使用Xamarin的MySqlWorkbench DB没有.open（）;

Question

我已经使用MySqlWorkbench制作了sql数据库，并试图使连接抛出Xamarin，并在“ .open（）;”处不断出错。部分。

我尝试以各种在线方式建立连接-这些都没有用。

    private const string SERVER= "localhost";        
    private const string DATABASE = "ReDB";
    private const string UID = "root";
    private const string PASSWORD = "root";
    private static MySqlConnection dbConnect;
    public void AddUserDB(User newUser)
    {
        MySqlConnectionStringBuilder builder = new MySqlConnectionStringBuilder();
        builder.Server = SERVER;
        builder.UserID = UID;
        builder.Password = PASSWORD;
        builder.Database = DATABASE;
        string connString = builder.ToString();
        dbConnect = new MySqlConnection(connString);
        string query= "INSERT INTO UserDB (...);
        MySqlCommand cmd = new MySqlCommand(query,dbConnect); 
        dbConnect.Open();
        cmd.ExecuteNonQuery();
        dbConnect.Close();

    MySqlCommand cmd;
    public DatabaseT1()
    {
        dbConnect = new MySqlConnection("Server=localhost;User=root;Database=ReDB;Port=3306;Password=root");
        cmd = new MySqlCommand();
    }

    public void AddUserDB(User newUser)
    {
        dbConnect.Open();
        cmd.Connection = dbConnect;
        cmd.CommandText = "INSERT INTO UserDB (...);
        cmd.ExecuteNonQuery();
        dbConnect.Close();
    }    

。

`Error`      
System.TypeInitializationException: <Timeout execeeded getting exception details>    

-如何彻底解决此问题？> 谢谢：）
