我已经使用 Rhino-ETL 一段时间了，它运行得非常顺利。但是我在连接到我的 MySQL 数据库时遇到问题。

Rhino.Etl.Core.RhinoEtlException: Failed to execute operation Hornalen.Migration
.Process.ReadMessagesFromDb: The type name 'MySql.Data.MySqlClient' could not be
 found for connection string: testConnectionString ---> System.InvalidOperationE
xception: The type name 'MySql.Data.MySqlClient' could not be found for connecti
on string: testConnectionString
   at Rhino.Etl.Core.Infrastructure.Use.Connection(String name)
   at Rhino.Etl.Core.Operations.InputCommandOperation.<Execute>d__0.MoveNext()

   --- End of inner exception stack trace ---

http://dev.mysql.com/downloads/connector/net/6.1.html mysql.data 被引用并位于我的 bin 文件夹中

我的连接字符串 i app.config 看起来像

    <add name="testConnectionString" connectionString="server=localhost;user id=dev;password=xxxxx;persist security info=True;Database=test"
providerName="MySql.Data.MySqlClient" />

连接字符串在一个简单的网站中工作正常，用于调试目的，作为数据源。我正在运行 asp.net 3.5、win 7 和 VS 2008，如果能在这个问题上提供任何帮助，我将不胜感激。

ETL 项目中的一个简单测试也有效

            MySql.Data.MySqlClient.MySqlConnection connection = new MySqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString);
        connection.Open();
        MySqlCommand command = connection.CreateCommand();
        command.CommandText = "select * from arter";
        MySqlDataReader reader = command.ExecuteReader();
        while (reader.Read())
        {
            System.Console.WriteLine(reader.GetInt32("artId"));    
        }
        connection.Close();

在使用 Type.GetType("xxx") 后，它开始使用“MySql.Data.MySqlClient.MySqlConnection, MySql.Data”，然后重新建议“修复模块资格”

<add name="testConnectionString" connectionString="server=localhost;user id=dev;password=xxxxx;persist security info=True;Database=test"
providerName="MySql.Data.MySqlClient.MySqlConnection, MySql.Data, Version=6.1.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
