windows 通用 连接远程数据库

Question

写了个uwp程序，要用到数据库，于是申请了google cloud sql，在cmd里也可以成功的操作此数据库:
但是在visual studio里用C#时就连接不上，一直提示这个错误：引发的异常:“MySql.Data.MySqlClient.MySqlException”(位于 MySql.Data.RT.dll 中)
MySqlConnection mc = new MySqlConnection();代码：
MySqlConnectionStringBuilder s = new MySqlConnectionStringBuilder();
s.Server = "146.148.112.96";

s.UserID = "root";
s.Database = "Bridge";
s.Password = "19901031";
mc.ConnectionString = s.ToString();
try
{
mc.Open();
MySqlCommand cmd = new MySqlCommand();
cmd = mc.CreateCommand();
cmd.CommandText = "select * from userInfo where name='" + usertextBox.Text + "' where nikyname='" + nicktextBox1.Text + "'";
MySqlDataReader mdr = cmd.ExecuteReader();
mdr.Read();
if (mdr.HasRows)
{
MessageDialog msg = new MessageDialog("Username/Nickname invalid!");
await msg.ShowAsync();
insert = false;
}
else
{
insert = true;
}
mc.Close();
}

哪位大神帮忙指导下，谢啦

端口号是3306么？端口号、用户名、密码是否正确。
