为什么app.config的控制台应用包含{}

<!-- Server Parameters-->
<add key="DatabaseServerName" value="MySqlServer"/>

<!-- Data Access Parameters-->
<add key="DataAccessConnectionString" value="server='{DATABASESERVERNAME}';uid='UserName';pwd=password;database='Database1';Trusted_Connection=Yes;initial catalog='Database1';Async=true; MultipleActiveResultSets=true"/>

我在这里或在Google上找不到有关此的信息。我有一个vb.net控制台应用程序，该应用程序已继承在app.config中，我无法弄清楚为什么它在那里或应该做什么。 {DatabaseserVername}使我感到困惑。它似乎在产品中正常工作，但是当我尝试在开发中使用它时，它失败了。我猜想它是对数据库媒体键中值的某种参数引用，但是我不明白为什么当我尝试运行此功能时它只是不起作用。 DataAccessConneTectionsTring只是带有server ='{databaseservername}'; uid ='username'; pwd = password; database ='database1'; trusted_connection = yes; ointer catalog ='data alog ='database1'; async = true;多重反应Viveresultsets =是的，

有人对此约定一无所知吗？

谢谢

I could not find anything about this here or on Google. I have a VB.Net console app that I have inherited that has tis in the app.config and I cannot figure out why it is there nor what it is supposed to do. The {DATABASESERVERNAME} is confusing to me. It seems to work fine in prod, but it is failing when I try to use it in dev. I am guessing that it some kind of parameter reference to the value in the DatabaseServerName key, but I do not understand why it just doesn't work when I try to run this. The DataAccessConnectionString just comes back with server='{DATABASESERVERNAME}';uid='UserName';pwd=password;database='Database1';Trusted_Connection=Yes;initial catalog='Database1';Async=true; MultipleActiveResultSets=true

Anyone know anything about this convention?

Thanks
