtRollno.Text); string insertQuery = $”INSERT INTO Students (Name, Age, Section, Rollno) VALUES (‘{name}’, {age},'{section}’,{rollno})”; cmd.CommandText = insertQuery; cmd.ExecuteNonQuery(); // Reload data to update DataGridView LoadStudentData(); // Clear input fields txtName.Text = “”; txtAge.Text = “”; txtSection.Text = “”; txtRollno.Text = “”; } |
Lastly, we’ll fill dataGridView with the Student data using the Select query.
| private void LoadStudentData() { // Load student data from the database string query = “SELECT * FROM Students”; da = new MySqlDataAdapter(query, connection); ds = new DataSet(); da.Fill(ds, “Students”); // Display data in DataGridView dataGridView1.DataSource = ds.Tables[“Students”]; } |
Now, Run the project, and add the student details to the Windows form.
After you click on the Add Student Button, The data will be loaded into the dataGridView.

| using System; using Devart.Data.MySql; using System.Data; using System.Windows.Forms; namespace dotConnet_for_MySql_example { public partial class Form1 : Form { private MySqlConnection connection; private MySqlCommand cmd; private MySqlDataAdapter da; private DataSet ds; public Form1() { InitializeComponent(); InitializeDatabase(); LoadStudentData(); } private void InitializeDatabase() { string connectionString = @”Data Source=DESKTOP-F1SA8LE;Initial Catalog=StdExample; User Id=root;Password=;”; connection = new MySqlConnection(connectionString); cmd = new MySqlCommand(); connection.Open(); cmd.Connection = connection; cmd.CommandType = CommandType.Text; } private void AddStudentbtn_Click(object sender, EventArgs e) { // Add a new student to the database string name = txtName.Text; int age = Convert.ToInt32(txtAge.Text); string section = txtSection.Text; int rollno = Convert.ToInt32(txtRollno.Text); string insertQuery = $”INSERT INTO Students (Name, Age, Section, Rollno) VALUES (‘{name}’, {age},'{section}’,{rollno})”; cmd.CommandText = insertQuery; cmd.ExecuteNonQuery(); // Reload data to update DataGridView LoadStudentData(); // Clear input fields txtName.Text = “”; txtAge.Text = “”; txtSection.Text = “”; txtRollno.Text = “”; } private void LoadStudentData() { // Load student data from the database string query = “SELECT * FROM Students”; da = new MySqlDataAdapter(query, connection); ds = new DataSet(); da.Fill(ds, “Students”); // Display data in DataGridView dataGridView1.DataSource = ds.Tables[“Students”]; } } } |
