问题描述
我有一个包含包含一个连接字符串，应用程序配置文件控制台应用程序如下图所示：
I have a console app containing an application configuration file containing one connection string as shown below:
<configuration>
<connectionStrings>
<add name="Target"
connectionString="server=MYSERVER; Database=MYDB; Integrated Security=SSPI;" />
</connectionStrings>
</configuration>
当我使用它传递给我的连接方式：
When I pass this to my Connection using:
ConfigurationManager.ConnectionStrings[1].ToString()
我有两个值在那里，因此使用集合中的第二个，我的问题是，什么是第二次来的？
I have two values in there, hence using the second in the collection, my question is where is this second coming from?
我已经检查了\\ BIN的版本和原来和我无关！它显然是一个系统生成的一个，但我还没有见过这个？任何人都可以告诉我吗？
I have checked the \Bin version and original and its not mine! Its obviously a system generated one but I have not seen this before? Can anyone enlighten me?
神秘的连接字符串是：
data source=.\SQLEXPRESS;
Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;
User Instance=true
这是不是一个问题，因为这样我只是想知道这是为什么出现？在此先感谢！
This isn't a problem as such I would just like to know why this is occuring? Thanks in advance!
有关备查那些谁可能会或可能不会在这个绊倒，发现了的machine.config ，它变得很明显这是不好的做法，通过指一个配置后，其作为每个堆栈索引将可能是不同的，这就是为什么密钥被使用。
For future reference to those who may or may not stumble on this, after discovering the machine.config, it's become apparent it is bad practice to refer to a config by its index as each stack will potentially be different, which is why "Keys" are used.
在这种情况下我的code将是：
In this instance my code would be:
ConfigurationManager.ConnectionStrings["Target"].ToString()
干杯所有！
推荐答案
检查的machine.config 。如果你只想要你进入，你可以添加一个＆LT;清/＆GT; 元素添加到＆LT;是connectionStrings＆GT; 像这样的元素...
Check your machine.config. If you only want your entry, you can add a <clear /> element to the <connectionStrings> element like so ...
<connectionStrings>
<clear />
<add name="Target"
connectionString=
"server=MYSERVER; Database=MYDB; Integrated Security=SSPI;" />
</connectionStrings>
