组态 [英] Configuration

问题描述

刚刚看到这段代码：

 Dim config As Configuration 
 config = ConfigurationManager .OpenExeConfiguration（ConfigurationUserLevel.None）
返回config.ConnectionStrings.ConnectionStrings（key）.ConnectionString 

如果我是编译器要求编译它，我会自我破坏并带走我的所有代码！

无论发生什么事情 

 My.Settings.MyConnectionString

解决方案

我认为这里的原因是为了访问配置文件中的多个连接之一，而当只有一个连接时使用My.Settings.SomeConnection。

查看我的MSDN
代码示例，用于一个项目中的多个连接。然后，我的MSDN
代码示例

Just came across this code:

Dim config As Configuration
config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
Return config.ConnectionStrings.ConnectionStrings(key).ConnectionString

If I were a compiler asked to compile that, I would self-destruct and take all your code with me!
Whatever happened to 

My.Settings.MyConnectionString

解决方案

I believe the reason here is for accessing one of many connections in the config file while when there is only one connection we use My.Settings.SomeConnection.

See my MSDN code sample for multiple connections in one project. Then there is sharing connections across projects as shown in my MSDN code sample.
