SQL Connection in C# - Unity 3D

(Reference: Unity e MySql - YouTube)

1 - I downloaded the Connector / Net (Net & Mono version 2.0.).

2 - Insert the mysql.data.dll the project.

3 - I configured. NET in my project = Edit / Project Settings / Player / Optimization / Api Compatibility Level>. NET 2.0.

4 - I created this script below:

using UnityEngine;
using System.Collections;
using MySql.Data.MySqlClient;

public class ConexaoBanco : MonoBehaviour {
private string source;
private MySqlConnection conexao;


// Use this for initialization
void Start () {
	source = 	  "Server=    fdb1.awardspace.net;" +
		          "Database = 5963_androidbase_1;" +	
			  "User ID =  2222_androide_2;" +
			  "Pooling =  false;" +
		          "Password=  ???";

            / / Or option localhost, but still got error:
	source = 	  "Server=localhost;" +
		          "Database = 5963_androidbase_1;" +	
			  "User ID = root;" +
			  "Pooling = false;" +
		          "Password= ";

	ConexaoBanco(source);
	Listar (conexao);
	
}

// Update is called once per frame
void Update () {
	
}

void ConectarBanco (string _source){
	conexao = new MySqlConnection (_source);
	conexao.Open ();
}

void Listar (MySqlConnection _conexao){
	MySqlCommand comando = _conexao.CreateCommand();
	comando.CommandText = "Select * from voz_principal";
	MySqlDataReader dados = comando.ExecuteReader();

	while (dados.Read()){
		string nome = (string)dados["nome"];

		Debug.Log("Usuario " + nome);

		}

	}

}

I RECEIVED THE FOLLOWING ERROR INSPECTOR OF MONO:

Line 26 says
ConexaoBanco(source);

But ConexaoBanco is the name of your class, not a method.

Maybe you meant

ConectarBanco(source);
