Follow the steps 1)Install the MySQL Connector/NET using NuGet Package Manager: 2) C# code using System; using MySql.Data.MySqlClient; namespace MySQLDataRetrieval { class Program { static void Main(string[] args) { // Replace the placeholders with your MySQL server details string connectionString = "your connection string here"; // Step 3: Write C# Code using (MySqlConnection connection = new MySqlConnection(connectionString)) { try { connection.Open(); // SQL query to retrieve data string query = "SELECT * FROM your_table_name;"; MySqlCommand command = new MySqlCommand(query, connection); MySqlDataReader reader = command.ExecuteReader(); while (reader.Read()) { // Access the data using reader methods based on the data types int id = reader.GetInt32("id"); string name = reader.GetString("name"); int age = reader.GetInt32("age"); // Do something with the retrieved data Console.WriteLine($"ID: {id}, Name: {name}, Age: {age}"); } reader.Close(); } catch (Exception ex) { Console.WriteLine("Error: " + ex.Message); } } } } }
