I want to add a file in my project that is global to my project (database connection file). So, if I make a change to the connection string in that file, the change will affect all code that uses that connection string.

推荐答案

将连接字符串存储在您的

Store the connection string in your project settings.

What I like to do is store several connection strhings in the project settings, then have another setting that indicates which of those settings to pick from. Makes debugging easier, as you can switch connection strings without having to store them somewhere else.

首先，您需要指出是否正在使用Windows Forms(最有可能)，ASP .net(可能性较小)或WPF(可能性最小).其次，我发送给您的链接向您展示了如何使用设置... 逐步.阅读.

First of all, you need to indicate if you are working with Windows Forms (most likely), ASP.net (less likely), or WPF (least likely). Second of all, that link I sent you shows you how to use settings... step by step. Read it.
