这可能对你有用：

    MySql.Data.MySqlClient.MySqlConnection connection;
        string server = "localhost";
        string database = "weather";
        string uid = "db1";
        string password = "db12121";
        string connectionString;
        connectionString = "SERVER=" + server + ";" + "DATABASE=" +
        database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";

    try
        {
            connection.Open();
            if (connection.State == ConnectionState.Open)
            {
                MySqlCommand cmd = new MySqlCommand("insert into forecast (country,city,temperature) values(@Country,@City,@Temperature)", connection);
                cmd.Parameters.AddWithValue("@Country", country1);
                cmd.Parameters.AddWithValue("@City", city1);
                cmd.Parameters.AddWithValue("@Temperature", temperature);
                cmd.ExecuteNonQuery();
            }
            else
            {
                DisplayMessage.Text = "Database connection failed.";
            }


        }
        catch (Exception ex)
