asp.net web.config 转换不起作用

Question

我在一个项目中针对不同的环境做了几个配置，一个是debug，另一个是release

Web.config：

<configuration>
  <connectionStrings>
    <add name="InvitationEntity" connectionString="metadata=res://*/Models.InvitationSystem.csdl|res://*/Models.InvitationSystem.ssdl|res://*/Models.InvitationSystem.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.7.131;initial catalog=Invitation_Debug;persist security info=True;user id=invitation;password=debugMe;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
  <appSettings>
    <add key="FilePath" value="D:\temp"/>
    <add key="debugMode" value="Y"/>
  </appSettings>
</configuration>

Web.debug.config：

   <?xml version="1.0" encoding="utf-8"?>

    <!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->

    <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
      <!--
        In the example below, the "SetAttributes" transform will change the value of 
        "connectionString" to use "ReleaseSQLServer" only when the "Match" locator 
        finds an attribute "name" that has a value of "MyDB".

        <connectionStrings>
          <add name="MyDB" 
            connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True" 
            xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
        </connectionStrings>
      -->
      <system.web>
        <!--
          In the example below, the "Replace" transform will replace the entire 
          <customErrors> section of your web.config file.
          Note that because there is only one customErrors section under the 
          <system.web> node, there is no need to use the "xdt:Locator" attribute.

          <customErrors defaultRedirect="GenericError.htm"
            mode="RemoteOnly" xdt:Transform="Replace">
            <error statusCode="500" redirect="InternalError.htm"/>
          </customErrors>
        -->
      </system.web>
  <connectionStrings xdt:Transform="Replace">
        <add name="InvitationEntity" connectionString="metadata=res://*/Models.InvitationSystem.csdl|res://*/Models.InvitationSystem.ssdl|res://*/Models.InvitationSystem.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.7.131;initial catalog=Invitation_Debug;persist security info=True;user id=invitation;password=debugMe;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
      </connectionStrings>
    </configuration>

Web.live.config：

   <?xml version="1.0" encoding="utf-8"?>

    <!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->

    <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
      <!--

        <connectionStrings>
          <add name="MyDB" 
            connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True" 
            xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
        </connectionStrings>
      -->
      <system.web>
        <!--

            mode="RemoteOnly" xdt:Transform="Replace">

          </customErrors>
        -->
      </system.web>
  <connectionStrings xdt:Transform="Replace">
        <add name="InvitationEntity" connectionString="metadata=res://*/Models.InvitationSystem.csdl|res://*/Models.InvitationSystem.ssdl|res://*/Models.InvitationSystem.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.7.133;initial catalog=Invitation_Debug;persist security info=True;user id=invitation;password=Invi#2014;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
      </connectionStrings>
    </configuration>

问题来了：

每当我使用调试或发布配置时，连接字符串仍然是 web.config 中的连接字符串，而不是 web.release.config 中的连接字符串

是不是我做错了什么？

Answer 1

有时使用逐项转换会更好。而不是部分替换使用

<add name="InvitationEntity" connectionString="metadata=res://*/Models.InvitationSystem.csdl|res://*/Models.InvitationSystem.ssdl|res://*/Models.InvitationSystem.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.7.133;initial catalog=Invitation_Debug;persist security info=True;user id=invitation;password=Invi#2014;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" xdt:Transform="Replace" xdt:Locator="Match(name)"/>

当您在节点中有很多属性并且只需要更改一个时，使用这种方法非常有用，例如您只需使用 SetAttributes 而不是 Replace。

Answer 2

您的发布构建设置是否使用 Web.live.config 文件？默认情况下，Release 需要一个名为 Web.Release.Config 的文件，我只是提到这一点，因为该文件被列为 Web.live.config，但您称它为“Release”。如果这只是一个拼写错误并且名称一致，或者如果您的发布构建配置设置为“实时”，那么请忽略它。

Answer 3

对我来说，转到转换文件的属性并更改属性； Copy to Output Directory 到 Copy Always 成功了。得到了Matt Kogaj's answer的提示

Answer 4

您必须删除 ConnectionString 标记中的属性 xdt:Transform。如下所示；

<connectionStrings>
    <add name="InvitationEntity" connectionString="metadata=res://*/Models.InvitationSystem.csdl|res://*/Models.InvitationSystem.ssdl|res://*/Models.InvitationSystem.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.7.133;initial catalog=Invitation_Debug;persist security info=True;user id=invitation;password=Invi#2014;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
