COM类工厂错误

Question

我在控制台应用程序中尝试显示，由于以下错误，检索CLSID {00024500-0000-0000-C000-000000000046}组件的COM类工厂失败：80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

这是错误。如何解决这个问题：

static void Main(string[] args)
    {


        StringBuilder query = new StringBuilder();
        query.Append("SELECT deptId ");
        query.Append(",[deptabbr], [deptname ], [deptnameLocal] ");
        query.Append(",[deptabbrLocal ]");
        //    , [UnitPrice], [UnitsInStock] ");
        //query.Append(",[UnitsOnOrder], [ReorderLevel], [Discontinued] ");
        query.Append("FROM [dbo].[mDepartment] ");
        //query.Append("JOIN Categories ON Categories.CategoryID = Products.CategoryID ");
        //query.Append("ORDER BY Categories.CategoryName ");
