我正在尝试将 C# 应用程序连接到本地使用 PHPMyAdmin 创建的 WAMP 托管 MySQL 服务器。
我正在使用以下连接字符串:
sqlConnection = new SqlConnection("server=tcp:127.0.0.1,3306;Database=mydb;uid=root");
以下是此次失败调用的结果:
-> Database Connection Failed!
Exception Caught: Internal connection fatal error.

任何人都可以理解这一点 - 因为这对我来说几乎没有任何意义!
最佳答案
您使用了错误的类，您需要获取 ADO.NET MySQL 库并改用 MySqlConnection。
