在本地运行Web应用程序的Web.Debug.config与Web.Release.config [英] Web.Debug.config vs. Web.Release.config running web app in localhost

问题描述

我有一个Web.config文件，其中包含一些条目，但是要根据我在本地执行Web应用程序时是处于调试模式还是发布模式，我想采用不同的appSettings.

I have a Web.config file with some entries in there but depending on whether I am in Debug or Release mode when I execute my Web Application locally, I want to take different appSettings.

例如，假设我在Web.Debug.config appSettings中具有以下条目.

For instance, let's say that I have the following entry in my Web.Debug.config appSettings.

<add key="MyServiceUrl" value="http://my-test-site:8080/" />

我的Web.Release.config中也有这个

And also I have this in my Web.Release.config:

<add key="MyServiceUrl" value="http://my-prod-site:80/" />

我应该如何配置Web.Config，Web.Debug.Config和Web.Release.Config，以便根据我在本地运行应用程序的模式(调试-任何CPU 与发布-任何CPU )，需要正确的CPU吗?

How should I configure my Web.Config, Web.Debug.Config and Web.Release.Config so depending on the mode I run my application locally (Debug - Any CPU vs. Release - Any CPU), it takes the right one?

现在，无论我在Visual Studio中选择调试"还是发布"，它唯一需要的一对键和值就是来自主Web.Config的键和值.

Right now, the only pair of key and value that it takes is the one from the main Web.Config regardless I select Debug or Release in Visual Studio.

如何配置该行为?

编辑

这就是我定义Web.config的方式

This is how I have defined Web.config

<appSettings>
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

这就是我定义Web.Debug.config

This is how I have defined Web.Debug.config

<appSettings>
     <add key="MyServiceUrl" value="http://my-test-site:8080/" xdt:Transform="SetAttributes" xdt:Locator="Match(key)"/>
</appSettings>

这就是我定义Web.Release.config

This is how I have defined Web.Release.config

<appSettings>
     <add key="MyServiceUrl" value="http://my-prod-site:8080/" xdt:Transform="SetAttributes" xdt:Locator="Match(key)" />
</appSettings>

最后，在我的代码中，我有以下方法:

Finally, in my code, I have the following method:

public static string GetAppSetting(string settingKey)
        {
            if (string.IsNullOrEmpty(settingKey))
                throw new System.ArgumentException("Cannot fetch a setting for a null/empty setting key.");
            return ConfigurationManager.AppSettings[settingKey];
        }

我这样称呼它: 字符串设置= GetAppSetting("MyServiceUrl");

which I call it like this: string setting = GetAppSetting("MyServiceUrl");

但是，如果未在主Web.config中定义，则为null

However, it is null if it is not defined in the main Web.config

推荐答案

在web.Release.config中尝试一下，它应该可以工作:

In the web.Release.config try this, it should work:

<appSettings>
 <add key="MyServiceUrl" value="http://my-prod-site:8080/" xdt:Transform="Insert" />
</appSettings>
