About

MySQL provides connectivity for client applications developed in .NET compatible programming languages with MySQL Connector/NET through a series of packages.

MySql.Data is the core package of Connector/NET. It is compatible with .NET Framework 4.6+ and .NET 6.0+ and provides classic MySQL protocol and MySQL X DevAPI capabilities.

More information at MySQL Connector/NET documentation.

How to use

    MySql.Data.MySqlClient.MySqlConnection myConnection;
    string myConnectionString;
    //set the correct values for your server, user, password and database name
    myConnectionString = "server=127.0.0.1;uid=root;pwd=12345;database=test";

    try
    {
      myConnection = new MySql.Data.MySqlClient.MySqlConnection(myConnectionString);
      //open a connection
      myConnection.Open();

      // create a MySQL command and set the SQL statement with parameters
      MySqlCommand myCommand = new MySqlCommand();
      myCommand.Connection = myConnection;
      myCommand.CommandText = @"SELECT * FROM clients WHERE client_id = @clientId;";
      myCommand.Parameters.AddWithValue("@clientId", clientId);

      // execute the command and read the results
      using var myReader = myCommand.ExecuteReader()
      {
        while (myReader.Read())
        {
          var id = myReader.GetInt32("client_id");
          var name = myReader.GetString("client_name");
          // ...
        }
      }
      myConnection.Close();
