ASP.NET MVC 2 中的 Web.config 转换和额外的 Web.config 文件

发布于 2024-10-08 10:29:02 字数 737 浏览 8 评论 0原文

我正在尝试在 .NET 4 上运行的 ASP.NET MVC 2 项目中使用 Web.config 转换。但是，我遇到了问题：

// Root Web.config
<add name="MyDB" connectionString="default...default" />


// Root Web.Debug.config
<add name="MyDB" connectionString="debug...debug" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />

// Root Web.Release.config
<add name="MyDB" connectionString="release... release" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />

我不断收到此错误：

警告源文档中没有元素匹配“/configuration/add[@name='MyDB']”C:\filePath\Web.Release.config

我将范围缩小到 Views 文件夹内的 Web.Config 文件。如果我给它一个连接字符串，例如根 Web.config 文件中的连接字符串，那么一切都很好，但这意味着我必须维护两个 Web.config 文件。有什么办法解决这个问题吗？我做错了什么吗？

i'm trying to use the Web.config transformations in my ASP.NET MVC 2 project running on .NET 4. However, I am having a problem:

// Root Web.config
<add name="MyDB" connectionString="default...default" />


// Root Web.Debug.config
<add name="MyDB" connectionString="debug...debug" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />

// Root Web.Release.config
<add name="MyDB" connectionString="release... release" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />

I keep getting this error:

Warning No element in the source document matches '/configuration/add[@name='MyDB']' C:\filePath\Web.Release.config

I narrowed this down to the Web.Config file inside the Views folder. If I give it a connectionString, such as the one in the root Web.config file, than all is well, but that means I have to maintain two Web.config files. Is there any solution to this? Am I doing something wrong?

不确定为什么视图文件夹中的 web.config 受到牵连，但从您收到的错误来看，听起来 web.config 中的元素与转换配置文件之间不匹配。

在 web.config 中，假设是的子级，您会这样做：

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

<configuration>

...

    <connectionStrings>
        <add name="SomeName" providerName="System.Data.SqlClient" connectionString="SomeConnectionString" />
    </connectionStrings>

...

</configuration>

在 web.debug.config 中

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

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

...

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

...

</configuration>

Not sure why web.config in the views folder is being implicated but from the error you're getting it sounds like you've got a mismatch between the element in web.config and the transform config files.

In web.config, assuming <add /> is a child of <connectionStrings /> you'd do:

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

<configuration>

...

    <connectionStrings>
        <add name="SomeName" providerName="System.Data.SqlClient" connectionString="SomeConnectionString" />
    </connectionStrings>

...

</configuration>

and in web.debug.config

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

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

...

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

...

</configuration>
