ASP.NET和MySQL .Net Framework数据提供程序问题

我是ASP.NET的新手.每次我尝试运行我的应用程序时,都会遇到下面的错误消息.我已经多次为 MySQL安装.Net Framework Data Provider.
我希望有人可以帮助我.提前致谢.

Server Error in '/PLDT QuickSearcher' Application.

Unable to find the requested .Net Framework Data Provider.  It may not be installed.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.ArgumentException: Unable to find the requested .Net Framework Data Provider.  It may not be installed.

解决方法

添加MysqL.Data.dll作为项目的参考
将此块添加到web.config：

<system.data>
    <DbProviderFactories>
        <add name="MysqL Data Provider" invariant="MysqL.Data.MysqLClient" description=".Net Framework Data Provider for MysqL" type="MysqL.Data.MysqLClient.MysqLClientFactory,MysqL.Data" />
    </DbProviderFactories>
</system.data>
