使用库进行连接时，我应该在C#应用程序的哪里编写Connectionstring? [英] Where should i write Connectionstring in C# application while using Library for Connection?

问题描述

我在名为DBConnection的项目中使用连接库，并在另一个库中调用此库，而在Windows应用程序中调用了第二个库
一世. e. 3层架构.因此，问题在于如何在库中添加App.config以及如何在库的类中读取该连接字符串.

我的项目依存关系如下.
DBConnection --To-- DAL库-To-- BAL --To-MyApplication

我是刚开始从事此工作的人，请给我解决方案.
我也想在应用程序数据文件夹中添加我的sqlserver数据库以进行部署，因此再次出现问题，即它如何连接到客户端的服务器，并且它会自动使用我的连接吗?

请有人帮我.

在Advance中致谢

推荐答案

配置信息通常是在应用程序启动时设置的，并且由于它经常更改，因此该信息位于最高级别，即应用程序可执行文件. br/>
您还可以通过文件访问来读取dll级别的配置信息，而您的应用程序可能不知道.

读取配置数据的最简单方法是Dataset.ReadXml().

Configuration information is usually set on the applications startup, and because it is changed often this is put at the highest level, ie the application executable.

You can also read configuration information at the dll level via file access, and your application can have no knowledge.

The simplest way to read config data is Dataset.ReadXml().

App.Config是存储连接字符串的位置.

App.Config is a location where you could store the connection string.
