问题描述

我正在尝试使用FirebirdSQL .net提供程序(使用FirebirdSql.Data.FirebirdClient)连接并从Firebird数据库读取数据.这是代码:

I am trying to connect and read data from Firebird database using the FirebirdSQL .net provider (using FirebirdSql.Data.FirebirdClient). Here is the code:

FbConnection viewdataConnection=new FbConnection();
viewdataConnection.ConnectionString = "database=localhost:c:\\firebirdTest\\testDB.fdb;user=sysdba;password=firebird";
viewdataConnection.Open();

尝试打开()连接时，出现错误:

While trying to Open() the connection, i get an error:

An unhandled exception of type 'FirebirdSql.Data.FirebirdClient.FbException' occurred in FirebirdSql.Data.FirebirdClient.dll
Additional information: Error occurred during login, please check server firebird.log for details

推荐答案

如果您需要以应用程序模式运行Firebird服务器，请以管理员身份运行它.

If you need to run the Firebird server in application mode, run it as administrator.

这为我解决了问题.Firebird服务器需要对安装文件夹中的某些文件具有写权限.

This solved the problem for me. The Firebird server needs write access to some files in the installation folder.
