Sådan læser du visse data fra mysql-resultater i C#

Du skal bruge en DataReader til at iterere gennem posterne, i stedet for at bruge cmd.ExecuteNonQuery(); brug cmd.ExecuteReader();

try 
  { 
    MySqlDataReader myReader = cmd.ExecuteReader(); 

    // Always call Read before accessing data. 
    while (myReader.Read())  
    { 
      //This will get the value of the column "name"
      Console.WriteLine(myReader.GetString(myReader.GetOrdinal("name"))); 
    } 

    // always call Close when done reading. 
    myReader.Close(); 

    // Close the connection when done with it. 
    } 
  finally 
  { 
    con.Close(); 
  }
