C# .NET 3.0 c mysql连接器在本地计算机上不工作

在本地服务器Machine上运行应用程序时出现问题。 在服务器上，我安装了.NET3.0，并在外部PC上开发了.NET3.0

主要问题是MySQL连接打开，因为在服务器上，当连接打开时，本地MySQL会出现异常，但在我的externaldev pc上，它工作正常，我使用不同的连接登录和传递来建立我的conn，bouth conn信息工作原理与我在bouth机器上使用php脚本检查的一样，我的MySQL connector.dll版本是6.5.4 v2，在外部机器上，应用程序运行良好，但在康涅狄格州的内部服务器上，应用程序是开放的；我得到了一个例外：

异常消息：

第80行：连接打开

很抱歉，忘了提到应用程序以前工作过，但它必须在sql中更改。DEV PC是Win7 64位，服务器是Microsoft windows Server 2003 32位；此操作仅在Windows 2000 SP3或更高版本的操作系统上受支持这可能是原因？@SonerGönül:但是.NET 3是否在早于W2k的系统上运行？很抱歉忘了提到应用程序以前工作过，但它必须在sql中更改。DEV PC是Win7 64位，服务器是Microsoft windows Server 200332bit@PatrickHofman你似乎是对的。Windows 2000仅支持.NET Framework 2.0。确实没有弄乱64/32位版本吗？
