如何创建动态连接字符串？ [英] how to create Dynamic connection string?

问题描述

我收到错误，因为''无法为文件附加自动命名数据库：d：\ new folder \a.mdf''。

当我在其他PC上运行我的项目设置时会发生此错误。是否有任何解决方案来创建动态conectionString，以便当我将我的设置提供给任何人时它应该没有错误？

也我收到错误因为无法打开登录请求的数据库sample.mdf。登录失败。



请尽快帮助我..

推荐答案

你可以使用应用程序启动路径。安装应用程序时的意思是使用路径。





快乐编码：）

u can use application Start up path. meant use path when your application is installed.


Happy Coding :)

string DPath=Application.StartupPath + "\\xyz.mdb"

string ConString = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=" + DPath ;

OleDbConnection cnn = new OleDbConnection(ConString);
