C# 如何将ASP.NET应用程序部署到生产计算机，而不必手动更改DB连接字符串

目前，当我部署web应用程序时，我总是在部署应用程序之前进入web.config文件，手动更改连接字符串中的服务器名称等。有没有更简单的方法来部署web应用程序，而不必始终更改连接字符串中的服务器

谢谢

我们正是为了这个目的而使用的

它可以定制，就像在我的例子中一样，在安装时选择DEV、QA或PROD env

最好的方法是它使用底层MSI安装框架，如果这个词在这里正确的话。

在部署Web应用程序项目时使用transform Web.config：

这取决于您如何部署web应用程序，但一种常见的方法是使用web.config转换

假设您只需要更改一个特定Web部署的连接字符串，那么您可以像其他人所说的那样通过转换来完成。下面应该确切地说明您需要做什么

在解决方案资源管理器中，展开“属性”节点以获取PublishProperties，如下所示

您将在Web配置节点中获得一个Web.project-Web Deploy.config文件。初步内容如下

      <connectionStrings>
        <add name="MyDB" 
          connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"

将示例更改为以下内容或添加以下内容

        <add name="MyDB" 
          connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"

</system.web>

<connectionStrings>
  <add name="csname"
    connectionString="yourotherconnectionstring"
    xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>

其中csname是Web.config中需要在部署中替换的连接字符串的名称

还有许多其他转换是可能的，但是如果您只需要更改特定Web部署的连接字符串，那么这应该是最直接的。这意味着您要搜索具有指定名称的连接字符串，然后在部署过程中更改连接字符串值。

您目前正在使用什么进行部署？当我仅用一个链接发布这样的答案时，我会被否决。现在该链接不受支持且已过期。这两个链接对我都适用。哪一个链接“过时”以及原因？你看不到这些页面顶部的消息说我们不再定期更新此内容。？How:Transform Web.config文章的问题是，如果不存在转换文件。。。右键单击Web.config文件无效。我已经发布了一个答案，我希望将来能帮助别人。
