C# 连接到PHPMyAdmin托管的数据库

我正在尝试将一个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");

以下是此失败调用的结果：

有人能理解吗？因为这对我来说几乎毫无意义

您使用了错误的类，需要获取ADO.NET MySQL库并使用

MySqlConnection

。

那么此行希望连接到哪种类型的数据库？@renegadendy，代码中的连接字符串是

MySQL

服务器，

SqlConnection

正在尝试连接到Microsoft SQL Server。
