Vsto引用Mysql.data.dll出现未定义错误

wjb305945078

在利用Vsto开发Word的Com加载项时，需利用mysql，我已添加mysql.data.dll程序集引用，且代码中如下：Imports MySql.Data.MySqlClient
sub  Ceshi()
            Dim MyConn As New MySqlConnection
            Dim MyCmd As New MySqlCommand
            Dim MyRead As MySqlDataReader

……
end sub
编译过程中出现：warning BC40056: Namespace or type specified in the Imports 'MySql.Data.MySqlClient' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

error BC30002: Type 'MySqlConnection' is not defined.请问如何解决呢？谢谢大家！

找到原因了，对于vsto模块里面引用mysql不能在上方添加 Imports MySql.Data.MySqlClient
