在mono命令行应用程序中无法使用castle activerecord？

我正在使用Castle activeRecord，我已经成功制作了一个asp.net MVC应用程序，它可以生成模式，执行crud操作并查询mysql数据库。我在MonoDevelop中做过这个。

令人讨厌的是，如果我在命令行项目中使用几乎完全相同的代码，它就不起作用，抛出以下异常：

Could not create the driver from NHibernate.Driver.MySqlDataDriver

在下面的代码中的pc.Create();处抛出异常。即使我告诉它生成模式，这实际上从未发生过，但它确实发生在Web应用程序中。

这条消息的一些谷歌搜索表明当mysql.data.dll文件不在路径或引用等时会发生这种情况。它被引用，并且“本地复制”被启用，因此它被复制到调试文件夹中。我已经检查过它实际上也存在于文件夹中。

我有与asp.net mvc app完全相同的引用。为什么会失败？

以下是命令行app的代码：

using System;
using Castle.ActiveRecord;
using Castle.ActiveRecord.Framework.Config;
using ArTestCmd;

namespace ArTestCmd
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            String configFile = @"/home/si/Projects/ArTestCmd/CastleAR.config";

            XmlConfigurationSource source = new XmlConfigurationSource(configFile);
            ActiveRecordStarter.Initialize(source, typeof(Pc));
            ActiveRecordStarter.UpdateSchema();

            Pc pc = new Pc();
            pc.name = "blah";
            pc.Create();

        }
    }

    [ActiveRecord]
    public class Pc : ActiveRecordBase<Pc>
    {
        [PrimaryKey]
        public int PcId { get; set; }
        [Property (NotNull=true,Unique=true)]
        public String name { get; set; }

    }
}

这是堆栈跟踪：

答案 0 :(得分：0)

想出来。事实证明这是一个区分大小写的问题，它与城堡AR或NHibernate没什么关系。

当我尝试使用没有activeRecord的MySql.Data程序集时，它给了我一个未找到文件的异常，显示程序集名称为MySql.Data.dll。我将dll的名称从mysql.data.dll更改为MySql.Data.dll，并且有效。

为什么程序集继续在asp.net mvc应用程序中运行，所有小写对我来说都是个谜。
