是的，我得到了解决。 由于鲍勃·霍恩和 JoeBilly 的宝贵意见。

我已经实现了配置按我的要求。我寻觅了很多了完整的解决方案，但总是得到的概念和小块code，这就是为什么我提供了完整的工作code。

通过下述$ C $的帮助c可以实现以下和配置玩你想要的。

1. 常见配置 [CommonDB] 可以被定义为一个单一的 存储库，并且可以存储在外部XML文件中。类库将越来越为网络总是一个值，以及Windows应用程序。
2. 网站的具体配置 [WebDBConn] 可以存储在web.config中。
3. 窗口应用程序特定的配置 [WindowDBConn] 可提及的app.config。
4. 如果您要使用相同的密钥不同的值 [INPUT_PATH] 为每个应用程序，然后使用相同的密钥和差异值wen.config和App.config中。但请记住，关键不应该在common.config其他明智的值，它是在common.config可将有所回升可用。
5. 的好处是，您不必恰克背后的方法您code 获取这些值。

Common.Config 的类库/常见配置。

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;的appSettings＆GT;
    ＆LT;添加键=CommonDB值=CommonDBValue/＆GT;
＆LT; /的appSettings＆GT;
 

Web.config中的网站

 ＆lt;结构＆GT;
    ＆LT;的appSettings文件=D：\ Common.config＆GT;
        ＆LT;添加键=WebDBConn值=WebDBConnValue/＆GT;
        ＆LT;添加键=INPUT_PATH值=INPUT_PATH_WEB/＆GT;
    ＆LT; /的appSettings＆GT;
＆LT; /结构＆gt;
 

的App.config 的Windows应用程序

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆lt;结构＆GT;
    ＆LT;的appSettings文件=D：\ Common.config＆GT;
        ＆LT;添加键=WindowDBConn值=WindowDBConnValue/＆GT;
        ＆LT;添加键=INPUT_PATH值=INPUT_PATH_WINDOW/＆GT;
    ＆LT; /的appSettings＆GT;
＆LT; /结构＆gt;

谢谢...

I have created a Class Library (Core Processing Component) using C# in Visual Studio 2008 and added the reference in Website. Website accessing the class library successfully. Web.config having some configuration values, which is used by the Class Library.

Now, I want to access the same component and configuration in a Window Application (C# VS-2k8). I am able to access the same class library in window application.

But, How do i Share the Web.config file of website with the Window Application? So that, i don't have to replicate the same configuration.

Thanks.

Update# 1

Further detail on Question 1: I would like to add config file in Class Library instead of having dependent on application's config file. E.g. web.config in website or app.config in windows application.

This is to reduce the duplicacy/conflicts of same configurations in multiple apps.

Update# 2

I am using the following code to get the configuration from the external location from window and web application. But it is not working for me.

D:\test.exe.config file

<configuration>
  <appSettings>
    <add key="KeyName" value="KeyValue"/>
  </appSettings>
</configuration>

Code Behind:

Configuration config = ConfigurationManager.OpenExeConfiguration("D:\\test.exe.config");
            string strValue = config.AppSettings.Settings["KeyName"].Value;

Yes, I got the solution. Thanks to Bob Horn and JoeBilly for valuable inputs.

I have implemented the configuration as per my requirement. I have searched a lot for the complete solution but always getting the concepts and small piece of code, that's why i am providing the complete working code.

With the help of below mentioned code you can achieve the followings and play with the configuration as you want.

1. Common Configuration [CommonDB] can be defined as a single repository and can be stored in external XML file. Class library will be getting always one value for web as well as windows application.
2. Website specific configuration [WebDBConn] can be stored in web.config.
3. Window Application specific configuration [WindowDBConn] can be mentioned in app.config.
4. If you want to use same Key with Different values [INPUT_PATH] as per the application, then use same key and the diff values in wen.config and app.config. But remember that key should not be available in the common.config other wise the value which is available in the common.config will be picked up.
5. The good thing is that you don't have to chage your code behind approach for getting these values.

Common.Config for Class Library/Common configuration

<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
    <add key="CommonDB" value="CommonDBValue" />    
</appSettings>

Web.Config for Website

<configuration>
    <appSettings file="D:\Common.config">
        <add key="WebDBConn" value="WebDBConnValue" />
        <add key="INPUT_PATH" value="INPUT_PATH_WEB" />
    </appSettings>
</configuration>

App.config for Windows Application

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <appSettings file="D:\Common.config">
        <add key="WindowDBConn" value="WindowDBConnValue" />
        <add key="INPUT_PATH" value="INPUT_PATH_WINDOW" />
    </appSettings>
</configuration>

Code behind

string configValue = ConfigurationSettings.AppSettings["CommonDB"];

Thanks...
