c# and mysql connection code example

Example 1: c# mysql query

MySqlConnection con = new MySqlConnection(connectionString);
con.Open();
MySqlCommand cmd = new MySqlCommand("SELECT * FROM customers",con);
MySqlDataReader reader = cmd.ExecuteReader();
	while (reader.Read())
	{
    	//You can get values from column names
    	Console.WriteLine(reader["customerName"].ToString());
      	//Or return the value from the columnID, in this case, 0
    	Console.WriteLine(reader.GetInt32(0));
	}
con.Close();

Example 2: test mysql connection

Example (MySQLi Object-Oriented)
<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>

Example (MySQLi Procedural)
<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = mysqli_connect($servername, $username, $password);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>

Example (PDO)
<?php
$servername = "localhost";
$username = "username";
$password = "password";

try {
    $conn = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully";
    }
catch(PDOException $e)
    {
    echo "Connection failed: " . $e->getMessage();
    }
?>
