C# Azure MySql异常：连接字符串可能不正确。请访问门户网站以获取参考

从.net framework应用程序到Azure MySql服务器的MySql连接有问题

错误是

MySql.Data.MySqlClient.MySqlException
  HResult=0x80004005
  Message=Authentication to host 'myserver-mysql.mysql.database.azure.com' for user 'username@myserver-mysql' using method 'mysql_native_password' failed with message: The connection string may not be right. Please visit portal for references.
  Source=MySql.Data

用于重现问题的控制台应用程序

    static void Main(string[] args)
    {
        var server = "myserver-mysql.mysql.database.azure.com";
        var database = "e10bf91fc2a8e281d06fecf752e2a592";
        var user = "username@myserver-mysql";
        var password = "mypassword";
        var port = "3306";
        var sslM = "preferred";

        var connectionString = String.Format("server={0};port={1};user id={2}; password={3}; database={4}; SslMode={5}", server, port, user, password, database, sslM);

        using (var connection = new MySqlConnection(connectionString))
        {
            connection.Open();

            connection.Ping();
        }

        Console.ReadKey();
    }

包裹

<packages>
  <package id="Google.Protobuf" version="3.5.1" targetFramework="net472" />
  <package id="MySql.Data" version="8.0.15" targetFramework="net472" />
</packages>

我还从Azure门户尝试了完全相同的连接字符串

$”Server=myserver-mysq.mysql.database.azure.com；Port=3306；database={database}；Uid=username@myserver-mysq；Pwd={password}；SslMode=Preferred；“但没有机会

有人能告诉我我缺少什么吗？
试试这种连接字符串格式：

var connectionString = String.Format("Server={0};Port={1};Uid={2};Pwd={3};Database={4};SslMode={5}", server, port, user, password, database, sslM);

请尝试此连接字符串格式：

var connectionString = String.Format("Server={0};Port={1};Uid={2};Pwd={3};Database={4};SslMode={5}", server, port, user, password, database, sslM);

谢谢，但那也没用。我用Bradley Grainger的MySqlConnector替换了MySql.Data包，从而使它能够正常工作。遗憾的是，最后一个没有EF包，所以我要么找到一个修复程序，要么创建我的own@xakz我不确定Oracle的MySql.Data是否与Azure Database for MySql兼容。如果您可以使用EF.Core，那么应该适合您。否则，MySqlConnector上没有构建“经典”的EF实现，抱歉。谢谢，但这也没有帮助。我用Bradley Grainger的MySqlConnector替换了MySql.Data包，从而使它能够正常工作。遗憾的是，最后一个没有EF包，所以我要么找到一个修复程序，要么创建我的own@xakz我不确定Oracle的MySql.Data是否与Azure Database for MySql兼容。如果您可以使用EF.Core，那么应该适合您。否则，很抱歉，MySqlConnector上没有构建“经典”EF实现。
