asp.net - Web.config 文件中appSettings 和connectionStrings 之间的区别？

Question

为什么还有一个名为connectionStrings的部分？我一直只使用 appSettings，直到我在一个新项目中注意到这一点:

<appSettings>
 <add key="SqlConnString" value="server=ABC;database=ABC;uid=A;pwd=B;"/>
</appSettings>

<connectionStrings>    
</connectionStrings>

有什么区别吗？我有什么理由应该使用其中一种而不是另一种？

Answer 1

来自documentation :

The connectionStrings element specifies a collection of database connection strings, as name/value pairs, for ASP.NET applications and features.

In previous versions of ASP.NET, connection strings were stored in the appSettings. In ASP.NET 2.0, features, such as Session, Membership, Personalization, and Role Manager, rely on connection strings that are stored in the connectionStrings element. You can also use the connectionStrings element to store connection strings for your own applications.

因此，唯一真正的区别是内置的 ASP.NET 2.0 功能将期望其连接字符串位于 connectionStrings 区域中。
