我正在尝试在我的本地环境中执行以下代码片段并且它工作正常。但是当我尝试在更高的环境中执行时，例如在其他系统中，我遇到了运行时错误。以下是一段代码。我我正在使用企业库 5。

internal static DataTable Users()
        {
            DataSet Users = null;
            string sqlStmt = ConfigurationManager.AppSettings["anyKey"];
            try
            {
                Database database = DatabaseFactory.CreateDatabase("Dbname");
                DbCommand command = database.GetSqlStringCommand(sqlStmt);
                using (command)
                {
                    Users = database.ExecuteDataSet(command);
                }
            }
            catch (Exception ex)
            {
                LoggerHelper.LogInformation("Error occured getting value");
                LoggerHelper.LogException(ex);
            }
            return dbname.Tables[0];

我得到的错误是：

我已经检查了有关 dll 的所有内容。你能帮我一些替代解决方案吗
