Question

我正在尝试使用通过NuGet安装的MySQL Connector / NET 6.9.9将Golang / MySQL应用程序移植到C＃/ MySQL应用程序。我的用于验证MySQL连接的测试应用程序非常简单：

        string connStr = "server=192.168.5.3; protocol=tcp; pooling=false; uid=pdanuser; database=pdan; port=3306; pwd=<redacted>;";
        MySqlConnection conn = new MySqlConnection(connStr);
        try
        {
            Console.WriteLine("Connecting to MySQL...");
            conn.Open();

            string sql = "SELECT <redacted> FROM <redacted> limit 100";
            MySqlCommand cmd = new MySqlCommand(sql, conn);
            MySqlDataReader rdr = cmd.ExecuteReader();

            while (rdr.Read())
            {
                Console.WriteLine(rdr[0] + " -- " + rdr[1]);
            }
            rdr.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
        conn.Close();
        Console.WriteLine("Done.");

我收到以下错误：

Connecting to MySQL...

Done.

我知道我没有网络或身份验证问题，因为Golang应用程序使用相同的用户名和密码在同一个MySQL数据库上成功运行。我已经搜索了这个错误并看到了有关卸载和重新安装MySQL Connnector的一些建议，但这些都没有对我有用。任何建议都会非常受欢迎。
