c# - 异常信息是 'Could not load file or assembly ' MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d'?

Question

我尝试部署一个简单的 wcf 服务，该服务与 mysql5.7 数据库连接，通过错误将其服务器上，但是当我运行到我的本地机器时，相同的应用程序运行正常(我的本地机器也有一个 mysql5.7 数据库)。 7 数据库)我不知道为什么会出现这个错误。

我已经准备好添加 Mysql.Data.dll 6.9.9.0;

错误是:

服务器在处理请求时遇到错误。异常信息是

'Could not load file or assembly 'MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified.'. See server logs for more details

应用程序下连接数据库和向数据库插入数据的简单方法；

 public class MyNameService : IMyNameService
    {


        public string nameInput(string input, string inputwo)
        {
            string myDataString = "Server=localhost;Database=foo;Uid=root;Pwd=qwerty;";

            MySqlConnection connection = new MySqlConnection(myDataString);
            MySqlCommand cmd;
            connection.Open();
            try
            {
                cmd = connection.CreateCommand();
                cmd.CommandText= "INSERT INTO foo.footable (id,name,lastName) VALUES (@id,@name,@lastName)";
                cmd.Parameters.AddWithValue("@id", int.Parse(3.ToString()));
                cmd.Parameters.AddWithValue("@name", input);
                cmd.Parameters.AddWithValue("@lastName", inputwo);
                cmd.ExecuteNonQuery();
                connection.Close();
            }
