Question

我有以下代码。

 public CuentasCobrarBL(string rutaDatos)
        {
            rutaDirec = new CompanyBL(rutaDatos).rutaDirectorio;
            CompanyBL companybl = new CompanyBL(rutaDatos);
            Compania compania =  companybl.CargarCompania();
}




public ilimitada.Dominio.Pervasive.SCI.Core.Entidades.Compania CargarCompania()
        {
            ilimitada.Dominio.Pervasive.SCI.Core.Entidades.Compania companium = null;
            using (IPervasive<ilimitada.Dominio.Pervasive.SCI.Core.DAO.Estructuras.Compania> pervasive = BtrieveDataProvider<ilimitada.Dominio.Pervasive.SCI.Core.DAO.Estructuras.Compania>.Create(this.rutaDirectorio, 999))
            {
                //    pervasive.DataBuffer = new ilimitada.Dominio.Pervasive.SCI.Core.DAO.Estructuras.Compania();
                //    int num = (ushort)Marshal.SizeOf<ilimitada.Dominio.Pervasive.SCI.Core.DAO.Estructuras.Compania>(new ilimitada.Dominio.Pervasive.SCI.Core.DAO.Estructuras.Compania());
                //    if (pervasive.Open(OpenMode.Normal))
                //    {
                //        if (pervasive.GetFirst())
                //        {
                //            companium = CompaniaCV.ConvertirEstructuraEnObjeto(pervasive.DataBuffer);
                //        }
                //    }
            }
            return companium;
        }

using 行抛出这个异常。

如果我编译解决方案编译没有问题，dll放在bin文件夹下，但是貌似程序找不到。

请帮忙。

您的应用程序是从 bin 目录启动的吗？如果没有，则需要将该库复制到可执行文件所在目录。
