问题描述
我在.NET 2.0项目中使用内的app.config文件中的的ConnectionStrings 部分。在配置部分包含我已经定义了两个连接字符串。
I'm using a connectionStrings section within an app.config file in a .NET 2.0 project. The config section contains two connection strings I have defined.
当我取回 ConnectionStringSettingsCollection 它有3计数第0项是SQLEx preSS
When I retrieve the ConnectionStringSettingsCollection it has a count of 3. The 0th entry is a connection to SQLExpress
Name: LocalSqlServer,
ConnectionString: data source=.\\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true
为什么被列入这方面，即使它不是在我的app.config，以及我怎样才能摆脱它？这code将在台式机，我都进不去运行 - 这样我怎么能prevent从随机显示在运行时更多的本地连接？我看不出在连接上的任何属性，表明它有什么不同，从我定义的两个。
Why is this connection being included even though it's not in my app.config, and how can I get rid of it? This code will be running on desktop machines that I have no access to - so how can I prevent any more local connections from randomly showing up at runtime? I can't see any properties on the connection that indicate it's any different from the two I defined.
推荐答案
它在machine.config中定义。为了摆脱它，使用：
It's defined in machine.config. To get rid of it, use:
<connectionStrings>
<clear/>
<add ... >
</connectionStrings>
作为一般规则，部分具有＆LT;添加＆gt; 和＆LT;删除＆GT; 元素（例如的appSettings ，的ConnectionStrings 和提供配置部分）也有一个＆LT;清＆GT; 元素，你可以使用，如果你不想继承一个更高级别的Web.config或machine.config文件的元素。
As a general rule, sections that have <add> and <remove> elements (e.g. appSettings, connectionStrings and the provider configuration sections) also have a <clear> element, which you can use if you don't want to inherit elements from a higher level web.config or machine.config file.
